If the signer's private key is kept secret from attackers, no known forgery attacks work against a properly secured implementation of ECDSA. X9.142 specifies a digital signature algorithm, the ECDSA.

You should be asked if you want to save the ECDSA key fingerprint for the remote host. If that happens, congratulations! You’ve successfully removed that single entry from known_hosts.

The Software ECC is a cryptographic library providing the main ECDSA and ECDH functionalities:- ECDSA key generation; - ECDSA signature and verificati ...
