Options
-b bits
Specify the number of bits in the key. The minimum is 512, and the default is 1024.
-B
Show the bubblebabble digest (a digest represented as a string that looks like real words) for the private or public keyfile specified with -f.
-c
Change the comment in the private and public keyfiles (for RSA1 keys only).
-C comment
Specify the new comment.
-D reader
Download the RSA public key from the smartcard in reader.

-f file
Specify the filename of the keyfile.
-i
Read an SSH2-compatible unencrypted private or public keyfile and write an OpenSSH-compatible key to standard output. Used to import keys from a commercial SSH.

-p
Change the passphrase for a private keyfile. Prompt for the file, the old passphrase, and twice for the new passphrase.
