plusaes
Header only C++ AES cipher library.
Development Environment
- Visual Studio 16 2022 (v143)
- Xcode 14.3 (Apple clang 14.0.3)
- GCC 4.8.5 (CentOS 7)
Supported block cipher mode
- ECB
- CBC
- GCM
- CTR
Usage
For example, about AES-CBC 128-bit.
Encrypts by the plusaes::encrypt_cbc and decripts by the plusaes::decrypt_cbc.
You can use convenient functions like plusaes::key_from_string and plusaes::get_padded_encrypted_size.
#include "plusaes/plusaes.hpp"
#include <string>
#include <vector>
int main() {
// AES-CBC 128-bit
// parameters
const std::string raw_data = "Hello, plusaes";
const std::vector<unsigned char> key = plusaes::key_from_string(&"EncryptionKey128"); // 16-char = 128-bit
const unsigned char iv[16] = {
0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F,
};
// encrypt
const unsigned long encrypted_size = plusaes::get_padded_encrypted_size(raw_data.size());
std::vector<unsigned char> encrypted(encrypted_size);
plusaes::encrypt_cbc((unsigned char*)raw_data.data(), raw_data.size(), &key[0], key.size(), &iv, &encrypted[0], encrypted.size(), true);
// fb 7b ae 95 d5 0f c5 6f 43 7d 14 6b 6a 29 15 70
// decrypt
unsigned long padded_size = 0;
std::vector<unsigned char> decrypted(encrypted_size);
plusaes::decrypt_cbc(&encrypted[0], encrypted.size(), &key[0], key.size(), &iv, &decrypted[0], decrypted.size(), &padded_size);
// Hello, plusaes
