C++ AES implementation

AES

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
unsigned int outLen = 0;  // out param - bytes in сiphertext

AES aes(128);  //128 - key length, can be 128, 192 or 256
c = aes.EncryptECB(plain, plainLen, key, outLen);
//now variable c contains outLen bytes - ciphertext
...

ECB, CBC, CFB modes are supported.

Development:

1. git clone https://github.com/SergeyBel/AES.git
2. docker-compose build
3. docker-compose up -d
4. docker-compose exec aes bash

There are four executables in bin folder:

• test - run tests
• debug - version for debugging (main code will be taken from dev/main.cpp)
• profile - version for profiling with gprof (main code will be taken from dev/main.cpp)
• release - version with optimization (main code will be taken from dev/main.cpp)

Build commands:

• make all - build all targets
• make build_test - build test target
• make build_debug - build debug target
• make build_profile - build profile target
• make build_release - build release target
• make clean - clean bin directory
