OpenSSH Keys: A Walkthrough
<i>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.</i><p>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?
