Merge lp:~sbeattie/ubuntu/oneiric/openssl/lp850608 into lp:ubuntu/oneiric/openssl

[Steve Beattie]

This branch merges openssl-1.0.0e-2 from Debian unstable to fix security issues. Both the debian changes from 1.0.0d-2 and the upstream release 1.0.0e are bugfix only releases. This merge also includes an added fix for LP: #244250 (reduce spurious reboot warnings on desktop installs) by checking for a running X server to determine whether or not to issue the reboot notification.

[Marc Deslauriers (mdeslaur)]

Looks good. Uploaded.

+=head1 DESCRIPTION
+
+The digest functions output the message digest of a supplied file or files
+in hexadecimal form. They can also be used for digital signing and verification.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-c>
+
+print out the digest in two digit groups separated by colons, only relevant if
+B<hex> format output is used.
+
+=item B<-d>
+
+print out BIO debugging information.
+
+=item B<-hex>
+
+digest is to be output as a hex dump. This is the default case for a "normal"
+digest as opposed to a digital signature.
+
+=item B<-binary>
+
+output the digest or signature in binary form.
+
+=item B<-out filename>
+
+filename to output to, or standard output by default.
+
+=item B<-sign filename>
+
+digitally sign the digest using the private key in "filename".
+
+=item B<-keyform arg>
+
+Specifies the key format to sign digest with. Only PEM and ENGINE
+formats are supported by the B<dgst> command.
+
+=item B<-engine id>
+
+Use engine B<id> for operations (including private key storage).
+This engine is not used as source for digest algorithms, unless it is
+also specified in the configuration file.
+
+=item B<-sigopt nm:v>
+
+Pass options to the signature algorithm during sign or verify operations.
+Names and values of these options are algorithm-specific.
+
+
+=item B<-passin arg>
+
+the private key password source. For more information about the format of B<arg>
+see the B<PASS PHRASE ARGUMENTS> section in L<openssl(1)|openssl(1)>.
+
+=item B<-verify filename>
+
+verify the signature using the the public key in "filename".
+The output is either "Verification OK" or "Verification Failure".
+
+=item B<-prverify filename>
+
+verify the signature using the  the private key in "filename".
+
+=item B<-signature filename>
+
+the actual signature to verify.
+
+=item B<-hmac key>
+
+create a hashed MAC using "key".
+
+=item B<-mac alg>
+
+create MAC (keyed Message Authentication Code). The most popular MAC
+algorithm is HMAC (hash-based MAC), but there are other MAC algorithms
+which are not based on hash, for instance B<gost-mac> algorithm,
+supported by B<ccgost> engine. MAC keys and other options should be set
+via B<-macopt> parameter.
+
+=item B<-macopt nm:v>
+
+Passes options to MAC algorithm, specified by B<-mac> key.
+Following options are supported by both by B<HMAC> and B<gost-mac>:
+
+=over 8
+
+=item B<key:string>
+	
+Specifies MAC key as alphnumeric string (use if key contain printable
+characters only). String length must conform to any restrictions of
+the MAC algorithm for example exactly 32 chars for gost-mac.
+
+=item B<hexkey:string>
+
+Specifies MAC key in hexadecimal form (two hex digits per byte).
+Key length must conform to any restrictions of the MAC algorithm
+for example exactly 32 chars for gost-mac.
+
+=back
+
+=item B<-rand file(s)>
+
+a file or files containing random data used to seed the random number
+generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>).
+Multiple files can be specified separated by a OS-dependent character.
+The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
+all others. 
+
+=item B<file...>
+
+file or files to digest. If no files are specified then standard input is
+used.
+
+=back
+
+=head1 NOTES
+
+The digest of choice for all new applications is SHA1. Other digests are
+however still widely used.
+
+If you wish to sign or verify data using the DSA algorithm then the dss1
+digest must be used.
+
+A source of random numbers is required for certain signing algorithms, in
+particular DSA.
+
+The signing and verify options should only be used if a single file is
+being signed or verified.

