+Specifies the number of bits in the key to create.Minimum is 512 bits. Generally 1024 bits is consid-ered sufficient, and key sizes above that no longerimprove security but make things slower. The defaultis 1024 bits.-cRequests changing the comment in the private and pub-lic key files. This operation is only supported forRSA1 keys. The program will prompt for the file con-taining the private keys, for the passphrase if thekey has one, and for the new comment.-eThis option will read a private or public OpenSSH keyfile and print the key in a SECSH Public Key ! FileFormat to stdout. This option allows exporting keysfor use by several commercial SSH implementations.-f filenameSpecifies the filename of the key file.-iThis option will read an unencrypted private (or pub-lic) key file in SSH2-compatible format and print anOpenSSH compatible private (or public) key to stdout.ssh-keygen also reads the SECSH Public Key ! FileFormat. This option allows importing keys from sev-eral commercial SSH implementations.-lShow fingerprint of specified public key file. Pri-vate RSA1 keys are also supported. For RSA and DSAkeys ssh-keygen tries to find the matching public keyfile and prints its fingerprint.-pRequests changing the passphrase of a private keyfile instead of creating a new private key. The pro-gram will prompt for the file containing the privatekey, for the old passphrase, and twice for the newpassphrase.-qSilence ssh-keygen. Used by /etc/rc when creating a new key.
