我是 C++ 的新手，我需要使用 Crypto++。我一直在寻找解释如何使用它的示例。我找到了这个 Example of AES using Crypto++ .我认为这很棒……唯一的问题是当我尝试构建它时，我遇到了一堆错误!
首先，我必须更改头文件的包含路径。我不知道为什么，但是当我没有在路径前添加“crypto++”时，它找不到头文件。另一篇帖子建议使用它，它似乎可以消除错误。
如果您想查看我正在尝试构建的代码，它在此处:
#include <iostream>
#include <string>
#include <iomanip>
#include "crypto++/modes.h"
#include "crypto++/aes.h"
#include "crypto++/filters.h"
using namespace std;
int main(int argc, char* argv[]) {
//
// Key and IV setup
//AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-
//bit). This key is secretly exchanged between two parties before communication
//begins. DEFAULT_KEYLENGTH= 16 bytes
byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );
//
// String and Sink setup
//
string plaintext = "Now is the time for all good men to come to the aide...";
string ciphertext;
string decryptedtext;
//
// Dump Plain Text
//
cout << "Plain Text (" << plaintext.size() << " bytes)" << endl;
cout << plaintext;
cout << endl << endl;
// //
// // Create Cipher Text
// //
CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );
CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() + 1 );
stfEncryptor.MessageEnd();
//
// Dump Cipher Text
//
cout << "Cipher Text (" << ciphertext.size() << " bytes)" << endl;
for( int i = 0; i < ciphertext.size(); i++ ) {
cout << "0x" << hex << (0xFF & static_cast<byte>(ciphertext[i])) << " ";
}
cout << endl << endl;
//
// Decrypt
//
CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );
CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
stfDecryptor.MessageEnd();
//
// Dump Decrypted Text
//
cout << "Decrypted Text: " << endl;
cout << decryptedtext;
cout << endl << endl;
return 0;
}
这些是我得到的错误

我尝试一次输入第 1 行，然后进行构建，但似乎在创建密文时开始出现错误。
最佳答案
你如何编译你的项目？看来您没有链接 crypto++ 库。如果您使用的是 gcc，则可以将 -lcrypto++ 添加到编译选项。
关于c++ - 创建密文时出现 Crypto++ 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22918831/
