Command Usage
◆
If no parameters are entered, all keys are displayed. If the user keyword is
entered, but no user name is specified, then the public keys for all users
are displayed.
◆
When an RSA key is displayed, the first field indicates the size of the host
key (e.g., 1024), the second field is the encoded public exponent (e.g.,
35), and the last string is the encoded modulus. When a DSA key is
displayed, the first field indicates that the encryption method used by SSH
is based on the Digital Signature Standard (DSS), and the last string is the
encoded modulus.
