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】

     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
