篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了js 前端md5加密 后端怎么办相关的知识，希望对你有一定的参考价值。
1、私钥2、加密算法（你去找一个与js加密算法对应php的加密函数，这种加密解密算法一般都是一样的） ！ 参考技术A 烨伟 (烨：光耀) 苑博 (博：博学)

后端
public function encrypt2($input = '')
$pk = "123454536f667445454d537973576562";
$iv = substr("1234577290ABCDEF1264147890ACAE45", 0, 16);
// $t = 'T10515';
$encrypted = ( mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $pk, $input, MCRYPT_MODE_CBC,$iv) );
return base64_encode($encrypted);
public function decrypt2($encrypted)
$pk = "123454536f667445454d537973576562";
$iv = substr("1234577290ABCDEF1264147890ACAE45", 0, 16);
// $t = 'T10515';
// $encrypted = "b7y/JPJFNTfxNVR8H4NNtw==";
return mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $pk, base64_decode($encrypted), MCRYPT_MODE_CBC, $iv);
可以推断， js 部分实际只使用了 iv 的 16 位长度
ps：
js加密后默认会base64_encode
使用php解密需要base64_decode后才一致
所以使用js加密和php解密时候需要注意，php端要先base64_decode再解密，例：
js加密的串是$t=b7y/JPJFNTfxNVR8H4NNtw==
php需要
$password= trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $pk,base64_decode( $t), MCRYPT_MODE_CBC, $iv));
则$password才能正确解析出来
需要引入的两个js文件
