一个第三方加密的java demo，我要使用php加密，看不懂java，求大佬帮忙看看有什么方法用到php
<?php
class AES {
/**
*
* @param string $string 需要加密的字符串
* @param string $key 密钥
* @return string
*/
public static function encrypt($string, $key)
{
$key = substr(openssl_digest(openssl_digest($key, 'sha1', true), 'sha1', true), 0, 16);
$data = openssl_encrypt($string, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
$data = strtoupper(bin2hex($data)); return $data;
}
/**
* @param string $string 需要解密的字符串
* @param string $key 密钥
* @return string
*/
public static function decrypt($string, $key)
{
$key = substr(openssl_digest(openssl_digest($key, 'sha1', true), 'sha1', true), 0, 16);
$decrypted = openssl_decrypt(hex2bin($string), 'AES-128-ECB', $key, OPENSSL_RAW_DATA); return $decrypted;
}
}
?>
