c++ - 密码++ : CFB_Mode_ExternalCipher not working

Question

这就是代码的样子。这有什么问题吗？恢复文本不匹配。

AES::Encryption aes1(key, key.size());
CFB_Mode_ExternalCipher::Encryption cfbEncryption(aes1, iv);
AES::Decryption aes2(key, key.size());
CFB_Mode_ExternalCipher::Decryption cfbDecryption(aes2, iv);

ArraySink cipherSink(cipher, data_size);
ArraySource ss1(plain, data_size, true, new StreamTransformationFilter(cfbEncryption, new Redirector(cipherSink)));

ArraySink recoverSink(recover, data_size);
ArraySource ss2(cipher, data_size, true, new StreamTransformationFilter(cfbDecryption, new Redirector(recoverSink)));

Answer 1

在转换中使用CTR Mode External Cipher时，加密也用于解密。