+=head1 NAME
+
+ASN1_generate_nconf, ASN1_generate_v3 - ASN1 generation functions
+
+=head1 SYNOPSIS
+
+ #include <openssl/asn1.h>
+
+ ASN1_TYPE *ASN1_generate_nconf(char *str, CONF *nconf);
+ ASN1_TYPE *ASN1_generate_v3(char *str, X509V3_CTX *cnf);
+
+=head1 DESCRIPTION
+
+These functions generate the ASN1 encoding of a string
+in an B<ASN1_TYPE> structure.
+
+B<str> contains the string to encode B<nconf> or B<cnf> contains
+the optional configuration information where additional strings
+will be read from. B<nconf> will typically come from a config
+file wherease B<cnf> is obtained from an B<X509V3_CTX> structure
+which will typically be used by X509 v3 certificate extension
+functions. B<cnf> or B<nconf> can be set to B<NULL> if no additional
+configuration will be used.
+
+=head1 GENERATION STRING FORMAT
+
+The actual data encoded is determined by the string B<str> and
+the configuration information. The general format of the string
+is:
+
+=over 2
+
+=item B<[modifier,]type[:value]>
+
+=back
+
+That is zero or more comma separated modifiers followed by a type
+followed by an optional colon and a value. The formats of B<type>,
+B<value> and B<modifier> are explained below.
+
+=head2 SUPPORTED TYPES
+
+The supported types are listed below. Unless otherwise specified
+only the B<ASCII> format is permissible.
+
+=over 2
+
+=item B<BOOLEAN>, B<BOOL>
+
+This encodes a boolean type. The B<value> string is mandatory and
+should be B<TRUE> or B<FALSE>. Additionally B<TRUE>, B<true>, B<Y>,
+B<y>, B<YES>, B<yes>, B<FALSE>, B<false>, B<N>, B<n>, B<NO> and B<no>
+are acceptable. 
+
+=item B<NULL>
+
+Encode the B<NULL> type, the B<value> string must not be present.
+
+=item B<INTEGER>, B<INT>
+
+Encodes an ASN1 B<INTEGER> type. The B<value> string represents
+the value of the integer, it can be preceeded by a minus sign and
+is normally interpreted as a decimal value unless the prefix B<0x>
+is included.
+
+=item B<ENUMERATED>, B<ENUM>
+
+Encodes the ASN1 B<ENUMERATED> type, it is otherwise identical to
+B<INTEGER>.
+
+=item B<OBJECT>, B<OID>
+
+Encodes an ASN1 B<OBJECT IDENTIFIER>, the B<value> string can be
+a short name, a long name or numerical format.
+
+=item B<UTCTIME>, B<UTC>
+
+Encodes an ASN1 B<UTCTime> structure, the value should be in
+the format B<YYMMDDHHMMSSZ>. 
+
+=item B<GENERALIZEDTIME>, B<GENTIME>
+
+Encodes an ASN1 B<GeneralizedTime> structure, the value should be in
+the format B<YYYYMMDDHHMMSSZ>. 
+
+=item B<OCTETSTRING>, B<OCT>
+
+Encodes an ASN1 B<OCTET STRING>. B<value> represents the contents
+of this structure, the format strings B<ASCII> and B<HEX> can be
+used to specify the format of B<value>.
+
+=item B<BITSTRING>, B<BITSTR>
+
+Encodes an ASN1 B<BIT STRING>. B<value> represents the contents
+of this structure, the format strings B<ASCII>, B<HEX> and B<BITLIST>
+can be used to specify the format of B<value>.
+
+If the format is anything other than B<BITLIST> the number of unused
+bits is set to zero.
+
+=item B<UNIVERSALSTRING>, B<UNIV>, B<IA5>, B<IA5STRING>, B<UTF8>,
+B<UTF8String>, B<BMP>, B<BMPSTRING>, B<VISIBLESTRING>,
+B<VISIBLE>, B<PRINTABLESTRING>, B<PRINTABLE>, B<T61>,
+B<T61STRING>, B<TELETEXSTRING>, B<GeneralString>, B<NUMERICSTRING>,
+B<NUMERIC>
+
+These encode the corresponding string types. B<value> represents the
+contents of this structure. The format can be B<ASCII> or B<UTF8>.
+
+=item B<SEQUENCE>, B<SEQ>, B<SET>
+
+Formats the result as an ASN1 B<SEQUENCE> or B<SET> type. B<value>
+should be a section name which will contain the contents. The
+field names in the section are ignored and the values are in the
+generated string format. If B<value> is absent then an empty SEQUENCE
+will be encoded.
+
+=back
+
+=head2 MODIFIERS
+
+Modifiers affect the following structure, they can be used to
+add EXPLICIT or IMPLICIT tagging, add wrappers or to change
+the string format of the final type and value. The supported
+formats are documented below.
+
+=over 2
+
+=item B<EXPLICIT>, B<EXP>
+
+Add an explicit tag to the following structure. This string
+should be followed by a colon and the tag value to use as a
+decimal value.
+
+By following the number with B<U>, B<A>, B<P> or B<C> UNIVERSAL,
+APPLICATION, PRIVATE or CONTEXT SPECIFIC tagging can be used,
+the default is CONTEXT SPECIFIC.
+
+=item B<IMPLICIT>, B<IMP>
+
+This is the same as B<EXPLICIT> except IMPLICIT tagging is used
+instead.
+
+=item B<OCTWRAP>, B<SEQWRAP>, B<SETWRAP>, B<BITWRAP>
+
+The following structure is surrounded by an OCTET STRING, a SEQUENCE,
+a SET or a BIT STRING respectively. For a BIT STRING the number of unused
+bits is set to zero.
+
+=item B<FORMAT>
+
+This specifies the format of the ultimate value. It should be followed
+by a colon and one of the strings B<ASCII>, B<UTF8>, B<HEX> or B<BITLIST>.
+
+If no format specifier is included then B<ASCII> is used. If B<UTF8> is
+specified then the value string must be a valid B<UTF8> string. For B<HEX> the
+output must be a set of hex digits. B<BITLIST> (which is only valid for a BIT
+STRING) is a comma separated list of the indices of the set bits, all other
+bits are zero.
+
+=back
+
+=head1 EXAMPLES
+
+A simple IA5String:
+
+ IA5STRING:Hello World
+
+An IA5String explicitly tagged:
+
+ EXPLICIT:0,IA5STRING:Hello World
+
+An IA5String explicitly tagged using APPLICATION tagging:
+
+ EXPLICIT:0A,IA5STRING:Hello World
+
+A BITSTRING with bits 1 and 5 set and all others zero:
+
+ FORMAT:BITLIST,BITSTRING:1,5
+
+A more complex example using a config file to produce a
+SEQUENCE consiting of a BOOL an OID and a UTF8String:
+
+ asn1 = SEQUENCE:seq_section
+
+ [seq_section]
+
+ field1 = BOOLEAN:TRUE
+ field2 = OID:commonName
+ field3 = UTF8:Third field
+
+This example produces an RSAPrivateKey structure, this is the
+key contained in the file client.pem in all OpenSSL distributions

