Simple sha1 encryption function example implemented by PHP and phpsha1 encryption example This example describes the sha1 encryption function implemented by PHP. We will share this with you for your reference. The details are as follows: function encryptTokey($data){ $apikey = 'testapikey111'; $ps1 = sha1($apikey . strtolower($data)); $ps1 = strtouppe

label: des style uses the SP data on BS size algorithm 1. symmetric encryption-key encryptionDesIdeaAESFeatures: Public algorithms, low computing workload, fast encryption speed, and high encryption efficiency,Insufficient: insecurePrinciple: in symmetric encryption algorithms, only one key is used. Both parties use th

First, prefaceWith the broadcast technology hot, all the Live app, the early live app's various request protocol parameter information did not do any encryption measures, but slowly someone began to use the back door began to brush powder attention tool, you can make a new small Hua Dan minute into the net red. So somewhere in this problem, the live app starts encrypting the network request parameters. So that is the focus of this article analysis. Th

reducing the effect of anti-compiler processing class files. However, it is not difficult to modify the anti-compiler so that it can process these fuzzy-processed class files. Therefore, we cannot simply rely on Fuzzy Technology to ensure source code security. We can use popular encryption tools to encrypt applications, such as PGP (pretty good privacy) or GPG (GNU Privacy Guard ). In this case, the end us

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
