PHP and Java Universal AES encryption and decryption algorithm AES refers to the Advanced Encryption Standard (encryption), is the most popular one of the current cryptographic algorithm, in Web application development, especially

AES is a Federation standard for private keys or symmetric encryption. Advanced Encryption Standard in cryptographyEncryption Standard, AES), also known as Rijndael Encryption algorithm. It supports a combination of keys and block sizes of 128,192 and 256.

The AES encryption algorithm in Java is as follows: public static byte[] decrypt(byte[] data, byte[] key) throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException { Security.addProvider(new BouncyCastleProvider()); Cipher cipher = Cipher.getInstance("

) {Throw NewRuntimeException (e); } } }2.
