【PHP】 hash加密

之前对密码进行加密是在JS文件里做的，但是不行，改到PHP文件里进行加密比较安全，于是乎……

【原JS加密代码】

var password = sha256_digest(pwd);

后来在网上调查方法，见附，就把php代码改成了下面这个样子，就好用了

【PHP】

$p = $_POST["password"];
$password = hash('sha256',$p);

附【参考】

<?php
$string='password';
echo hash('md5',$string);//新的hash函数，第一个参数指定算法名称
?>
hash支持的加密算法有：
   [0] => md4
   [1] => md5
   [2] => sha1
   [3] => sha256
   [4] => sha384
   [5] => sha512
   [6] => ripemd128
   [7] => ripemd160
   [8] => whirlpool
   [9] => tiger128,3
   [10] => tiger160,3
   [11] => tiger192,3
   [12] => tiger128,4
   [13] => tiger160,4
   [14] => tiger192,4
   [15] => snefru
   [16] => gost
   [17] => adler32
   [18] => crc32
   [19] => crc32b
   [20] => haval128,3
   [21] => haval160,3
   [22] => haval192,3
   [23] => haval224,3
   [24] => haval256,3
   [25] => haval128,4
   [26] => haval160,4
   [27] => haval192,4
   [28] => haval224,4
   [29] => haval256,4
   [30] => haval128,5
   [31] => haval160,5
   [32] => haval192,5
   [33] => haval224,5
   [34] => haval256,5
