mysql怎么加密密码？
最近密码泄露事件很轰动，我是用插入的SQL语句写入mysql的，明文保存密码！新闻说可以密文保存密码？请问密文保存完整的SQL语句是什么？请教，谢谢。
引用MD5(str)
Calculates an MD5 128-bit checksum for the string. The value is returned as a binary string of 32 hex digits, or NULL if the argument was NULL. The return value can, for example, be used as a hash key.
mysql> SELECT MD5(‘testing’);
-> ‘ae2b1fca515949e5d54fb22b8ed95575’
This is the “RSA Data Security, Inc. MD5 Message-Digest Algorithm.”
