sigtool - Ed25519 signing & verification for arbitary files; like OpenBSD signifiy but written in Golang - only easier and simpler

  •        21

sigtool is an opinionated tool to generate, sign and verify Ed25519 signatures on files. In many ways, it is like like OpenBSD's signify_ -- except written in Golang and definitely easier to use. It can sign and verify very large files - it prehashes the files with SHA-512 and then signs the SHA-512 checksum.

python-ecdsa - pure-python ECDSA signature/verification

  •    Python

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.

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

  •    Javascript

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 https://en.bitcoin.it/wiki/Identity_protocol_v1 for complete details.

jSignature - jQuery plugin for adding web signature functionality

  •    Javascript

jSignature is a jQuery plugin which simplifies creation of a signature capture field in the browser window, allowing a user to draw a signature using mouse, pen, or finger. jSignature captures signature as vector outlines of the strokes. Although jSignature can export great bitmap (PNG) too, extraction of highly scalable stroke movement coordinates (aka vector image) of the signature allows much greater flexibility of signature rendering.
