Hashing Algorithm In C

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...

A year later, in 1991, Rivest developed a more technologically sophisticated MD5 algorithm. It adds the concept of "security-straps" (safety-belts) on the basis of MD4. Although MD5 is slightly slower than MD4, it is safer. This algorithm is clearly composed of four and MD4 designs with a few different steps. In the MD5 algorithm, the size of the information-digest and the necessary conditions for filling are identical to the MD4. Den Boer and Bosselaers have discovered the MD5 algorithm in the fake ...

Overview How to deal with high concurrency, large traffic? How to ensure data security and database throughput? How do I make data table changes under massive data? Doubanfs and DOUBANDB characteristics and technology implementation? During the QConBeijing2009, the Infoq Chinese station was fortunate enough to interview Hong Qiangning and discuss related topics. Personal Profile Hong Qiangning, graduated from Tsinghua University in 2002, is currently the chief architect of Beijing Watercress Interactive Technology Co., Ltd. Hong Qiangning and his technical team are committed to using technology to improve people's culture and quality of life ...

The AJAX-based attacks described in the previous article have many questions, such as not being able to cross domains and lighten the burden. Ajax is delivered through simple get and post, using Httpdebugger, fetching data, and then using the following scenario, 　　By the way, write an example of the attack code. More than the traditional webform, we are more likely to construct some, in fact, for WebForm and Ajax processing and contract process is the same, Ajax data volume relatively small, faster. Combine Sharppcap and Httpwebr ...
