RussianHow do you compile your project? It seems you did not link crypto++ library. If you are using gcc you can add -lcrypto++ to compile options.
Crypto++ errors on creating cipher text
Вопрос
I am pretty new to C++ and I need to use Crypto++. I have been looking for examples that explain how to use it. I found this Example of AES using Crypto++ . And I think this is great... the only thing is when I try to build it, I get a bunch of errors!
First off, I had to change the include path for the header files. I am not sure why, but when I didn't add the "crypto++" in front of the path, it could not find the header files. Another post suggested to use it and it seems to make the errors go away.
In case you want to see the code I am trying to build, it is here:
#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;
}
These are the errors I get

I tried putting in the lines 1 at a time, then building and it seems to start getting errors at creating the cipher text.
