The document discusses two formats for SSH public keys: the standard format and the one-line format. 1. **Standard Format**: Required by some SSH servers, it includes a header and footer, along with a comment. An example is provided, showing the structure with lines starting with "-----BEGIN SSH2 PUBLIC KEY-----" and ending with "-----END SSH2 PUBLIC KEY-----". 2. **One-Line Format**: Needed for OpenSSH servers, this format is used when copying the public key into the `authorized_keys` file. It is a single line that starts with "ssh-rsa" followed by the key data and an optional comment. The document emphasizes the importance of using the correct format based on the server requirements.
