A Rust end-to-end encryption library (e2eel) for key management using a Directed Acyclic Graph (DAG) of encrypted keys

A package that handles key pair generation and encryption / decryption of secrets using keys

CryptoLyzer is a fast, flexible, and comprehensive server cryptographic protocol (TLS, SSL, SSH, DNSSEC) and related setting (HTTP headers, DNS records) analyzer and fingerprint (JA3, HASSH tag) generator with Python API and CLI.

A sponge-based secure hash function that uses AES-256 as its internal PRF.

Cryptographic protocol and security-related protocol piece parser.

Free repository of cryptography-related data.

BitResurrector v3.0.3: Free software designed to search for abandoned Bitcoin assets by generating private keys and instantly checking balances. Implements 9-echelon entropy filtration, AVX-512 vectorization, and CUDA/OpenCL acceleration for massive secp256k1 key-space scanning. High efficiency is ensured by a Bloom filter, which real-time matches generated addresses against a global database containing all addresses with a positive balance existing in the blockchain.

QUIC-native TLS 1.3 implementation in Zig. RFC 8446/9001 compliant with zero external dependencies.

Explains why flash loans feel unprofitable to most users and how access barriers shape outcomes.

A powerful utility to hunt down Bitcoin private keys from deleted wallet.dat files or damaged hard drives. If you accidentally deleted your Bitcoin Core wallet or formatted your disk, this tool can help. It bypasses the file system and scans the raw data directly, looking for the unique "fingerprint" (ASN.1 signature) of Bitcoin private keys to recover them from the digital wreckage.

This script connects to a locally running full node core wallet, scans a specified range of blocks,and extracts public keys found in transactions into an archive.Used for public key research projects such as RCKangaroo,keyhunt,BitCrack,bsgsd,keyhuntcuda,etc. for BTC,ETH,BCH,LTC,DOGE,DASH,ZEC,etc.

Zig Hardware Security Module library for PIV, CAC, and YubiKey tokens via PC/SC. Supports certificates, PIN management, signing, and decryption.

Proof of Concept: transfer telegram messages from a relay server (actual go version) to a old Palm Pixi WebOS armv6 mobile phone (go version 1.11) with asymetric key pair.

scared is a side-channel analysis framework.

estraces is a Python library to manipulate side-channel trace sets. It aims at giving a clear and uniform API to handle traces samples and metadata for various persistency and file formats.

A minimalist implementation of AES algorithms in C

Bitcoin Mini Key Hunter is a tool that focuses on searching for 22-digit private keys starting with S and performing cracking drills. It uses the powerful GPU parallel computing capabilities of CUDA technology, similar to research tools such as brainflayer,keyhunt,BitCrack, ecloop,keyhunt cuda,etc.

KeyKiller is the world's highest-performing CPU-based Satoshi password cracker. It leverages modern CPU instruction sets like AVX2 and AVX512 to achieve unparalleled computing performance. Deeply optimized for the operating system, it strikes a balance between speed and accuracy, making it the ultimate tool for password cracking.
