SSH, or Secure Shell, is a network protocol used to securely connect to remote systems. SSH uses key pairs consisting of a private and public key to authenticate users without sending passwords over the network.
$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/keydecryptor/.ssh/id_rsa): Created directory '/home/keydecryptor/.ssh'.
Enter passphrase (empty for no passphrase): mypassword Enter same passphrase again: mypassword Your identification has been saved in /home/keydecryptor/.ssh/id_rsa. Your public key has been saved in /home/keydecryptor/.ssh/id_rsa.pub.
Input:
id_rsa (SSH private key file)
Output:
$sshng$1$16$...$...$... (John the Ripper compatible hash)
