Microsoft Threat Intelligence identified a large-scale npm supply chain attack affecting 32 maliciously modified packages across more than 90 versions under the @redhat-cloud-services npm scope. The ...

Last time, we used Python to create a Caesar cipher. It simply shifts characters by a fixed number. and other fundamentals of cryptographic technology were packed into it. However, the Caesar cipher ...

Key recovery attack on SPN ciphers such as AES is NP hard in complexity. Previous studies have estimated the quantum resources required for implementing Grover’s key search for AES, but these are ...

March 9 to March 19, 2026. Ten days. Seven categories. Sixty challenges. One team representing Uganda on the global and African stage. This is not a summary. This is an honest account of what ...

A comprehensive educational cipher toolbox for encryption and decryption, featuring both classical and modern cryptographic algorithms — now with a built-in MCP (Model Context Protocol) server for AI ...

This paper proposes an innovative method to enhance the security of color images by integrating hybrid cryptographic techniques, specifically using Sine maps and a double application of the logistic ...

This repository contains my complete solutions to the legendary Karan's Mega Project List — a curated collection of programming challenges designed to improve coding skills across multiple domains.

As the title implies, these algorithms are just for fun (an excuse to hone your Python skills, if you need one). Please don't use them to encrypt any sensitive data. You've been warned. The first and ...

There is educational television, and there is “educational” television. This list deals almost exclusively with the latter. There are facts to be found in these historical TV series, or at least ...
