Functions
template<typename Builder , typename Curve , typename Fq , typename Fr , typename G1 >
void	bb::stdlib::validate_inputs (const stdlib::byte_array< Builder > &hashed_message, const G1 &public_key, const ecdsa_signature< Builder > &sig)
	Validate the inputs used by the verification function and return messages if they produce an invalid circuit.
template<typename Builder , typename Curve , typename Fq , typename Fr , typename G1 >
bool_t< Builder >	bb::stdlib::ecdsa_verify_signature (const stdlib::byte_array< Builder > &hashed_message, const G1 &public_key, const ecdsa_signature< Builder > &sig)
	Verify ECDSA signature. Returns bool_t(true/false) depending on whether the signature is valid or not.
template<typename Builder >
void	bb::stdlib::generate_ecdsa_verification_test_circuit (Builder &builder, size_t num_iterations)
	Generate a simple ecdsa verification circuit for testing purposes.