+=head1 DESCRIPTION
+
+BN_BLINDING_new() allocates a new B<BN_BLINDING> structure and copies
+the B<A> and B<Ai> values into the newly created B<BN_BLINDING> object.
+
+BN_BLINDING_free() frees the B<BN_BLINDING> structure.
+
+BN_BLINDING_update() updates the B<BN_BLINDING> parameters by squaring
+the B<A> and B<Ai> or, after specific number of uses and if the
+necessary parameters are set, by re-creating the blinding parameters.
+
+BN_BLINDING_convert_ex() multiplies B<n> with the blinding factor B<A>.
+If B<r> is not NULL a copy the inverse blinding factor B<Ai> will be
+returned in B<r> (this is useful if a B<RSA> object is shared amoung
+several threads). BN_BLINDING_invert_ex() multiplies B<n> with the
+inverse blinding factor B<Ai>. If B<r> is not NULL it will be used as
+the inverse blinding.
+
+BN_BLINDING_convert() and BN_BLINDING_invert() are wrapper
+functions for BN_BLINDING_convert_ex() and BN_BLINDING_invert_ex()
+with B<r> set to NULL.

+
+EVP_BytesToKey - password based encryption routine
+
+=head1 SYNOPSIS
+
+ #include <openssl/evp.h>
+
+ int EVP_BytesToKey(const EVP_CIPHER *type,const EVP_MD *md,
+                       const unsigned char *salt,
+                       const unsigned char *data, int datal, int count,
+                       unsigned char *key,unsigned char *iv);
+
+=head1 DESCRIPTION
+
+EVP_BytesToKey() derives a key and IV from various parameters. B<type> is
+the cipher to derive the key and IV for. B<md> is the message digest to use.
+The B<salt> paramter is used as a salt in the derivation: it should point to
+an 8 byte buffer or NULL if no salt is used. B<data> is a buffer containing
+B<datal> bytes which is used to derive the keying data. B<count> is the
+iteration count to use. The derived key and IV will be written to B<key>
+and B<iv> respectively.
+
+=head1 NOTES
+
+A typical application of this function is to derive keying material for an
+encryption algorithm from a password in the B<data> parameter.
+
+Increasing the B<count> parameter slows down the algorithm which makes it
+harder for an attacker to peform a brute force attack using a large number
+of candidate passwords.
+
+If the total key and IV length is less than the digest length and
+B<MD5> is used then the derivation algorithm is compatible with PKCS#5 v1.5
+otherwise a non standard extension is used to derive the extra data.
+
+Newer applications should use more standard algorithms such as PKCS#5
+v2.0 for key derivation.
+
+=head1 KEY DERIVATION ALGORITHM
+
+The key and IV is derived by concatenating D_1, D_2, etc until
+enough data is available for the key and IV. D_i is defined as:
+
+	D_i = HASH^count(D_(i-1) || data || salt)
+
+where || denotes concatentaion, D_0 is empty, HASH is the digest
+algorithm in use, HASH^1(data) is simply HASH(data), HASH^2(data)
+is HASH(HASH(data)) and so on.
+
+The initial bytes are used for the key and the subsequent bytes for
+the IV.
+
+=head1 RETURN VALUES
+
+EVP_BytesToKey() returns the size of the derived key in bytes.

