通过MD5加密后保存，和以往仅仅明文保存相比，MD5加密后的保存信息更加安全，毕竟MD5加密后的信息安全性更高，MD5加密方式也是单向的并不存在任何逆向破解。然而你是否知道MD5也并不是真正安全的，入侵者在获得了MD5加密后的字符串后依然可以通过多种方法破解成明文密码。下面就请各位IT168的读者跟随笔者从实战讨论MD5加密的安全性。



　-MD5 encrypted through preservation, and preservation of the past, compared to only expressly, MD5 encrypted to preserve information more secure, after all, MD5 encrypted information of higher security, MD5 is a one-way encryption method does not exist any reverse break. But do you know MD5 is not really safe, the intruder access to the MD5 encrypted string will still be a number of ways to break through into a cleartext password. Here' s IT168 readers please follow the author from actual combat to discuss the security of MD5 encryption.
