A collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library.

A powerful security toolkit which allows even inexperienced crypto programmers to easily add encryption and authentication services to their software.

Implements an interface to access block and stream encryption algorithms. Includes a full list of algorithms supported. ANSI C.

The code from the Applied Cryptography disk, available outside the US.

Implementation of RC5 (128) in C.

A free implementation of the public key cryptography system with source code and documentation.

Implements the public key signature system QuartzLight in Java where QuartzLight refers to a research version of the Quartz standard.

Allows hash, checksum and HMAC calculations to be added to Windows applications. C++, commercial.

An open-source C++ crypto library that includes block and stream ciphers, hash functions, MACs, and public key algorithms, along with an easy to use filter-based interface.

Collection of programming examples on encryption including: file encryption, steganography in images and sound, data base record encryption, and password verification. All written in Pascal, all source code available.

Offers SSL interception module to decode and modify SSL traffic on Windows OS.

Free library of cryptographic schemes: includes ciphers, message authentication codes, one-way hash functions, public-key cryptosystems, and key agreement schemes.
