Advanced CSRF Protection with RSA

Advanced CSRF Protection with RSA encryption adds an extra layer of security and prevents unauthorized API usage, stale requests and brute-force attempts.
This approach uses RSA asymmetric encryption to verify the integrity of API requests and securely encrypts request metadata like method, URL, and timestamp.
The payload containing the encrypted data in the custom header is decrypted on the backend.
If the validation passes, only then the API request is processed, or else the request is rejected.
The article includes code snippets for client-side implementation (React + Axios) and backend implementation (Node.js + Express).
This approach grants three key features such as asymmetric encryption, request freshness, and method & URL validation.
The method is applicable to all API interactions and prevents criminals from misusing APIs outside of the browser.
The project 'Winzy Social' implemented this approach to enhance the security of API interactions and prevent unauthorized or stale requests.
The author encourages readers to try this approach and enhance their application security with encrypted, timestamped CSRF tokens.
The code repository and Live Demo are available on GitHub in the article.

Private LLMs for GitHub Actions

GitHub has introduced SecondBrain, a new action that allows the use of LLMs (Language Model Models) within GitHub Actions workflows.
SecondBrain works by deploying Ollama as a Docker container to host LLMs and automates the process of constructing RAG (Retrieval Augmented Generation) prompts using git commit details.
The SecondBrain action enables users to generate summaries of commits to the main branch, making it easier to understand changes without inspecting the diff directly.
This action leverages a local, private LLM hosted by Ollama and does not require external services.
