安全的PHP和Java（Android）加密和解密功能

Question

I'm trying to find a very secure php encryption that can be decrypted in Android and vice-versa to send data securely. I found old functions not compatible with new versions of PHP. Any ideas please?

Encryption and decryption functions are deterministic. If you encrypt SHA-256 on Android, and then decrypt it with PHP, it should work fine. They use the same functionality.

If you have tried this and it didn't work, your problem most likely lies in your encoding method.

Current PHP encryption method: http://php.net/manual/en/function.openssl-encrypt.php
