Projects

OpenSSL

The OpenSSL Project is 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. The project ... [More] is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and dev [Less]

GnuTLS

GnuTLS is a secure communications library implementing the SSL and TLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols as well as APIs to parse and write X.509, PKCS #12, OpenPGP and other ... [More] required structures. It is aimed to be portable and efficient with focus on security and interoperability. [Less]

Bouncy Castle

Here at the Bouncy Castle, we believe in encryption. That's something that's near and dear to our hearts. We believe so strongly in encryption, that we've gone to the effort to provide some for everybody.

strongSwan

strongSwan is an open source IPsec-based VPN solution. It features IKEv1 and IKEv2 keying capabilities and runs on Linux 2.6 and 3.x kernels, Android, Maemo, FreeBSD, and Mac OS X.

OpenSC

OpenSC provides a set of libraries and utilities to access smart cards. Its main focus is on cards that support cryptographic operations, and facilitate their use in security applications such as mail encryption, authentication, and digital signature. OpenSC implements the PKCS#11 API so ... [More] applications supporting this API such as Mozilla Firefox and Thunderbird can use it. OpenSC implements the PKCS#15 standard and aims to be compatible with every software that does so, too. [Less]

Openswan

Openswan is an Open Source implementation of IPsec for the Linux operating system. Is it a code fork of the FreeS/WAN project, started by a few of the developers who were growing frustrated with the politics surrounding the FreeS/WAN project.

pyOpenSSL

Python wrapper around a small subset of the OpenSSL library. Includes: X509 Certificates, SSL Context objects, SSL Connection objects using Python sockets as transport layer.

M2Crypto

M2Crypto is the most complete Python wrapper for OpenSSL featuring RSA, DSA, DH, HMACs, message digests, symmetric ciphers (including AES); SSL functionality to implement clients and servers; HTTPS extensions to Python's httplib, urllib, and xmlrpclib; unforgeable HMAC'ing AuthCookies for ... [More] web session management; FTP/TLS client and server; S/MIME; ZServerSSL: A HTTPS server for Zope and ZSmime: An S/MIME messenger for Zope. [Less]

CyaSSL

CyaSSL is an embedded SSL implementation (up to TLS 1.2 and DTLS) for software developers building security functionality into their applications and devices. It is optimized for resource-constrained environments and can be up to 20x smaller than OpenSSL. CyaSSL is ported to a long list of ... [More] environments, including Win/Linux/Mac, Solaris, ThreadX, VxWorks, FreeBSD, NetBSD, OpenBSD, embedded Linux, WinCE, Haiku, OpenWRT, iOS, Android, Nintendo Wii and Gamecube through DevKitPro, QNX, MontaVista, OpenCL, NonStop, TRON/ITRON/µITRON, µC/OS, FreeRTOS, MQX, and Nucleus. Supported chipsets include ARM, Intel, Motorola and others. CyaSSL cryptography includes assembly optimizations for several environments, including ARM, AVR 32, and Intel (with support for Intel AES-NI). [Less]

PHP Secure Communications Library

MIT-licensed pure-PHP implementations of an arbitrary-precision integer arithmetic library, fully PKCS#1 (v2.1) compliant RSA, DES, 3DES, RC4, Rijndael, AES, SSH-1, SSH-2, SFTP, and X.509.
