Specifies the length of the key in bits (default 2048).
-t dsa|rsa
Selects the type of the key. Valid options are dsa (default) and rsa.
-c comment_string
Specifies the key's comment string.
-e file
Edits the specified key. Makes ssh-keygen2 interactive. You can change the key's passphrase or comment.
-p passphrase
Specifies the passphrase used.
-P
Specifies that the key will be saved with an empty passphrase.
-h | -?
Prints a short summary of ssh-keygen2 commands.
-q
Hides the progress indicator.
-1 file
Converts a key from the SSH1 format to the SSH2 format.
-i file
Loads and displays information on file.
-D file
Derives the public key from the private key file.
-B number
Specifies the number base for displaying key information (default 10).
-V
Prints version string and exits.
-r file
Adds entropy from file to the random pool. If file contains 'relatively random' data (i.e. data unpredictable by a potential attacker), the randomness of the pool is increased. Good randomness is essential for the security of the generated keys.
-x file
Converts a private key from the X.509 format to the SSH2 format.
-k file
Converts a PKCS #12 file to an SSH2-format certificate and private key.
-7 file
Extracts certificates from a PKCS #7 file.
-F file
Dumps the fingerprint of the given public key. The fingerprint is given in the Bubble Babble format, which makes the fingerprint look like a string of "real" words (making it easier to pronounce).
