DigitalCertiAnalytics is an advanced tool for analysing and visualising digital certificates. It allows you to explore various aspects of certificates, such as validity, signing algorithms and security policies, presenting the results in intuitive graphs.

To develop a cryptography simulation that demonstrates secure communication over UDP using OpenSSL/MbedTLS libraries which showcases the use of cryptographic protocols for encryption, confidentiality.

This repository contains an example Node.js application showcasing the implementation of a middleware for encrypting and decrypting HTTPS request payloads in JSON format. The middleware uses the Advanced Encryption Standard (AES) with the Cipher Block Chaining (CBC) mode for encryption and decryption.

Interactively learn how digital certificates are issued: keys → CSR → CA review → certificate, entirely in-browser.
