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.
