Data security project aims to implement various algorithms using c#

Simple program to encrypt and decrypt files using asymetric methods.

Shows in a simple way how the sender and receiver function of Alice and Bob works in encrypted form. The ECDiffieHellman (ec key exchange) and ECDSA (ec digital signing) algorithms are used here. The elliptic curves are always selected randomly so that everything in the temporary area is used. Was slightly adapted in 2024 and updated to DotNet8.

A compact API and implementation of abelian group algebra commonly used in asymmetric cryptography, fully written in C#.

A Windows desktop app for cryptographically protecting files.

Hash and AES Cryptography in .Net Core

👑 🏆 💰 This code provides the basic steps required to locally verify an ID Token signed using asymmetric encryption (eg. RS256). It uses packages from Microsoft for key parsing and token validation. The code is also testable and comes with a suite of unit tests.

Net Core Jwt Asymmetric Signing with public private key

C# console app for rsa encryption on texts larger than the encrypting key size and storing to file for later decryption

Encrypted File System simulator.
