ring is focused on the implementation, testing, and optimization of a core set of cryptographic operations exposed via an easy-to-use (and hard-to-misuse) API. ring exposes a Rust API and is written in a hybrid of Rust, C, and assembly language. ring is focused on general-purpose cryptography. WebPKI X.509 certificate validation is done in the webpki project, which is built on top of ring. Also, multiple groups are working on implementations of cryptographic protocols like TLS, SSH, and DNSSEC on top of ring.

An AX.25 packet radio chat protocol with support for digital signatures and binary compression. Like IRC over radio waves 📡. Chattervox implements a minimal packet radio protocol on top of AX.25 that can be used with a terminal node controller (TNC) like Direwolf to transmit and receive digitally signed messages using audio frequency shift keying modulation (AFSK). In the United States, it's illegal to broadcast encrypted messages on amateur radio frequencies. Chattervox respects this law, while using elliptic curve cryptography and digital signatures to protect against message spoofing.

To get started, first define your key encoder and raw private/public keys.As shown above, there is built in support for SECP256k1 (the curve Bitcoin uses), but you can pass in your own curve parameters for any curve you'd like.

A key system based around accounts that each have hierarchical deterministic (HD) keychains with ECDSA keypairs (the ones Bitcoin uses).A master private keychain is the highest level abstraction of keys. It represents the root or master private key for the application and/or device. Account-specific private keychains can be derived from it, which can then be used to derive account-specific public keychains.

A compilation-free, always up-to-date encryption library for Python that works on Windows, OS X, Linux and BSD. Supports the following versions of Python: 2.6, 2.7, 3.2, 3.3, 3.4, 3.5, 3.6 and pypy. OS X 10.6 will not be supported due to a lack of available cryptographic primitives and due to lack of vendor support.

Let's recover the private-key for two signatures sharing the same nonce k. Note how chosing the same nonce k results in both signatures having an identical signature value r. To find good candidates for an ECDSA nonce reuse check for signatures sharing the same r, pubkey on curve for different messages (or hashes). E.g. blockchain projects based off bitcoind are usually good sources of ECDSA signature material. The library is written in a way that it tries to upgrade pubkey only ecdsa objects to private key enabled ecdsa objects upon successful recovery. This makes it easy to work with recovered key objects. The library performs both ECDSA and DSA key recovery.

This is a work trying to reproduce and improve on Billy Bob Brumley and Nicola Tuveri - Remote Timing Attacks are Still Practical. It works on an unpatched version of OpenSSL, but theorically it should work on any TLS framework that has such a timing attack (and not only on binary curves).

This gem implements the Elliptic Curve Digital Signature Algorithm (ECDSA) almost entirely in pure Ruby. It aims to be easier to use and easier to understand than Ruby's OpenSSL EC support. This gem does use OpenSSL but it only uses it to decode and encode ASN1 strings for ECDSA signatures. All cryptographic calculations are done in pure Ruby. The main classes of this gem are ECDSA::Group, ECDSA::Point, and ECDSA::Signature. These classes operate on Ruby integers and do not deal at all with binary formatting. Encoding and decoding of binary formats is solely handled by classes under the ECDSA::Format module.
ecdsa cryptographysignatory - Multi-provider digital signature library for Rust
A pure Rust multi-provider digital signature library with support for elliptic curve digital signature algorithms, namely ECDSA (described in FIPS 186-4) and Ed25519 (described in RFC 8032). Signatory provides a thread-safe and object-safe API and implements providers for many popular Rust crates, including ed25519-dalek, secp256k1-rs, ring, and sodiumoxide.

This module provides the functionality necessary to use Let's Encrypt API and generate free SSL certificates for your domains. It can also be used to generate private RSA (and from version 0.20 also ECC) keys or Certificate Signing Requests without resorting to openssl command line. Crypt::LE is shipped with a self-sufficient client for obtaining SSL certificates - le.pl. Both ACME v1 and ACME v2 protocols and wildcard certificate issuance are supported.

Here we use the terminology that is a bit different from the terminology in other HD key systems, like in the original BIP32 proposal. We take "keychain" to mean a hierarchical deterministic BIP32 key, where any number of keys can be derived from it.
