Today, when I used the login control in Asp.net 2005, I used the Asp.net web site management tool. When you are using volume management, security administrators always prompt that the SQL statement cannot be executed. After turning over the SQL

A rainbow table is a type of hashAlgorithmIs a cross-platform password cracking tool that can crack multiple types of passwords, such as MD5 and hash. The performance of NTLM is astonishing. It is powered by NVIDIA Cuda technology on a common PC.

In the development of various application systems, user information is often stored. In many places, user passwords must be stored, and direct storage of user passwords on servers is obviously insecure, this article briefly introduces common MD5
