) bits. We'd advise always using it with 521 bits, since the keys are still compact and probably safer in comparison to the more compact keys (even though they must be Risk-free also). Most SSH clients now guidance this algorithm.
Then it asks to enter a passphrase. The passphrase is used for encrypting The true secret, in order that it can not be used whether or not another person obtains the non-public crucial file.
