python-ecdsa - pure-python ECDSA signature/verification

This is an easy-to-use implementation of ECDSA cryptography (Elliptic Curve Digital Signature Algorithm), implemented purely in Python, released under the MIT license. With this library, you can quickly create keypairs (signing key and verifying key), sign messages, and verify the signatures. The keys and signatures are very short, making them easy to handle and incorporate into other protocols. This library provides key generation, signing, and verifying, for five popular NIST "Suite B" GF(p) curves, with key lengths of 192, 224, 256, 384, and 521 bits. The "short names" for these curves, as known by the OpenSSL tool (openssl ecparam -list_curves), are: prime192v1, secp224r1, prime256v1, secp384r1, and secp521r1. It also includes the 256-bit curve used by Bitcoin, whose short name is secp256k1. No other curves are included, but it would not be too hard to add more.

Litecoin - Global Decentralized Currency

Litecoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Litecoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Litecoin Core is the name of open source software which enables the use of this currency.

Minisign is a dead simple tool to sign files and verify signatures. Minisign uses the EdDSA signature system, and deterministic signature schemes are fragile against fault attacks. However, conducting these requires physical access or the attacker having access to the same physical host.

awesome-coins - ₿ A guide (for humans!) to cryto-currencies and their algos.

A cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency. There are many algorithms used in many different crypto–currencies. This document serves to provide a simple map to reference which are for what, as well as provide a nice list of helpful services and utilities for managing coins.

Bitcoin - Most popular Crypto Currency

Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

Charm-crypto - A Python-based rapid prototyping framework for cryptosystems

Charm is a framework for rapidly prototyping advanced cryptosystems. Based on the Python language, it was designed from the ground up to minimize development time and code complexity while promoting the reuse of components. It supports Base crypto library, including symmetric encryption schemes, hash functions, PRNGs, digital signature, encryption and lot more.

bitauth - Authenticate with web services utilizing the same strategy as Bitcoin.

BitAuth is a way to do secure, passwordless authentication using the cryptography in Bitcoin. Instead of using a shared secret, the client signs each request using a private key and the server checks to make sure the signature is valid and matches the public key.BitAuth uses the same technology in Bitcoin. A public private key pair is created using elliptic curve secp256k1. The public SIN (System identification number), like a bitcoin address, is the RIPEMD 160, SHA256 hash of the public key. See for complete details.

Botan - Crypto library for C++

Botan (Japanese for peony) is a cryptography library written in C++11. Botan's goal is to be the best option for cryptography in new C++ code by offering the tools necessary to implement a range of practical systems, such as TLS/DTLS, PKIX certificate handling, PKCS#11 and TPM hardware support, password hashing, and post quantum crypto schemes. In addition to the C++, botan has a C89 API specifically designed to be easy to call from other languages. A Python binding using ctypes is included, and several other language bindings are available.

The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes.

Zcash - Internet Money

Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Bitcoin and most cryptocurrencies expose your entire payment history to the public. Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.
