AES

This project is simple implementation of Advanced Encryption Standard (AES). The purpose here is learning and documenting AES. Project is unit tested and it has 100% test coverage. 128bit, 192bit or 256bit keys are supported as described in AES. Also for string Electronic Code Book method is implemented.

Usage

You can either use Electronic Code Book (ECB) method to encrypt/decrypt strings or directly use AES with 128bit block.

ECB

String plaintext = "Lorem ipsum dolor sit amet...";
String key = "one two nine two";

String cypherText = ElectronicCodeBlock.encrypt(plaintext, key, AESKeyType.AES_128);

Block

byte[] plaintextBlock = HexBin.decode("3243f6a8885a308d313198a2e0370734");
byte[] key = HexBin.decode("2b7e151628aed2a6abf7158809cf4f3c");

byte[] cyphertextBlock = AES.encrypt(plaintextBlock, key, AESKeyType.AES_128);
