RSA is not vulnerable, but the source of entropy is the weakest link in the RSA algorithm. The problem with RSA is its source of randomness. RSA: This non-elliptic crypto algorithm which is based on prime numbers generates a relatively insecure key pair when you pick a key size below 2048-bits. DSA key pairs should not be used anymore. OpenSSH version 7.0 and newer even refuse DSA keys smaller than 1024-bits. Let's go over these public-key algorithms:ĭSA: This algorithm is deprecated due to very poor randomness. SSH can generate DSA, RSA, ECDSA and Ed25519 key pairs. Herclues tangles Kerberos, Gravure Sebald Beham 1540 Technical overview

This blog post will explain how to master the SSH deamon, just as how Hercules tained the wild three-headed Kerberos beast. It is up to you to configure your SSH daemon in a secure manner. Passwords should be avoided when possible because they are predictable and unavoidably weak. The most important reason to choose public key authentication over password authentication is to defeat feasible brute-force attacks. However, not all SSH sessions are created equal. SSHD (Secure SHell Daemon) is the server-side program for secure remote connections cross-platform developed by none other than the OpenBSD team.
