It is possible to store SSH private keys in gpg-agent, which uses the openpgp-s2k3-sha1-aes-cbc algo to encrypt the key for storage. s2k3 is an iterated-and-salted s2k algorithm from RFC2440, the protected private key format is: https://gitorious.org/gnupg-org/gnupg/blobs/master/agent/keyformat.txt https://gitorious.org/gnupg-org/gnupg/blobs/master/agent/key... The number of iterations is at least 65536, whereas with pkcs8 openssl uses 2048 iterations by default.
