示例1: SignatureValidate

bool SignatureValidate(PK_Signer &priv, PK_Verifier &pub, bool thorough = false)
{
	bool pass = true, fail;

	fail = !pub.GetMaterial().Validate(GlobalRNG(), thorough ? 3 : 2) || !priv.GetMaterial().Validate(GlobalRNG(), thorough ? 3 : 2);
	pass = pass && !fail;

	cout << (fail ? "FAILED    " : "passed    ");
	cout << "signature key validation\n";

	const byte *message = (byte *)"test message";
	const int messageLen = 12;

	SecByteBlock signature(priv.MaxSignatureLength());
	size_t signatureLength = priv.SignMessage(GlobalRNG(), message, messageLen, signature);
	fail = !pub.VerifyMessage(message, messageLen, signature, signatureLength);
	pass = pass && !fail;

	cout << (fail ? "FAILED    " : "passed    ");
	cout << "signature and verification\n";

	++signature[0];
	fail = pub.VerifyMessage(message, messageLen, signature, signatureLength);
	pass = pass && !fail;

	cout << (fail ? "FAILED    " : "passed    ");
	cout << "checking invalid signature" << endl;

	if (priv.MaxRecoverableLength() > 0)
	{
		signatureLength = priv.SignMessageWithRecovery(GlobalRNG(), message, messageLen, NULL, 0, signature);
		SecByteBlock recovered(priv.MaxRecoverableLengthFromSignatureLength(signatureLength));
		DecodingResult result = pub.RecoverMessage(recovered, NULL, 0, signature, signatureLength);
		fail = !(result.isValidCoding && result.messageLength == messageLen && memcmp(recovered, message, messageLen) == 0);
		pass = pass && !fail;

		cout << (fail ? "FAILED    " : "passed    ");
		cout << "signature and verification with recovery" << endl;

		++signature[0];
		result = pub.RecoverMessage(recovered, NULL, 0, signature, signatureLength);
		fail = result.isValidCoding;
		pass = pass && !fail;

		cout << (fail ? "FAILED    " : "passed    ");
		cout << "recovery with invalid signature" << endl;
	}

	return pass;
