OpenSSH Keys: A Walkthrough
When most people think of SSH keys, they probably think of RSA if they’re aware of the underlying cryptography. Until recently, they would be right: RSA has been a mainstay of public key cryptography for some time now, and although it’s on the way out for new protocols and systems, it will be around for quite some time.Why is RSA on the way out? This is news for me. Are there any (potential) weaknesses that have been discovered recently in the RSA? I know that elliptic curve cryptography has shorter (and hence somewhat more convenient) keys, but that fact alone hardly makes RSA obsolete. Are there anything else?
