The seal forms are generally divided into two types: Yangwen and Yinwen, also known as Zhuwen and Baiwen. We use PS software to create a special seal for ourselves. If you want to make a classical seal, please install a seal font in the computer font library first. Okay, let’s learn together! Method/step 1. Open the PS software, click New in the menu bar (shortcut Ctrl+N keys), enter the parameters in the pop-up New dialog box, set the height and width to a square of 400 pixels, select white for the background content items, and select white for the rest. Just leave the default settings and click OK. 2. Double-click the background in the layer panel in the lower right corner, click OK in the pop-up dialog box, unlock the background layer to layer 0. Set the foreground color to R230, G30, B30. This is to imitate the color of the ink pad, there is no guarantee. The background color is white. 3. Select the Rounded Rectangle Tool on the left toolbar, click Path in the options bar below the menu bar, and set the radius to 30 pixels. Hold down the shift key and draw a rounded square on the canvas. 4. Select the brush tool on the left toolbar and set the brush tool to a diameter of 10 pixels and a hardness of 100%. Go to the layers panel and click on the path, right-click on the working path, select Stroke Path, and click OK in the pop-up dialog box. Then right click

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
