Given elliptic curve parameters, a signature verification procedure is generated that checks a signature given the public key P of the signer, the original message and the signature.

The message is a number and the signature is a pair of two numbers.

For practical applications, you should convert some message digest into a number with the same bit length as the base point order of the elliptic curve and pass it as the message argument.
