AESCryptor is a C++ class that provides AES encryption and decryption functionalities using the CommonCrypto library. It supports AES-256 encryption and uses PKCS#7 padding.
- C++ Compiler supporting C++11 or higher
- macOS or iOS development environment (CommonCrypto is part of these platforms)
#include <CommonCrypto/CommonCrypto.h>
#include <string>
#include <iostream>
#include "AES.h"
int main() {
std::string key = "0123456789abcdef0123456789abcdef"; // 32 bytes for AES-256
std::string iv = "0123456789abcdef"; // 16 bytes
try {
AESCryptor cryptor(key, iv);
std::string plaintext = "Hello, World!";
std::string encryptedHex = cryptor.EncryptHex(plaintext);
std::string decrypted = cryptor.DecryptHex(encryptedHex);
std::cout << "Plaintext: " << plaintext << std::endl;
std::cout << "Encrypted (Hex): " << encryptedHex << std::endl;
std::cout << "Decrypted: " << decrypted << std::endl;
} catch (const std::exception& e) {
std::cerr << "Error: " << e.what() << std::endl;
}
return 0;
}Plaintext: Hello, World!
Encrypted (Hex): 4AF6287D964F3BF6301684747A381A75
Decrypted: Hello, World!
For macOS and iOS applications, AESCryptor supports NSString* encryption and decryption.
Ensure that the key and IV lengths are appropriate for AES-256 (key: 32 bytes, IV: 16 bytes).
