Bit::Vector is a (stand-alone) C library and an object-oriented Perl module (with overloaded operators) which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" (e.g. for cryptography), and boolean matrices (all of arbitrary size) very efficiently.

OpenSC provides a set of libraries and utilities to work with smart cards. Its main focus is on cards that support cryptographic operations, and facilitates their use in security applications such as authentication, mail encryption, and digital signatures. OpenSC implements the PKCS#11 API so that applications supporting this API (such as Mozilla Firefox and Thunderbird) can use it. On the card, OpenSC implements the PKCS#15 standard, and aims to be compatible with every software/card that does so.

Ubuntu Privacy Remix is a modified live CD based on Ubuntu Linux. UPR is not intended for permanent installation on a hard disk. The goal of Ubuntu Privacy Remix is to provide an isolated working environment where private data can be dealt with safely. The system installed on the computer running UPR remains untouched. It does this by removing support for network devices as well as local hard disks. Ubuntu Privacy Remix includes TrueCrypt and GnuPG for encryption and introduces "extended TrueCrypt volumes".

SoftHSM is an implementation of a cryptographic store accessible through a PKCS#11 interface. You can use it to explore PKCS#11 without having a Hardware Security Module. It is being developed as a part of the OpenDNSSEC project. SoftHSM uses Botan for its cryptographic operations.

The LibPKI Project is aimed to provide an easy-to-use PKI library for PKI-enabled application development. The library provides the developer with all the needed functionality to manage certificates, from generation to validation. It helps developers integrate X509 digital certificates into their applications, and implement complex cryptographic operations with a few simple function calls using a high-level cryptographic API. The library constitutes the core of other OpenCA Labs Projects like the PRQP Server, the OCSP Responder, and the OpenCA-NG PKI.

ipt_pkd is an iptables extension implementing port knock detection with SPA (single packet authorization). This project provides 3 parts: the kernel module ipt_pkd, the iptables user space module libipt_pkd.so, and a user space client knock program. For the knock packet, it uses a UDP packet sent to a random port that contains a SHA-256 of a timestamp, small header, random bytes, and a shared key. ipt_pkd checks the time window of the packet and does the SHA-256 to verify the packet. The shared key is never sent.

PolarSSL is a light-weight cryptographic and SSL/TLS library written in C. PolarSSL makes it easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) applications with as little hassle as possible. Loose coupling of the components inside the library means that it is easy to separate the parts that are needed, without needing to include the total library. PolarSSL is written with embedded systems in mind and has been ported on a number of architectures, including ARM, PowerPC, MIPS, and Motorola 68000. The source is written to have very loose coupling, enabling easy integration of parts in other software projects. Very loosely coupled cryptographic algorithms for MD2, MD4, MD5, SHA1, SHA-256, SHA-512, AES, Camellia, DES, Triple DES, ARC3, and RSA are included.

J2SSH is an object-orientated Java implementation of the SSH version 2 protocol. It provides a rich, powerful, and extensible SSH API that enables developers to gain access to SSH servers and to develop entire SSH client/server frameworks. The API library provides a fully-featured SSH2 implementation specifically designed for cross-platform development. Higher level components, representing both the standard SSH client and SSH servers, are provided which implement the protocol specification for user sessions and port forwarding. The specification currently supports public key and password authentication and a full implementation of the SFTP protocol.
