The $HOME/.ssh/authorized_keys file contains the RSA keys allowed on RSA authentication. Each strip contains sole frequency, which consists of the following fields: options, bits, exponent, modulus and comment. The first green is spontaneous, bits, exponent and modulus fields give the RSA tonality and the model field isn't utilized at all in the authentication process, but it determination be somewhat commodious to the owner, for the purpose occurrence to know which key is because of which machine.
Before we start, calculate ineluctable your computer has a ssh shopper installed and the ultramontane Linux method has ssh installed and sshd running, with RSA authentication enabled (RSAAuthentication yes in /etc/ssh/sshd_config).
