Description

SSHKeyGenParsePublicKey fails with OpenSSH_4.3, shipped with CentOS 5.

This is because as per the Windows check in the method, OpenSSH 4…3 also does not output the key type, therefore there are only 3 fields returned and the check fails.

Therefore adding any key fails, making SSH useless.
