PHPSecLib: A PHP class library designed to achieve extremely strong compatibility effects
The design goal of phpseclib is to achieve extremely strong compatibility. It runs on PHP4 (requires PHP4 if using PHP_Compat) and does not require any other extensions. For users who value speed performance, you can also use mcrypt, gmp and bcmath (in order), but the three are not required.

How to use the filter_var function for validation in PHP?
09 Nov 2025
The filter_var() function is used to verify and clean data. It supports email, integer, URL, IP and other format verification. It is implemented through built-in filters such as FILTER_VALIDATE_EMAIL without the need for external libraries.
Best way to keep unparsed JSON fields in Go
01 Jan 2026
This article discusses how to decode some fields into a structure while retaining other fields not defined in the structure when using the encoding/json package to process JSON data in the Go language. We will introduce methods using the json.RawMessage type and custom Unmarshaler/Marshaler interfaces, and briefly mention solutions from other libraries to help developers flexibly handle dynamic JSON data.

How to Use Async/Await for Asynchronous Programming in Python?
02 Feb 2026
async and await implement collaborative concurrency within a single thread, improving efficiency by pausing I/O waiting coroutines and switching to execute other coroutines; it is necessary to use asynchronous libraries (such as aiohttp), avoid blocking calls, and use asyncio.gather to correctly schedule tasks.
Reagraph's font import strategy for displaying non-Latin characters (such as Russian) in Vite apps
20 Jan 2026
In the Vite project, when using Reagraph to draw graphics and try to display Russian and other non-Latin characters on nodes, the characters often cannot be displayed normally due to a failure to load the font file. The core solution is to declare font module types such as .ttf in the vite-env.d.ts file so that Vite can correctly parse and import these assets, thereby providing the necessary font support for Reagraph or other text rendering libraries.
Strategies and best practices for random number generation in Go libraries
02 Dec 2025
When dealing with random number generation in Go language libraries, initialization and usage strategies need to be carefully chosen to avoid conflicts with the application layer or other libraries, and to ensure that the randomness meets requirements. This article will explore three core methods: implementing dependency injection through interfaces to provide flexibility, utilizing the crypto/rand package to meet high security requirements, and using private rand.Rand instances to isolate internal randomness, aiming to guide developers to choose the most appropriate random number generation scheme based on specific scenarios.
