Digigtal signature implementation, RSA, ElGamal, ECDSA
Compiled libsecp256k1 for using ECDSA signatures and secret/public key cryptography in your python projects.
ERC721 token that allows the users to mint using an authorization signed by the contract authorizer.
This project provides a small abstraction over the original WebCryptoAPI for ECDSA signatures
A basic application of Public Key Cryptography (using Elliptic Curve Digital Signatures) to sign and validate transactions
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.
In this study, we will look at the DeserializeSignature vulnerability, discovered in 2023, which allows attackers to create invalid signatures that can be accepted as valid by the Bitcoin network.
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
An ECDSA QR code id generator and verifier
— WIP: ecsda-node-202402.netlify.app/ — 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
Cryptographic utilities used by libp2p. Supported key types: ecdsa, ed25519, secp256k1 and rsa
A python implementation of ERC5564 for Stealth Addresses on Ethereuem as described https://eips.ethereum.org/EIPS/eip-5564
🔒 Pure Go GOST Digital Signer/TLS/VKO
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!).
