- Add key blacklisting support. Keys listed in
/etc/ssh/blacklist. TYPE-LENGTH will be rejected for authentication by
sshd, unless "PermitBlacklistedKeys yes" is set in
/etc/ssh/sshd_ config.
- Add a new program, ssh-vulnkey, which can be used to check keys
against these blacklists.
- Depend on openssh-blacklist.
- Force dependencies on libssl0.9.8 / libcrypto0.9.8-udeb to at least
0.9.8c-4ubuntu0. 3.

critical-priority debconf note. (I regret that there was no time to
gather translations.)
