Open Source Python Cryptography Software for Linux

The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. wolfSSL relies on the FIPS 140-2 validated wolfCrypt library for all cryptographic functionality.

An open source implementation of the FIDO2 protocol to support passwordless strong authentication using public-key cryptography. Supports registration, authentication (all platforms), and transaction authorization (for native Android apps).

OpenSEED is open source implementation for SEED, the 128-bit Symmetric Block Cipher which is used widely among Korean Financial & Banking Companies. OpenSEED will implement TLS over SEED, also.

The Secure Remote Log Monitor (SRLM) project provides client and server utilities that collect application or system log files from multiple systems over an untrusted network onto a central server for analysis and action.

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.
