C SSL

Open-source C projects categorized as SSL
Edit details

An SSL is security technology. It's a protocol for servers and web browsers that makes sure that data passed between the two are private. It was first developed by Netscape in 1995 for the purpose of ensuring privacy, authentication, and data integrity in Internet communications. SSL is the predecessor to the modern TLS encryption used today.

Top 19 C SSL Projects

  • OpenSSL

    TLS/SSL and crypto library

    • Project mention: Heartbleed and XZ Backdoor Learnings: Open Source Infrastructure Can Be Improved Efficiently With Moderate Funding | dev.to | 2024-04-07

    Today, April 7th, 2024, marks the 10-year anniversary since CVE-2014-0160 was published. This security vulnerability known as "Heartbleed" was a flaw in the OpenSSL cryptography software, the most popular option to implement Transport Layer Security (TLS). In more layman's terms, if you type https:// in your browser address bar, chances are high that you are interacting with OpenSSL.

  • ecapture

    Capture SSL/TLS text content without a CA certificate using eBPF. This tool is compatible with Linux/Android x86_64/aarch64.

  • 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.

  • ttyd

    Share your terminal over the web

    • Project mention: Any fun/interesting custom scripts or services being ran on your setup? | /r/homelab | 2023-05-16

    I do everything through a web browser -- I run an Arch VM with a modified version of ttyd running as a systemd service.

  • mbedTLS

    An open source, portable, easy to use, readable and flexible TLS library, and reference implementation of the PSA Cryptography API. Releases are on a varying cadence, typically around 3 - 6 months between releases.

    • Project mention: OpenWrt 23.05 | news.ycombinator.com | 2023-10-13

    It's work in progress: https://github.com/Mbed-TLS/mbedtls/blob/development/docs/ar...

    Newer version have okay-ish support, I'd guess the next OpenWRT release will have it again.