+=head1 DESCRIPTION
+
+The EVP cipher routines are a high level interface to certain
+symmetric ciphers.
+
+EVP_CIPHER_CTX_init() initializes cipher contex B<ctx>.
+
+EVP_EncryptInit_ex() sets up cipher context B<ctx> for encryption
+with cipher B<type> from ENGINE B<impl>. B<ctx> must be initialized
+before calling this function. B<type> is normally supplied
+by a function such as EVP_des_cbc(). If B<impl> is NULL then the
+default implementation is used. B<key> is the symmetric key to use
+and B<iv> is the IV to use (if necessary), the actual number of bytes
+used for the key and IV depends on the cipher. It is possible to set
+all parameters to NULL except B<type> in an initial call and supply
+the remaining parameters in subsequent calls, all of which have B<type>
+set to NULL. This is done when the default cipher parameters are not
+appropriate.
+
+EVP_EncryptUpdate() encrypts B<inl> bytes from the buffer B<in> and
+writes the encrypted version to B<out>. This function can be called
+multiple times to encrypt successive blocks of data. The amount
+of data written depends on the block alignment of the encrypted data:
+as a result the amount of data written may be anything from zero bytes
+to (inl + cipher_block_size - 1) so B<outl> should contain sufficient
+room. The actual number of bytes written is placed in B<outl>.
+
+If padding is enabled (the default) then EVP_EncryptFinal_ex() encrypts
+the "final" data, that is any data that remains in a partial block.
+It uses L<standard block padding|/NOTES> (aka PKCS padding). The encrypted
+final data is written to B<out> which should have sufficient space for
+one cipher block. The number of bytes written is placed in B<outl>. After
+this function is called the encryption operation is finished and no further
+calls to EVP_EncryptUpdate() should be made.
+
+If padding is disabled then EVP_EncryptFinal_ex() will not encrypt any more
+data and it will return an error if any data remains in a partial block:
+that is if the total data length is not a multiple of the block size. 
+
+EVP_DecryptInit_ex(), EVP_DecryptUpdate() and EVP_DecryptFinal_ex() are the
+corresponding decryption operations. EVP_DecryptFinal() will return an
+error code if padding is enabled and the final block is not correctly
+formatted. The parameters and restrictions are identical to the encryption
+operations except that if padding is enabled the decrypted data buffer B<out>
+passed to EVP_DecryptUpdate() should have sufficient room for
+(B<inl> + cipher_block_size) bytes unless the cipher block size is 1 in
+which case B<inl> bytes is sufficient.
+
+EVP_CipherInit_ex(), EVP_CipherUpdate() and EVP_CipherFinal_ex() are
+functions that can be used for decryption or encryption. The operation
+performed depends on the value of the B<enc> parameter. It should be set
+to 1 for encryption, 0 for decryption and -1 to leave the value unchanged
+(the actual value of 'enc' being supplied in a previous call).
+
+EVP_CIPHER_CTX_cleanup() clears all information from a cipher context
+and free up any allocated memory associate with it. It should be called
+after all operations using a cipher are complete so sensitive information
+does not remain in memory.
+
+EVP_EncryptInit(), EVP_DecryptInit() and EVP_CipherInit() behave in a
+similar way to EVP_EncryptInit_ex(), EVP_DecryptInit_ex and
+EVP_CipherInit_ex() except the B<ctx> paramter does not need to be
+initialized and they always use the default cipher implementation.
+
+EVP_EncryptFinal(), EVP_DecryptFinal() and EVP_CipherFinal() behave in a
+similar way to EVP_EncryptFinal_ex(), EVP_DecryptFinal_ex() and
+EVP_CipherFinal_ex() except B<ctx> is automatically cleaned up 
+after the call.
+
+EVP_get_cipherbyname(), EVP_get_cipherbynid() and EVP_get_cipherbyobj()
+return an EVP_CIPHER structure when passed a cipher name, a NID or an
