C Authentication

Open-source C projects categorized as Authentication Edit details

Top 6 C Authentication Projects

  • FreeRADIUS

    FreeRADIUS - A multi-protocol policy server.

    Project mention: Radius solution that can easily integrate with LDAP (for wifi) | reddit.com/r/networking | 2022-05-19

    I wonder why your sys admins didn't try FreeRADIUS. It ships with detailed config examples also for using LDAP for authentication.

  • Themis

    Easy to use cryptographic framework for data protection: secure messaging with forward secrecy and secure data storage. Has unified APIs across 14 platforms.

    Project mention: Themis: Strong, usable cryptography for busy people | news.ycombinator.com | 2022-02-17
  • Scout APM

    Truly a developer’s best friend. Scout APM is great for developers who want to find and fix performance issues in their applications. With Scout, we'll take care of the bugs so you can focus on building great things 🚀.

  • OpenID

    OpenID Certified™ OpenID Connect Relying Party implementation for Apache HTTP Server 2.x

    Project mention: Keycloak: Open-Source Identity and Access Management | news.ycombinator.com | 2022-05-04

    I really like https://tools.ietf.org/html/draft-ietf-oauth-security-topics with it's evergreen approach and looking forward to oauth2.1 to sum up the current best practices.

    Depending on your use case I have good experience with https://github.com/zmartzone/mod_auth_openidc and https://github.com/panva/node-oidc-provider.

    https://github.com/OpenIDC/pyoidc also might be a good choice as security researchers in that area did take a look in it...

  • pam_reattach

    Reattach to the user's GUI session on macOS during authentication (for Touch ID support in tmux)

  • eid-mw

    eID Middleware (main repository)

    Project mention: Reading id card | reddit.com/r/learnpython | 2021-11-10

    I'm not sure if that's even possible, the system works through proprietary middleware, and that would require you to implement their SDK. See https://github.com/Fedict/eid-mw/tree/master/doc/sdk/documentation

  • ecc

    elliptic-curve cryptography

    Project mention: blst VS ecc - a user suggested alternative | libhunt.com/r/blst | 2022-01-26

    wraps the library in a more C like api and provides bindings to other platforms
