Top 23 Ecdsa Open-Source Projects

  • PHPSecLib

    PHP Secure Communications Library

    • Project mention: How to install software on VPS through PHP? | /r/PHP | 2023-10-24

    I recommend using PHPSecLib which has a powerful SSH library that is far more versatile than the official PHP SSH extension.

  • swift-crypto

    Open-source implementation of a substantial portion of the API of Apple CryptoKit suitable for use on Linux platforms.

    • Project mention: Swift for Android: How to use Swift-Crypto with Android Studio | dev.to | 2023-11-14

    dependencies: [ .package(url: "https://github.com/scade-platform/swift-java.git", branch: "main"), .package(url: "https://github.com/apple/swift-crypto.git", .branch("main")) ]

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • multi-party-ecdsa

    Rust implementation of {t,n}-threshold ECDSA (elliptic curve digital signature algorithm).

  • python-ecdsa

    pure-python ECDSA signature/verification and ECDH key agreement

  • docker-nginx-certbot

    Automatically create and renew website certificates for free using the Let's Encrypt certificate authority.

  • noble-secp256k1

    Fastest 4KB JS implementation of secp256k1 signatures and ECDH

    • Project mention: A beginner's guide to constant-time cryptography (2017) | news.ycombinator.com | 2024-02-22

    I noticed in July of 2022 that Go did exactly the vulnerable example and reported it to the security team.

    https://github.com/golang/go/issues/53849

    It was fixed as of Go 1.21 https://go.dev/doc/go1.21

    ---

    The article cites JavaScript, which is not constant time. There's no sure way to do constant time operations in JavaScript and thus no secure way to do crypto directly in Javascript. Browsers like Firefox depend on low level calls which should be implemented in languages that are constant time capable.

    JavaScript needs something like constant time WASM in order to do crypto securely, but seeing the only constant time WASM project on GitHub has only 16 stars and the last commit was 2 years ago, it doesn't appear to have much interest. https://github.com/WebAssembly/constant-time

    However, for JavaScript, I recommend Paul's library Noble which is "hardened to be algorithmically constant time". It is by far the best library available for JavaScript. https://github.com/paulmillr/noble-secp256k1

  • RustCrypto Elliptic Curves

    Collection of pure Rust elliptic curve implementations: NIST P-224, P-256, P-384, P-521, secp256k1, SM2

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • noble-curves

    Audited & minimal JS implementation of elliptic curve cryptography.

    • Project mention: The AT protocol is the most obtuse crock of s* | news.ycombinator.com | 2023-05-09

    BlueSky uses @noble/secp256k1 which performs this stuff in Javascript, with about 880* verifications per second on the Apple M2 (a chip with a relatively high IPC, likely higher than your average server).

    Verifying those messages will take about a minute of CPU time per user (assuming no impact from cache misses due to threads swapping in and out and processing new data). I think that's quite significant.

  • putty-cac

    Windows Secure Shell Client With Support For Smart Cards, Certificates, & FIDO Keys

    • Project mention: NIST: Personal Identity Verification (PIV) of Federal Employees and Contractors | news.ycombinator.com | 2024-03-23

    PuTTY-CAC was an interesting, although imperfect solution to using PIV/CAC cards together with SSH. I remember piloting it from 2013-2014 at an agency. Back then, it was maintained by Dan Risacher[0]. Nowadays it is maintained on GitHub[1] and adopted some interesting features like FIDO.

  • signatures

    Cryptographic signature algorithms: DSA, ECDSA, Ed25519

  • GpgFrontend

    A free, open-source, robust yet user-friendly, compact and cross-platform tool for OpenPGP encryption. It stands out as an exceptional GUI frontend for the modern GnuPG (gpg).

    • Project mention: GpgFrontend: Open-source, Cross-platform GnuPG Front end | news.ycombinator.com | 2024-03-16

  • ecdsa-private-key-recovery

    A simple library to recover the private key of ECDSA and DSA signatures sharing the same nonce k and therefore having identical signature parameter r

    • Project mention: If I sign multiple messages with the same nonce, my private key can be extracted? | /r/ethdev | 2023-06-27

  • Crypt-LE

    Crypt::LE - Let's Encrypt / Buypass / ZeroSSL and other ACME-servers client and library in Perl for obtaining free SSL certificates (inc. generating RSA/ECC keys and CSRs). HTTP/DNS verification is supported out of the box, EAB (External Account Binding) supported, easily extended with plugins, easily dockerized.

  • cryptotools

  • zkp-ecdsa

    Proves knowledge of an ECDSA-P256 signature under one of many public keys that are stored in a list.

  • bip32

    A BIP32 compatible library.

  • VbAsyncSocket

    Sockets with pure VB6 impl of TLS encryption

    • Project mention: Modern TLS/SSL on 16-bit Windows | news.ycombinator.com | 2023-06-26

    I wonder if it is possible to make https://github.com/wqweto/VbAsyncSocket compile on Visual Basic 4, then you could target 16 bit.

  • btclib

    btclib: a python3 library for 'bitcoin cryptography'

  • bitcoin-recover-privkey

    Proof of concept of bitcoin private key recovery using weak ECDSA signatures
