from the command reference:
rsa-sig Specifies RSA signatures as the authentication method.
rsa-encr Specifies RSA encrypted nonces as the authentication method.
RSA signatures and RSA encrypted noncesRSA is a public key
cryptographic system RSA signatures provide nonrepudiation, and RSA
encrypted nonces provide repudiation. A nonce is a pseudo-random
number generated to aid in encryption/decryption with a public/private
key. This rsa-encr method is only supported in the Cisco IOS I
believe, not other Cisco devices.
Non-repudiation basically means that the sender wil not be able to
deny that he sent the message, the drawback with nonces is this only,
they do not support non-repudiation which is good for 'integrity'
checking
