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 display the original content, through such a way to protect the data is n

If you save valuable files on your laptop, you certainly know the importance of protecting the data. However, knowing that something should be done does not necessarily mean that it is being done, because a large number of reports every day indicate that sensitive data of many companies is lost or stolen from their laptops. However, protecting data security is no

If you are running a Web application that uses MySQL, it can store passwords or other sensitive information in the application. Protecting this data from access by hackers or prophers is an important concern, because you cannot allow unauthorized users to use or destroy applications, but also ensure your competitive advantage. Fortunately, MySQL comes with a lot of encryption functions designed to provide t
On the principle of data encryption, you can refer to [data security] to talk about the mathematical principles of cryptography http://blog.csdn.net/u010415792/article/details/9007931. How to encrypt the technology from here, in the understanding of specific real-time before, must first understand the principle of public key key, know it, but also know why.

Steganos Safe is a data encryption software from Germany that uses AES encryption algorithms to effectively protect sensitive data. In addition, the encrypted data can be stored on the U-disk mobile device without having to install any programs to open on another computer.So
Data flow is a typical embodiment of object-oriented thinking in object-oriented programming language, it completely replaces the function of input and output by using function, and overcomes many drawbacks of realizing input-output function with function. In a nutshell, a stream is an abstract tool for processing data based on an object-oriented approach. In a stream, you can define some basic operations f
LUA communicates with PHP via AES data encryption
Recently, the company has a "around the nerve cat" small game hot not! The company also decided to develop a series of nerve cat games, so I was pulled over.

In the design of various communication devices and terminal electronic products, more and more embedded systems are used to make the products have more powerful functions, as are WiMAX wireless communication devices. Therefore, when designing and developing security technologies in modern network and communication technologies, they must be integrated with embedded technologies. In this paper, a solution of WiMAX wireless access device encryption te

Summary:Most dynamic Web sites support the transfer of data from the client to the server, which is dangerous if the data being passed is intercepted by others, especially some user name passwords. This is when we need to encrypt the data before passing
