带恢复功能的 BouncyCastle RSA 概率签名方案

Question

以下代码带有recovery签名消息，如何用C#BouncyCastle实现？

std::vector<unsigned char> data{ 1,2,3,4,5,6 };

CryptoPP::AutoSeededRandomPool rng;
CryptoPP::InvertibleRSAFunction params;
params.GenerateRandomWithKeySize(rng, 2048);

CryptoPP::RSA::PrivateKey privateKey(params);
CryptoPP::RSA::PublicKey publicKey(params);
CryptoPP::RSASS<CryptoPP::PSSR, CryptoPP::SHA1>::Signer signer(privateKey);

CryptoPP::SecByteBlock signature(signer.MaxSignatureLength(data.size()));

unsigned long signatureLen = signer.SignMessageWithRecovery(rng, &data[0],
    data.size(), NULL, 0, signature);

std::vector<unsigned char> encrypted;
encrypted.assign(signatureLen, 0);
memcpy(&encrypted[0], signature.m_ptr, signatureLen);

Answer 1

我认为 Iso9796d2PssSigner class in the Org.BouncyCastle.Crypto.Signers 命名空间应该可以满足您的需求。您可以在 ISO9796Test.cs.
