SSH-KEYGEN 2048SSH keys provide a means of identifying you when you connect to an SSH server using public-key cryptosystems and authentication by challenge-response. One of the immediate advantages of this method over the traditional identification with a password is that you can be logged on the server without the need to regularly send your password over the network. Even if someone will listen to your connection, it will not be able to intercept and crack your password, because in fact he never transmitted. Identification using SSH keys provides additional security.
