Comment 5 for bug 983206

** Impact **

When creating an EC2 key with binary or hex characters value ( ie: 0x,0X,0b,0B), results in a traceback:

** Development Fix **

This has been addressed in the development trunk at: https://review.openstack.org/6604 and fixed in quantal.

** Stable Fix **

This has been addressed in the stable/essex tree at: https://review.openstack.org/7244

** Test Case **

Run the following command:

euca-create-key 0xDD8G > tmp.key

it should not get a traceback in the nova-api.log

** Regression Potential **

Minimal, this is a corner case as well.
