An overview of algorithms
The full name of MD5 is message-digest algorithm 5 (Information-Digest algorithm), in the early 90 by MIT Laboratory for Computer and RSA Data Security Inc, Ronald L. Riv EST developed and developed by MD2, MD3 and MD4.
When managing the internal accounts and passwords of SQL Server, it's easy to assume that all of this is fairly secure. But that is not the case. Here, we list some very dangerous judgments for SQL Server passwords.

Judging from the current network security, the most attention and contact with the most Web page vulnerability should be ASP, in this respect, small bamboo is an expert, I have no say. However, in PHP, there are also serious security issues, but

Any machine will have physical limitations: memory capacity, hard disk capacity, processor speed, etc., we need to make trade-offs between the limitations and performance of these hardware, such as memory read faster than the hard disk, so the

routing table
There are routing table fib_table_hash and routing cache table rt_hash_table in the kernel. The Routing cache table is primarily designed to speed up routing lookups, and each routing query first finds the routing cache and then finds
One of the things that I personally found frustrating with classic ASP is the difficulty associated with completing many Common web-related tasks. For example, the need to allow web visitors to upload files to the Web server was fairly common for
Oracle's documentation describes that when the sample statement is not included, you can use hint to specify the execution plan, which in fact takes effect even if the sample statement is included. Hint

Today, I met the problem and studied it. To solve this problem, we must first understand some of the mechanism of the session. Session in the server is in the form of a hash table, we all know that sessions are conversational level, each user access
