cryptography

Free repository of cryptography-related data.

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

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 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.

⚡ Essential JavaScript libraries/utilities for Node.js and the web

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.

scared is a side-channel analysis framework.

A no_std-compatible library for ergonomic byte array operations with optional security hardening. Supports multiple input formats (hex, binary, UTF-8), bitwise operations, and comprehensive type conversions with minimal dependencies.

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.

D(HE)ater is a proof of concept implementation of the D(HE)at attack (CVE-2002-20001) through which denial-of-service can be performed by enforcing the Diffie-Hellman key exchange.

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

CLI tool for compressing and XOR encoding file.

After optimization, version 3080 is equivalent to version 4090. I fixed address matching errors and private key conversion errors, modified the random generator, added puzzles suitable for specific regions, and more. It is commonly used in puzzle games, Brainflayer, Keyhunt, BitCrack, VanitySearch, etc.

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.

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.

This C language tool converts Bitcoin private key or public key or public key hash 160, calculates various addresses, including P2PKH, P2SH, SegWit and other formats, and supports conversion between hexadecimal and WIF formats of private keys.

Cryptographic protocol and security-related protocol piece parser.

JetstreamDB is a universal filesystem, cache, memory, database. It is a component to build into solutions for management consulting customers. It has been running in production since April 2023. The logo was inspired by the tea clipper. It intends to be a great data store without AI like tea clippers took the seas before ironclads.

It is an open-source component, but we offer paid services with audit, system security reviews, benchmarking, and warranty. Jetstreamdb is available up to 6 TB low latency RAM with optional extra 50 TB SSD configurations for about $150/hr. https://calendly.com/hq-schmied/30min
