Apache Commons Crypto

Apache Commons Crypto 是一个加密库，使用 AES-NI (Advanced Encryption Standard New Instructions) 进行优化。提供了加密级别和流级别的 API。开发者可以使用最少代码来实现高性能的 AES 加解密应用。Maven：<dependency>

//Creates a CryptoCipher instance with the transformation and properties.
CryptoCipher cipher = Utils.getCipherInstance(CipherTransformation.AES_CTR_NOPADDING, properties);

String input = "hello world!";
int inputOffset = 0;
int inputLen = input.length();
byte[] output = new byte[1024];
int outputOffset = 0;
//Initializes the cipher with ENCRYPT_MODE, key and iv.
cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(key,"AES"), new IvParameterSpec(iv));
//Continues a multiple-part encryption/decryption operation for byte array.
cipher.update(input.getBytes("UTF-8"), inputOffset, inputLen, output, outputOffset);
//We should call do final at the end of encryption/decryption.
cipher.doFinal(inBuffer, outBuffer);
//Closes the cipher.
cipher.close();
