数据库的密码是根据填入的字符串 生成的32位MD5码。 现在要读取出来密码 并修改密码。
问题就是：怎么讲32位的MD5码还原成原来的String字符串。。
有会的吗 谢谢、、、

It’s impossible to even think about it with your toes, because no matter how long the string is, it will always be 16 bits after MD5. (32 bits is because the first eight bits and the last eight bits are checksums).
