pub
What is a .pub file?
text/plain
A .pub file holds an SSH public key in the single-line OpenSSH format. An algorithm name (such as ssh-ed25519), a Base64-encoded key blob, and an optional comment. It is the shareable half of an SSH key pair, added to a server's authorized_keys to grant access.
How to use a .pub file
Use an example .pub to test SSH public-key parsers, authorized_keys tooling, and key-format converters, or to verify fingerprint computation. Sample key material only.

- SSH Public Key (Ed25519)An OpenSSH-format Ed25519 public key (the shareable half of the key pair): a single line of algorithm, Base64 key blob, and comment, for testing SSH public-key parsers and authorized_keys tooling.
- SSH Ed25519 Public Key: SAMPLEOpenSSH-format SAMPLE Ed25519 public key for authorized_keys and SSH parsers.
- SAMPLE OpenSSH Public Key: RSAThe SAMPLE leaf's RSA key in single-line OpenSSH format with a comment: the same key material as the PEM public keys, wrapped the way authorized_keys wants it. Handy for checking that a fingerprint tool agrees across encodings.
- SAMPLE OpenSSH Public Key: ECDSA P-256The P-256 public key in OpenSSH form, whose blob names the curve twice, once in the key type and once inside the payload. Parsers that read only one of the two mis-handle mismatched keys.
