This class is originally defined in the OpenSSL module. As needed, methods have been added to it by the Net::SSH module for convenience in dealing with SSH functionality.

valid?()

Determines whether the pub_key for this key is valid. (This algorithm lifted more-or-less directly from OpenSSH, dh.c, dh_pub_is_valid.)
