asp.net Brief introductionThe ASP developer always solves the authentication problem on its own, but ASP.net already supports the built-in authentication features. In this article, we'll explain how the two have changed in terms of authentication,

I don't remember where I got a MD5 encryption class, because of the reason for development to use MD5 encryption in WTL, but this class is not directly used in the WTL (in the MFC it was a easy job), so I modified, and write this article, To

This strategy will destroy all the data on the hard drive, make sure to back up the important data on the hard disk before the introduction This strategy is mainly divided into the following several aspects First, make the UEFI to start the win8pe,

Overview The basic process of data encryption is to deal with a certain algorithm for files or data that were originally plaintext. Make it unreadable a piece of code, usually called "ciphertext", so that it can only enter the appropriate key to

Dynamic call WebService, you can not add a Web reference, the line is just need to change the WSDL address on it C # dynamic WebService call interface ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26-27--28 29---3

Interface Alipay's interface call is very inconvenient, just do a package, realize the virtual transaction and physical transactions.There are three projects in the solution as well as NDoc generated documents, simple sequence diagrams: Commonalipay,

MD5 Algorithm Description When I'm writing a MD5 algorithm, I find that there are some inaccuracies in the language descriptions in both English and Chinese, and some details are not clear or obscure. Finally have to come up with C language source

Encryption | data | Database NET provides a class for data encryption, and the following examples illustrate how to use MD5 for data encryption. First, create a UserAccount table, the fields two: username and password, the types are varchar (25)

　What is MD5? MD5 is a hash function widely used in the field of computer security to provide integrity protection for messages. In the 1991, Rivest developed a more sophisticated MD5 algorithm. It adds the concept of "security-straps"

1. Manually modify the password In some cases, we have forgotten the administrator's password. Or site after the attack, the administrator password has been maliciously modified. At this point, all we can do is reset the administrator's password.

The following are specific configurations: PIX version 6.3 (1)//Os I used version 6.3, this version supports IPSec VPN with NAT Interface Ethernet0 Auto Interface Ethernet1 Auto Nameif Ethernet0 outside Security0 Nameif Ethernet1 inside

Safety | design For WEB applications, it is important to secure logins. But most WEB systems are sending plaintext when they send a login password, so it's easy for intruders to hear passwords. Of course, SSL is a good way to implement secure

The torrent file, also known as the seed, was just a file for recording the information needed in the BT download. But with the great development of the Internet, some people have injected some evil information into the small torrent file, and the

It is necessary to maintain state information for Web pages and their controls. However, because Web applications are created at the top level of the HTTP protocol, this is a stateless protocol, so maintaining state information becomes very

For injection, error hints are extremely important. The so-called error tip refers to the correct page and the results of different feedback, the master is very important to this point, which is critical to the accurate evaluation of the injection

For the day IP is not high or the number of concurrent numbers is not a big application, generally do not consider these! There is no problem with the normal file operation method. However, if the concurrency is high, when we read and write to the
