Password and password encryption rules of the Discuz forum, and discuz Forum encryption rules Discuz password encryption rules: Md5 (md5 ('string'). 'fixed string '); Fixed strings are randomly generated when users are registered and stored in the salt Field of the data table pre_ucenter_members. For example, if the password is 123456789 and the fixed string

Php-based complete php code encryption and decryption instance, php encryption and decryption This article describes the php code encryption and decryption class based on php. We will share this with you for your reference. The details are as follows: Php code encryption class. You can modify it according to your needs

This article mainly introduces the Practical PHP shared encryption class with public key. this class achieves different encryption results each time, but there is no problem with decryption. it is a very practical encryption class, for more information, see WEB interaction security, which has always been the primary solution for all major websites. The PHP

Php rsa encryption and decryption methods and development interfaces, rsa encryption and decryption Network security is very important, especially to ensure data security. Many programmers who write interfaces directly transmit plaintext data. In my opinion, this is not professional. I advocate that all data through interfaces should be encrypted and decrypted before use. This article mainly introduces the

Now PHP encryption methods have a lot of general, the general simple encryption method is directly MD5, but MD5 some simple password can also be decompile, so we now through the custom method to encrypt more secure. Now is I collect and summarize some methods of PHP encryption method, share for everyone, for your reference. Method One: /*** Encrypt user's passwo

Php implements source code encryption, and php source code encryption. Php implements source code encryption. this example describes how php implements source code encryption. Share it with you for your reference. The specific implementation method is as follows: phpfun php implements source code

In the development of the project, some data needs to be encrypted and the server verifies that the request is made by our client!Scenarios are server-determined, using HmacSHA1 encryption and MD5 BASE64 encryptionThe encryption process is more complex1. Get GMT2. Use base64 encoding to calculate the MD5 value of the requested data content3. Set the request format4. Set the authentication information, need

PHP implements DES encryption and decryption instance code, and phpdes encrypts and decrypts instances. PHP-implemented DES encryption and decryption instance code. phpdes encryption and decryption instance this article describes the PHP-implemented DES encryption and decryption instance. For your reference, the code o

Mobile phone typing is really troublesome, so I will not directly provide instances for some simple or too complex code. 1. Not a method-add commentsAdd unnecessary comments without signature. Code omitted 2. case-insensitive Mixing Ignore case sensitivity using VBS 3. Mixing branches and peers Use the colon (:) to connect multiple lines of code as one line 4.

Comments: Common encryption algorithms include symmetric encryption algorithms, asymmetric encryption algorithms, and Hash algorithms. Symmetric encryption is an encryption algorithm that uses the same key for encryption and decry

Http://www.cnblogs.com/1-2-3/archive/2007/09/17/colloquialism-digital-certificate-part1.htmlSummaryThis series is easy to read, so you can understand the basic principles of digital signatures and how to apply them (even if you are an enterprise boss who is not computer savvy, you can read this article). Then we step into the technical details, and finally will give a B/s information system using the digital signature demo.Because the digital signature is based on asymmetric

Objective: Recently accidentally and colleagues to exchange data security transmission problems, think of their own used RSA asymmetric encryption algorithm, idle down to sum up. Several other encryption methods: RSA encryption of Android data encryptionAES encryption of Android data encryptionDes
