php link address hide id

In the process of using PHP for website development, link addresses often contain ID parameters to identify different pages or data. However, this design sometimes has some security risks, for example, users can directly access other users' data through URLs. Therefore, developers need to find ways to hide these IDs to keep user data safe.

1. Why do you need to hide the ID in the link?

1.1 Prevent brute force cracking

If the ID in the website link address is easy to guess, then the attacker can brute force crack the website. They can insert their own ID into the link and gain access to other users' sensitive data. Especially for some important information, such as bank card numbers, passwords, etc., this risk will be more serious.

1.2 Avoid crawler crawling

Some crawler programs can automatically crawl website data. If the ID in the link address is displayed, the crawler will easily identify the link pattern and perform batch processing. Grab. This means that the website will be surrounded by a large amount of useless data, thus affecting the normal use of users.

1.3 Protecting user privacy

Sometimes, the user’s sensitive information may be stored in the link address, such as user name, mobile phone number, etc. If this information can be easily obtained by others, it will threaten the user's privacy security.

2. How to hide the ID in the link address?

2.1 Use a random string instead of the ID

A simple way is to replace the ID with a randomly generated string, such as using a UUID. The advantage of this is that each ID is unique and difficult to guess. At the same time, crawlers cannot crawl these strings, thereby protecting the security of user data.

2.2 Hide ID using encryption algorithm

Developers can use hash algorithm to encrypt ID to generate a string. Then, add this string to the link address, replacing the original ID. When the page loads, the string is converted to the original ID. In this way, even if the attacker obtains the string, he cannot restore the original ID. This method can also effectively prevent URL path exhaustion attacks from occurring.

2.3 Use Session or Cookie to store ID

Developers can store the ID in Session or Cookie, and then make judgments on pages that need to access sensitive data. Although this method is simple, it also has certain risks. For example, cookies may be stolen. In an insecure network environment, this method is not reliable enough.

3. Use third-party libraries

Developers can also use mature PHP libraries, such as Laravel, Yii2, etc., to hide the ID in the link. These frameworks integrate powerful security features to prevent common security threats, such as XSS, CSRF, etc.

4. Precautions

4.1 Use Session and Cookie with caution

Although storing ID in Session or Cookie can prevent URL path exhaustive attacks, if these data are If a malicious attacker steals it, it will cause a more serious security threat. Developers need to ensure that when using Sessions or Cookies, they also have security measures in place.

4.2 Avoid reducing the user experience

Hiding the ID behind the URL may cause the link to be too long and reduce the user experience. Therefore, the link address needs to be optimized to avoid excessively long URLs. At the same time, some feedback information needs to be provided on the page so that users can know the link address of the current page.

4. Summary

Hiding the ID in the link is a very important security measure. When using PHP for website development, developers need to consider it in the design. Although taking these methods will increase the complexity of the code, it will ensure the security of users' information and give users a better user experience. Developers not only need to carefully build a website with a good user experience, but also take into account the security of user information to ensure good security and ease of use of the website.
