C++ AES(Advanced Encryption Standard) implementation

This class is very simple to use:

...
unsigned char plain[] = { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff }; //plaintext example
unsigned char key[] = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f }; //key example
unsigned int plainLen = 16 * sizeof(unsigned char);  //bytes in plaintext

AES aes(AESKeyLength::AES_128);  // 128 - key length, can be 128, 192 or 256
c = aes.EncryptECB(plain, plainLen, key);
// now variable c contains plainLen bytes - ciphertext
...
delete[] c;

Or for vectors:

...
vector<unsigned char> plain = { 0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff }; //plaintext example
vector<unsigned char> key = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f }; //key example

AES aes(AESKeyLength::AES_128);
c = aes.EncryptECB(plain, key);
// now vector c contains ciphertext
...

ECB, CBC, CFB modes are supported.

• This library does not provide any padding. Plaintext and ciphertext length in bytes must be divisible by 16. If length doesn't satisfy this condition exception will be thrown. You can use any padding before encryption if necessary
• This library does not provide any key derivation function. Key length must 128/192/256 bits respectively. You can use any KDF before encryption if necessary