+ASN1_OBJECT structure.
+
+EVP_CIPHER_nid() and EVP_CIPHER_CTX_nid() return the NID of a cipher when
+passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX> structure.  The actual NID
+value is an internal value which may not have a corresponding OBJECT
+IDENTIFIER.
+
+EVP_CIPHER_CTX_set_padding() enables or disables padding. By default
+encryption operations are padded using standard block padding and the
+padding is checked and removed when decrypting. If the B<pad> parameter
+is zero then no padding is performed, the total amount of data encrypted
+or decrypted must then be a multiple of the block size or an error will
+occur.
+
+EVP_CIPHER_key_length() and EVP_CIPHER_CTX_key_length() return the key
+length of a cipher when passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX>
+structure. The constant B<EVP_MAX_KEY_LENGTH> is the maximum key length
+for all ciphers. Note: although EVP_CIPHER_key_length() is fixed for a
+given cipher, the value of EVP_CIPHER_CTX_key_length() may be different
+for variable key length ciphers.
+
+EVP_CIPHER_CTX_set_key_length() sets the key length of the cipher ctx.
+If the cipher is a fixed length cipher then attempting to set the key
+length to any value other than the fixed value is an error.
+
+EVP_CIPHER_iv_length() and EVP_CIPHER_CTX_iv_length() return the IV
+length of a cipher when passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX>.
+It will return zero if the cipher does not use an IV.  The constant
+B<EVP_MAX_IV_LENGTH> is the maximum IV length for all ciphers.
+
+EVP_CIPHER_block_size() and EVP_CIPHER_CTX_block_size() return the block
+size of a cipher when passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX>
+structure. The constant B<EVP_MAX_IV_LENGTH> is also the maximum block
+length for all ciphers.
+
+EVP_CIPHER_type() and EVP_CIPHER_CTX_type() return the type of the passed
+cipher or context. This "type" is the actual NID of the cipher OBJECT
+IDENTIFIER as such it ignores the cipher parameters and 40 bit RC2 and
+128 bit RC2 have the same NID. If the cipher does not have an object
+identifier or does not have ASN1 support this function will return
+B<NID_undef>.
+
+EVP_CIPHER_CTX_cipher() returns the B<EVP_CIPHER> structure when passed
+an B<EVP_CIPHER_CTX> structure.
+
+EVP_CIPHER_mode() and EVP_CIPHER_CTX_mode() return the block cipher mode:
+EVP_CIPH_ECB_MODE, EVP_CIPH_CBC_MODE, EVP_CIPH_CFB_MODE or
+EVP_CIPH_OFB_MODE. If the cipher is a stream cipher then
+EVP_CIPH_STREAM_CIPHER is returned.
+
+EVP_CIPHER_param_to_asn1() sets the AlgorithmIdentifier "parameter" based
+on the passed cipher. This will typically include any parameters and an
+IV. The cipher IV (if any) must be set when this call is made. This call
+should be made before the cipher is actually "used" (before any
+EVP_EncryptUpdate(), EVP_DecryptUpdate() calls for example). This function
+may fail if the cipher does not have any ASN1 support.
+
+EVP_CIPHER_asn1_to_param() sets the cipher parameters based on an ASN1
+AlgorithmIdentifier "parameter". The precise effect depends on the cipher
+In the case of RC2, for example, it will set the IV and effective key length.
+This function should be called after the base cipher type is set but before
+the key is set. For example EVP_CipherInit() will be called with the IV and
+key set to NULL, EVP_CIPHER_asn1_to_param() will be called and finally
+EVP_CipherInit() again with all parameters except the key set to NULL. It is
+possible for this function to fail if the cipher does not have any ASN1 support
+or the parameters cannot be set (for example the RC2 effective key length
+is not supported.
+
+EVP_CIPHER_CTX_ctrl() allows various cipher specific parameters to be determined
+and set. Currently only the RC2 effective key length and the number of rounds of
+RC5 can be set.

