- I made this class to learn how AES works
- The class should have no errors, but if you find one please open a issue 😄
- Lightweight
- C++11
int main()
{
uint8_t data[16] = { 0x6B, 0xC1, 0xBE, 0xE2, 0x2E, 0x40, 0x9F, 0x96, 0xE9, 0x3D, 0x7E, 0x11, 0x73, 0x93, 0x17, 0x2A };
uint8_t key[16] = { 0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, 0x3C };
uint8_t iv[16] = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F };
AES::AES aes(AES::AES128);
aes.encrypt_cbc(data, 16, key, iv);
}
Output: { 76 49 AB AC 81 19 B2 46 CE E9 8E 9B 12 E9 19 7D
