我最近使用了一个 Python 脚本来加密一个字符串。但无法使用 Crypto++ 在 C++ 中解密它。我刚刚比较了生成的加密字符串,发现它们不一样。有人可以帮忙吗?
这是我的 Python 代码:
key = "0123456789abcdef"
data = "ccccccccccccccccdddddddddddddddd"
iv = "aaaaaaaaaaaaaaaa"
encryptor = AES.new(key, AES.MODE_CBC, iv)
enc = encryptor.encrypt(data)
print enc
这是我的 C++ 代码:
std::string key = "0123456789abcdef";
std::string iv = "aaaaaaaaaaaaaaaa";
std::string plaintext = "ccccccccccccccccdddddddddddddddd";
std::string ciphertext;
std::string decryptedtext;
std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
std::cout << plaintext;
std::cout << std::endl << std::endl;
CryptoPP::AES::Encryption aesEncryption((byte *)key.c_str(), CryptoPP::AES::DEFAULT_KEYLENGTH);
CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, (byte *)iv.c_str() );
CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() + 1 );
stfEncryptor.MessageEnd();
std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;
for( int i = 0; i < ciphertext.size(); i++ ) {
std::cout << "0x" << std::hex << (0xFF & static_cast<byte>(ciphertext[i])) << " ";
}
CryptoPP::AES::Decryption aesDecryption((byte *)key.c_str(), CryptoPP::AES::DEFAULT_KEYLENGTH);
CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, (byte *)iv.c_str() );
CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
stfDecryptor.MessageEnd();
std::cout << "Decrypted Text: " << std::endl;
std::cout << decryptedtext;
std::cout << std::endl << std::endl;
