php 加密解密演算法函數，mcrypt_encrypt已經不建議了

Question

官網有警告說：This function has been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.

那麼加密解密用什麼函數呢？

Answer 1

openssl_encrypt
openssl_decrypt

>>> openssl_encrypt("1", "aes-256-cbc", "12312321", 0, "1234123443212345");
=> "x6Zfu2cbtbMDfkt2s/GE2A=="
>>> openssl_decrypt("x6Zfu2cbtbMDfkt2s/GE2A==", "aes-256-cbc", "12312321", 0, "1234123443212345");
