OpenSSH Public Key Fingerprint

Computes a fingerprint for an OpenSSH-encoded public key.

Source library: cryptography

Overview

This node loads an OpenSSH public key and computes a cryptographic fingerprint (hash) of it. Fingerprints are a compact, human-verifiable way to confirm the identity of a public key, commonly displayed when connecting to an SSH server for the first time.

Parameters

• keyfile: The OpenSSH-encoded public key data, as a BYTESLIKE object.
• hash_algorithm: The hash algorithm to use for the fingerprint.
  • MD5: The traditional, legacy SSH fingerprint format (not recommended for new use).
  • SHA-1: An older standard, considered weak.
  • SHA-256: The modern, recommended standard for SSH key fingerprints.

Outputs

• fingerprint: The computed fingerprint as a BYTESLIKE object.

Additional Considerations

• • MD5 and SHA1 are broken and should not be used for new fingerprints that requires security.
• Always compare fingerprints out-of-band (e.g., by phone or in person) when verifying a remote host's key.
