-t “Sort” This feature specifies the kind of critical to be designed. Normally made use of values are: - rsa for RSA keys - dsa for DSA keys - ecdsa for elliptic curve DSA keys
To do this, we could make use of a Distinctive utility known as ssh-keygen, which is involved Along with the regular OpenSSH suite of applications. By default, this will likely create a 3072 little bit RSA key pair.
