Function verifyStrict [src]
Verify the signature against a message and public key using cofactorless verification.
This performs strict verification without cofactor multiplication,
checking the exact equation: [s]B = R + [H(R,A,m)]A
This is more restrictive than the standard verify() method and may reject
specially crafted signatures that would be accepted by cofactored verification.
But it will never reject valid signatures created using the sign() method.
Return IdentityElement or NonCanonical if the public key or signature are not in the expected range,
or SignatureVerificationError if the signature is invalid for the given message and key.
