This project provides a small abstraction over the original WebCryptoAPI for ECDSA signatures
Basics of elliptic curves, EC over finite fields and ECDSA.
Secret independent (constant time) implementation of deterministic ECDSA nonces (RFC 6979).
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.
[WIP] Bitcoin-like Cryptocurrency written in Python
ECDSA Julia implementation (toy version, not resistant to timing attacks)
A basic application of Public Key Cryptography (using Elliptic Curve Digital Signatures) to sign and validate transactions
Minimalistic Secp256r1 ECDSA/ECDH Tool written in Go
Code 91101 is a mysterious message from the depths of the digital world
This is a basic application of Public Key Cryptography.
A provably fair Verifiable Random Function (VRF) that provides cryptographic outputs to confirm games were fair
ECDSA Keygen is a Python-based tool for generating and managing ECDSA cryptographic keys. It offers a secure, efficient solution for developers and security professionals to handle digital signatures and verification in cybersecurity tasks.
In this project you'll have a simple react front-end which will communicate with a single server. This server will be responsible for transferring balances between accounts. Since it's a single server, it is centralized, so we'll need to trust that the server operator is not malicious for this exercise (more on this later!).
A sample ecdsa node project incorporating public key cryptography so transfers can only be completed with a valid signature
Python Blockchain
a small encryption tool, for end-user management of encryption/siging keys
Implemented Public Key Cryptography to transact funds between accounts.
WIP -- notes: Incorporate Public Key Cryptography so transfers can only be completed with a valid signature. The person sending the transaction should have to verify that they own the private key corresponding to the address that is sending funds
a command line anonymous identity manager
