php使用openssl_encrypt、openssl_decrypt封装AES，目前有：
aes-256-cbc,
aes-192-cbc,
aes-128-cbc,
aes-256-ecb,
aes-192-ecb,
aes-128-ecb,
aes-256-cfb,
aes-192-cfb,
aes-128-cfb,
aes-256-cfb1,
aes-192-cfb1,
aes-128-cfb1,
aes-256-cfb8,
aes-192-cfb8,
aes-128-cfb8。
后续有时间再添加。
可以访问我在gitee.com上面的接： https://gitee.com/fang_wen_feng/my_php_plugCode/blob/phpcode/phpCode/Aes01.php
