man ssh-keygen
====
   ssh-keygen generates, manages and converts authentication keys for ssh(1).  ssh-keygen can create RSA keys for use by SSH
   protocol version 1 and RSA or DSA keys for use by SSH protocol version 2.  The type of key to be generated is specified with
   the -t option.

FILES
   $HOME/.ssh/identity
         Contains the protocol version 1 RSA authentication identity of the user.  This file should not be readable by anyone
         but the user.  It is possible to specify a passphrase when generating the key; that passphrase will be used to
         encrypt the private part of this file using 3DES.  This file is not automatically accessed by ssh-keygen but it is
         offered as the default file for the private key.  ssh(1) will read this file when a login attempt is made.

   $HOME/.ssh/identity.pub
         Contains the protocol version 1 RSA public key for authentication.  The contents of this file should be added to
         $HOME/.ssh/authorized_keys on all machines where the user wishes to log in using RSA authentication.  There is no
         need to keep the contents of this file secret.

   $HOME/.ssh/id_dsa
         Contains the protocol version 2 DSA authentication identity of the user.  This file should not be readable by anyone
         but the user.  It is possible to specify a passphrase when generating the key; that passphrase will be used to
         encrypt the private part of this file using 3DES.  This file is not automatically accessed by ssh-keygen but it is
         offered as the default file for the private key.  ssh(1) will read this file when a login attempt is made.

   $HOME/.ssh/id_dsa.pub
         Contains the protocol version 2 DSA public key for authentication.  The contents of this file should be added to
         $HOME/.ssh/authorized_keys on all machines where the user wishes to log in using public key authentication.  There
         is no need to keep the contents of this file secret.

   $HOME/.ssh/id_rsa
         Contains the protocol version 2 RSA authentication identity of the user.  This file should not be readable by anyone
         but the user.  It is possible to specify a passphrase when generating the key; that passphrase will be used to
         encrypt the private part of this file using 3DES.  This file is not automatically accessed by ssh-keygen but it is
         offered as the default file for the private key.  ssh(1) will read this file when a login attempt is made.

   $HOME/.ssh/id_rsa.pub
         Contains the protocol version 2 RSA public key for authentication.  The contents of this file should be added to
         $HOME/.ssh/authorized_keys on all machines where the user wishes to log in using public key authentication.  There
         is no need to keep the contents of this file secret.

   /etc/moduli
         Contains Diffie-Hellman groups used for DH-GEX.  The file format is described in moduli(5).