+
+=head1 NOTES
+
+Where possible the B<EVP> interface to symmetric ciphers should be used in
+preference to the low level interfaces. This is because the code then becomes
+transparent to the cipher used and much more flexible.
+
+PKCS padding works by adding B<n> padding bytes of value B<n> to make the total 
+length of the encrypted data a multiple of the block size. Padding is always
+added so if the data is already a multiple of the block size B<n> will equal
+the block size. For example if the block size is 8 and 11 bytes are to be
+encrypted then 5 padding bytes of value 5 will be added.
+
+When decrypting the final block is checked to see if it has the correct form.
+
+Although the decryption operation can produce an error if padding is enabled,
+it is not a strong test that the input data or key is correct. A random block
+has better than 1 in 256 chance of being of the correct format and problems with
+the input data earlier on will not produce a final decrypt error.
+
+If padding is disabled then the decryption operation will always succeed if
+the total amount of data decrypted is a multiple of the block size.
+
+The functions EVP_EncryptInit(), EVP_EncryptFinal(), EVP_DecryptInit(),
+EVP_CipherInit() and EVP_CipherFinal() are obsolete but are retained for
+compatibility with existing code. New code should use EVP_EncryptInit_ex(),
+EVP_EncryptFinal_ex(), EVP_DecryptInit_ex(), EVP_DecryptFinal_ex(),
+EVP_CipherInit_ex() and EVP_CipherFinal_ex() because they can reuse an
+existing context without allocating and freeing it up on each call.
+
+=head1 BUGS
+
+For RC5 the number of rounds can currently only be set to 8, 12 or 16. This is
+a limitation of the current RC5 code rather than the EVP interface.
+
+EVP_MAX_KEY_LENGTH and EVP_MAX_IV_LENGTH only refer to the internal ciphers with
+default key lengths. If custom ciphers exceed these values the results are
+unpredictable. This is because it has become standard practice to define a 
+generic key as a fixed unsigned char array containing EVP_MAX_KEY_LENGTH bytes.
+
+The ASN1 code is incomplete (and sometimes inaccurate) it has only been tested
+for certain common S/MIME ciphers (RC2, DES, triple DES) in CBC mode.

+=head1 DESCRIPTION
+
+The function EVP_PKEY_missing_parameters() returns 1 if the public key
+parameters of B<pkey> are missing and 0 if they are present or the algorithm
+doesn't use parameters.
+
+The function EVP_PKEY_copy_parameters() copies the parameters from key

+
+=head1 NOTES
+
+The main purpose of the functions EVP_PKEY_missing_parameters() and
+EVP_PKEY_copy_parameters() is to handle public keys in certificates where the
+parameters are sometimes omitted from a public key if they are inherited from
+the CA that signed it.
+
+Since OpenSSL private keys contain public key components too the function
+EVP_PKEY_cmp() can also be used to determine if a private key matches
+a public key.

+
+=head1 DESCRIPTION
+
+These functions are typically called after X509_verify_cert() has indicated
+an error or in a verification callback to determine the nature of an error.
+
+X509_STORE_CTX_get_error() returns the error code of B<ctx>, see
+the B<ERROR CODES> section for a full description of all error codes.
+
+X509_STORE_CTX_set_error() sets the error code of B<ctx> to B<s>. For example
+it might be used in a verification callback to set an error based on additional
+checks.
+
+X509_STORE_CTX_get_error_depth() returns the B<depth> of the error. This is a
+non-negative integer representing where in the certificate chain the error
+occurred. If it is zero it occured in the end entity certificate, one if
+it is the certificate which signed the end entity certificate and so on.
+
+X509_STORE_CTX_get_current_cert() returns the certificate in B<ctx> which
+caused the error or B<NULL> if no certificate is relevant.
+
+X509_STORE_CTX_get1_chain() returns a complete validate chain if a previous
+call to X509_verify_cert() is successful. If the call to X509_verify_cert()
+is B<not> successful the returned chain may be incomplete or invalid. The
+returned chain persists after the B<ctx> structure is freed, when it is
+no longer needed it should be free up using:
+
+  sk_X509_pop_free(chain, X509_free);
+
+X509_verify_cert_error_string() returns a human readable error string for
+verification error B<n>.
+
+=head1 RETURN VALUES
+
+X509_STORE_CTX_get_error() returns B<X509_V_OK> or an error code.
+
+X509_STORE_CTX_get_error_depth() returns a non-negative error depth.
+
+X509_STORE_CTX_get_current_cert() returns the cerificate which caused the
+error or B<NULL> if no certificate is relevant to the error.
+
+X509_verify_cert_error_string() returns a human readable error string for
+verification error B<n>.

