Interface PHP uses Openssl_encrypt and Android for symmetric encryption

Since the original mcrypt_decrypt has been discarded, and now the encryption of the docking with Android to Openssl_encrypt

PHP encryption key is 32 bits, IV is a 16-digit pure number, the filling mode is 0, the encryption algorithm is as follows

$res = Openssl_encrypt ($data, ' AES-256-CBC ', Self:: $key, 0, Self:: $IV); Need encrypted data, algorithm, key, padding method, IV

The interface directly returns the encrypted string $res

Andrew decrypted the Android decryption method.
