Abstract: Techniques of breaking encryptions are becoming increasingly advanced as encryption methods also change. Cryptanalysis normally depends on algorithmic, statistical or brute force attacks ...

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 is a very simple (and NOT a highly optimized and secure) implementation of AES only written to teach you the BASICS of this algorithm. I used a tutorial previously available on progressive-coding ...

Before we move into the meat of this article, let’s define a couple terms related to cryptography. The syllable crypt may make you think of tombs, but it comes from a Greek word that means “hidden” or ...

There are a variety of innovations that contributed to blockchain technology, one of the most important is hashing. But what is hashing in blockchain? Without it blockchains would be insecure, and ...

Abstract: With the internet having reached a level that merges with our lives, growing explosively during the last several decades, data security has become a main concern for anyone connected to the ...

Public key cryptography seems magical to everyone, even those who understand it. In this post, I’m going to explain public key cryptography. Public Key Cryptography is based on asymmetric cryptography ...

Substituting letter pairs (bigrams) is an encryption method that was already known in the 16th century. Is it still secure today? To develop an encryption method that only requires pen and paper is a ...
