推荐答案

这不是加密，而是加密哈希函数 ，这是非常不同的东西.是的，它足以存储密码.请参见 http://en.wikipedia.org/wiki/Cryptographic_hash_function [ http://en.wikipedia.org/wiki/MD5 [ ^ ].我建议使用安全哈希算法("SHA")系列的功能，请参见 http://en.wikipedia.org/Wiki/SHA2 [ ^ ].

要将密码哈希函数与PHP一起使用，请参见:
http://php.net/manual/en/function.hash.php [ ^ ].

This is not encryption, but a cryptographic hash function, which is a very different thing. Yes, it can be good enough to store passwords. See http://en.wikipedia.org/wiki/Cryptographic_hash_function[^].

A word or warning: don''t use MD5! This algorithm is considered broken, see http://en.wikipedia.org/wiki/MD5[^]. I would recommend to use the functions of the Secure Hash Algorithm ("SHA") family, see http://en.wikipedia.org/wiki/SHA2[^].

To use the cryptographic hash functions with PHP, see:
http://php.net/manual/en/function.hash.php[^].
