WebDec 3, 2024 · RSA keys need to have a modulus of at least 2048 bits but 3072 or 4096 are better because strictly speaking 2048 bits provides only about 112 "bits of security" while the recommendation is 128. All must use SHA2 and not use SHA1. So, in order: ssh-ed25519. ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521.