+
+=item B<X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY: unable to get local issuer certificate>
+
+the issuer certificate of a locally looked up certificate could not be found.
+This normally means the list of trusted certificates is not complete.
+
+=item B<X509_V_ERR_UNABLE_TO_VERIFY_LEAF_SIGNATURE: unable to verify the first certificate>

+=item B<X509_V_ERR_SUBJECT_ISSUER_MISMATCH: subject issuer mismatch>
+
+the current candidate issuer certificate was rejected because its subject name
+did not match the issuer name of the current certificate. This is only set
+if issuer check debugging is enabled it is used for status notification and
+is B<not> in itself an error.
+
+=item B<X509_V_ERR_AKID_SKID_MISMATCH: authority and subject key identifier mismatch>
+
+the current candidate issuer certificate was rejected because its subject key
+identifier was present and did not match the authority key identifier current
+certificate. This is only set if issuer check debugging is enabled it is used
+for status notification and is B<not> in itself an error.
+
+=item B<X509_V_ERR_AKID_ISSUER_SERIAL_MISMATCH: authority and issuer serial number mismatch>
+
+the current candidate issuer certificate was rejected because its issuer name
+and serial number was present and did not match the authority key identifier of

+
+=item B<X509_V_ERR_KEYUSAGE_NO_CERTSIGN:key usage does not include certificate signing>
+
+the current candidate issuer certificate was rejected because its keyUsage
+extension does not permit certificate signing. This is only set if issuer check

+A certificate extension had an invalid value (for example an incorrect
+encoding) or some value inconsistent with other extensions.
+
+
+=item B<X509_V_ERR_INVALID_POLICY_EXTENSION: invalid or inconsistent certificate policy extension>
+
+A certificate policies extension had an invalid value (for example an incorrect
+encoding) or some value inconsistent with other extensions. This error only
+occurs if policy processing is enabled.
+
+=item B<X509_V_ERR_NO_EXPLICIT_POLICY: no explicit policy>
+
+The verification flags were set to require and explicit policy but none was
+present.
+
+=item B<X509_V_ERR_DIFFERENT_CRL_SCOPE: Different CRL scope>
+
+The only CRLs that could be found did not match the scope of the certificate.
+
+=item B<X509_V_ERR_UNSUPPORTED_EXTENSION_FEATURE: Unsupported extension feature>
+
+Some feature of a certificate extension is not supported. Unused.
+
+=item B<X509_V_ERR_PERMITTED_VIOLATION: permitted subtree violation>
+
+A name constraint violation occured in the permitted subtrees.
+
+=item B<X509_V_ERR_EXCLUDED_VIOLATION: excluded subtree violation>

+An unsupported name constraint type was encountered. OpenSSL currently only
+supports directory name, DNS name, email and URI types.
+
+=item B<X509_V_ERR_UNSUPPORTED_CONSTRAINT_SYNTAX: unsupported or invalid name constraint syntax>
+
+The format of the name constraint is not recognised: for example an email
+address format of a form not mentioned in RFC3280. This could be caused by
+a garbage extension or some new feature not currently supported.
+
+=item B<X509_V_ERR_CRL_PATH_VALIDATION_ERROR: CRL path validation error>
+
+An error occured when attempting to verify the CRL path. This error can only
+happen if extended CRL checking is enabled.
+
+=item B<X509_V_ERR_APPLICATION_VERIFICATION: application verification failure>
+
+an application specific error. This will never be returned unless explicitly
+set by an application.
+
+=head1 NOTES
+
+The above functions should be used instead of directly referencing the fields
+in the B<X509_VERIFY_CTX> structure.
+
+In versions of OpenSSL before 1.0 the current certificate returned by
+X509_STORE_CTX_get_current_cert() was never B<NULL>. Applications should
+check the return value before printing out any debugging information relating
+to the current certificate.
+
+If an unrecognised error code is passed to X509_verify_cert_error_string() the
+numerical value of the unknown code is returned in a static buffer. This is not
+thread safe but will never happen unless an invalid code is passed.

