Question

我有解密openssl aes加密文本的问题。

以下代码块显示了我如何加密文本。通过CLI，我发送一个托管字符串进行加密，并为此提供密钥。当我使用我用来加密同一个功能的密钥时，它工作得非常好。当我在同一函数中查看dec_out时，解密后的值与输入相同。

但是当我将encryptedtext发送到另一个函数时，它不起作用。在这里你可以看到解密功能。我使用相同的托管密钥加密后，从第一个函数调用它。

const int keyLength = 256;
String^ cryptoLib::CLIWrapper::encrypt(String^ text, String^ key)
{

std::string unmanagedText = msclr::interop::marshal_as<std::string>(text);
std::string unmanagedKey = msclr::interop::marshal_as<std::string>(key);
const unsigned char* inputArray = (unsigned char*)(unmanagedText.c_str());
const unsigned char* keyArray = (unsigned char*)(unmanagedKey.c_str());
size_t inputLength = unmanagedText.length();

const size_t encslength = ((inputLength + AES_BLOCK_SIZE) / AES_BLOCK_SIZE) * AES_BLOCK_SIZE;
unsigned char *enc_out = (unsigned char*)malloc(sizeof(unsigned char) *encslength);
unsigned char *dec_out = (unsigned char*)malloc(sizeof(unsigned char) *encslength);
memset(enc_out, 0, sizeof(encslength));
memset(dec_out, 0, sizeof(dec_out));

AES_KEY  dec_key, enc_key;
AES_set_encrypt_key(keyArray, keyLength, &enc_key);
AES_encrypt(inputArray, enc_out, &enc_key);
//Decrypt in same function works!
AES_set_decrypt_key(keyArray, keyLength, &dec_key);
AES_decrypt(enc_out, dec_out, &dec_key);
//test in other function
decrypt("", key, enc_out, encslength, inputLength);
std::string output = std::string(reinterpret_cast<const char*>(dec_out));
String^ returnValue = msclr::interop::marshal_as<String^>(output);



return returnValue;
}

任何人都可以帮我解决我的错误吗？
