The $HOME/.ssh/authorized_keys classify contains the RSA keys allowed after RSA authentication. Each stock contains sole guide, which consists of the following fields: options, bits, exponent, modulus and comment. The maiden green is non-requisite, bits, exponent and modulus fields give the RSA key and the last field isn't used at all in the authentication process, but it wishes be somewhat useful to the owner, for the purpose instance to be acquainted with which pivotal is in place of which machine.
