Crypto Deep Tools a set of scripts for detailed cryptanalysis of the Blockchain network in cryptocurrency Bitcoin

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.

All about digital signature

A solidity library to verify a secp256r1 signature in several ways

A provably fair Verifiable Random Function (VRF) that provides cryptographic outputs to confirm games were fair

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.
