process is unidirectional, as shown in.The general purpose of one-way hash encryption is the encryption of the user's password, so that the password is not reversible to the database, even if the database information leaks, the attacker can not know what the original password is.The common one-way hashing algorithm has MD5, SHA and so on.5.2 Symmetric encryptionThat is, both encryption and decryption use the same key, as shown in:The commonly used symmetric encryption algorithm has DES algorith

1. Overview Dr. Roy Fielding (see Personal homepage) is the main designer of the HTTP and URI protocol issued by the IETF. HTTP and Uri are the two most important web infrastructure protocols, so Dr. Fielding is one of the founders of the Web architecture. In addition to academic excellence, Dr. Fielding has been involved in the design and development of many O

Recently just finished reading Hae's "large Web site technology architecture-core Principles and case analysis", the key content of each chapter made some notes, in order to deepen the impression and future review.First, the characteristics of large-scale website software systemhigh concurrency, large flow: need to face high concurrent users, large traffic access. High Availability: system 7x24 Hour service

performance, high availability, scalability, scalability, security and other technical architecture goals. These solutions are re-used by the website, which gradually forms a large web site architecture.2.11 LayeringLayering is one of the most common architectural patterns in enterprise application system, which splits several parts of the system in the horizont

Simple web layer-3 architecture system (3rd edition), web layer-3 Architecture Today is the third edition. As we did a few days ago, we still need to optimize the code. The three-tier architecture is an idea. Whether the overall system security and high performance can be e

Typically, a site's architecture comes with functional requirements, and the following five aspects should be considered:PerformanceAvailability ofElasticity ofScalabilitySecurityThe official explanation of performance performance, I will not say. To the user, is the system reaction speed is fast.For Web sites, performance issues are ubiquitous, and then there are a number of ways we can optimize performanc

Extensibility: The ability of system functions to be continuously expanded and enhanced in the case of minimal impact to existing systems. Performance in system infrastructure stability does not require frequent changes, less reliance and coupling between applications, and an agile response to demand changes. It is a system architecture design level of open and close principle, architecture design to consid
