    I'm not sure if you mean, programmatically how you would write code to
    do it, or as an admin is there an easy way to do it. In any case, the
    ssh-keygen tool in openssh does it via:

    ssh-keygen -i -f /path/to/keyfile

    From the man page:

         -i This option will read an unencrypted private (or public)
    key file
                 in SSH2-compatible format and print an OpenSSH compatible
    private
                 (or public) key to stdout. ssh-keygen also reads the
    `SECSH
                 Public Key File Format'. This option allows importing keys
    from
                 several commercial SSH implementations.

    So, from the 'as an admin' perspective, you could probably build a
    script around the exit status from such a command. From the
    programmatic perspective, the openssh code would presumably be a good
    place to look.

    Hope that helps.
    Mark
