Command Usage
â—† 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.
â—† 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.