+=head1 DESCRIPTION
+
+The PEM functions read or write structures in PEM format. In
+this sense PEM format is simply base64 encoded data surrounded
+by header lines.
+
+For more details about the meaning of arguments see the
+B<PEM FUNCTION ARGUMENTS> section.
+
+Each operation has four functions associated with it. For
+clarity the term "B<foobar> functions" will be used to collectively
+refer to the PEM_read_bio_foobar(), PEM_read_foobar(),
+PEM_write_bio_foobar() and PEM_write_foobar() functions.
+
+The B<PrivateKey> functions read or write a private key in
+PEM format using an EVP_PKEY structure. The write routines use
+"traditional" private key format and can handle both RSA and DSA
+private keys. The read functions can additionally transparently
+handle PKCS#8 format encrypted and unencrypted keys too.
+
+PEM_write_bio_PKCS8PrivateKey() and PEM_write_PKCS8PrivateKey()
+write a private key in an EVP_PKEY structure in PKCS#8
+EncryptedPrivateKeyInfo format using PKCS#5 v2.0 password based encryption
+algorithms. The B<cipher> argument specifies the encryption algoritm to
+use: unlike all other PEM routines the encryption is applied at the
+PKCS#8 level and not in the PEM headers. If B<cipher> is NULL then no
+encryption is used and a PKCS#8 PrivateKeyInfo structure is used instead.
+
+PEM_write_bio_PKCS8PrivateKey_nid() and PEM_write_PKCS8PrivateKey_nid()
+also write out a private key as a PKCS#8 EncryptedPrivateKeyInfo however
+it uses PKCS#5 v1.5 or PKCS#12 encryption algorithms instead. The algorithm
+to use is specified in the B<nid> parameter and should be the NID of the
+corresponding OBJECT IDENTIFIER (see NOTES section).
+
+The B<PUBKEY> functions process a public key using an EVP_PKEY
+structure. The public key is encoded as a SubjectPublicKeyInfo
+structure.
+
+The B<RSAPrivateKey> functions process an RSA private key using an
+RSA structure. It handles the same formats as the B<PrivateKey>
+functions but an error occurs if the private key is not RSA.
+
+The B<RSAPublicKey> functions process an RSA public key using an
+RSA structure. The public key is encoded using a PKCS#1 RSAPublicKey
+structure.
+
+The B<RSA_PUBKEY> functions also process an RSA public key using
+an RSA structure. However the public key is encoded using a
+SubjectPublicKeyInfo structure and an error occurs if the public
+key is not RSA.
+
+The B<DSAPrivateKey> functions process a DSA private key using a
+DSA structure. It handles the same formats as the B<PrivateKey>
+functions but an error occurs if the private key is not DSA.
+
+The B<DSA_PUBKEY> functions process a DSA public key using
+a DSA structure. The public key is encoded using a
+SubjectPublicKeyInfo structure and an error occurs if the public
+key is not DSA.
+
+The B<DSAparams> functions process DSA parameters using a DSA
+structure. The parameters are encoded using a foobar structure.
+
+The B<DHparams> functions process DH parameters using a DH
+structure. The parameters are encoded using a PKCS#3 DHparameter
+structure.
+
+The B<X509> functions process an X509 certificate using an X509
+structure. They will also process a trusted X509 certificate but
+any trust settings are discarded.
+
+The B<X509_AUX> functions process a trusted X509 certificate using
+an X509 structure. 
+
+The B<X509_REQ> and B<X509_REQ_NEW> functions process a PKCS#10
+certificate request using an X509_REQ structure. The B<X509_REQ>
+write functions use B<CERTIFICATE REQUEST> in the header whereas
+the B<X509_REQ_NEW> functions use B<NEW CERTIFICATE REQUEST>
+(as required by some CAs). The B<X509_REQ> read functions will
+handle either form so there are no B<X509_REQ_NEW> read functions.
+
+The B<X509_CRL> functions process an X509 CRL using an X509_CRL
+structure.
+
+The B<PKCS7> functions process a PKCS#7 ContentInfo using a PKCS7
+structure.
+
+The B<NETSCAPE_CERT_SEQUENCE> functions process a Netscape Certificate
+Sequence using a NETSCAPE_CERT_SEQUENCE structure.
+
+=head1 PEM FUNCTION ARGUMENTS
+
+The PEM functions have many common arguments.
+
+The B<bp> BIO parameter (if present) specifies the BIO to read from
+or write to.
+
+The B<fp> FILE parameter (if present) specifies the FILE pointer to
+read from or write to.
+
+The PEM read functions all take an argument B<TYPE **x> and return
