Secure Hash Algorithms (SHA)

wikipedia:Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS).

• SHA-512: Ed25519
• SHA-256
• SHA-3 (2015): SHA-3-224, SHA-3-256, SHA-3-384, and SHA-3-512
• SHA-2 (2001)
• SHA-1 (1995), 160-bit hash function. Deprecated. Disabled in OpenSSH 8.8 (September 2021)
• SHA-0 (1993)

ssh-rsa public key signature algorithm depends on SHA-1
