    In both PublicKeyInfo and PrivateKeyInfo, the EC public key is a byte
    string that is encoded as a bit string. This class adds convenience
    methods for converting to and from the byte string to a pair of integers
    that are the X and Y coordinates.

        Creates a fingerprint that can be compared with a public key to see if
