javascript - What method does js use to encrypt the data of ajax post and transmit it to php for decryption?
Since I don’t want to transmit plain text when doing ajax post, I want to use js to encrypt a js object into a string or binary string for transmission, but I don’t know how to encrypt it, and this encrypted string needs to be in php Decrypt it on the end, and the decrypted data is preferably a php array. Does anyone have such a need? Do you know how to achieve this?

First of all, crypto-js can solve your problem. Choose a symmetric encryption algorithm (such as AES-256-CBC), use AES + password to encrypt on the PHP side, and use AES + password to decrypt on the js side - but this does not make much sense because your passwords are already expressed in plain text in the js code. .
So if your purpose is to transmit untext, it is recommended that you implement asymmetric encryption from the transport layer. The simplest way is to change the server protocol from HTTP to HTTPs.
You can use an asymmetric encryption algorithm, encrypting with the public key in the browser and decrypting with the private key on the server side. The jsencrypt project supports RSA encryption. You only need to use openssl
to generate a key pair, and then put the public key into the page. PHP can decrypt using the openssl series of functions.
The encrypted and decrypted data are all strings. If you want to get the array, you can create an object in JS, then adjust JSON.stringify
and then encrypt it. What PHP decodes is a JSON string, and you can use the json_decode function to decode it to get an array.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
