cryptlib is an open-source cross-platform software security toolkit library. It is distributed under the Sleepycat License,[2] a free software license compatible with the GNU General Public License.[3] Alternatively, cryptlib is available under a proprietary license for those preferring to use it under proprietary terms.[4]

Features

cryptlib is a security toolkit library that allows programmers to incorporate encryption and authentication services to software. It provides a high-level interface, so that strong security capabilities can be added to an application without needing to know many of the low-level details of encryption or authentication algorithms. Extensive documentation in the form of a 400+ page programming manual is available.[5]


cryptlib can make use of the cryptographic capabilities of a variety of external cryptographic devices such as hardware cryptographic accelerators, Fortezza cards, PKCS #11 devices, hardware security modules (HSMs), and cryptographic smart cards. It can be used with a variety of cryptography devices that have received FIPS 140 or ITSEC/Common Criteria certification. The cryptographic device interface also provides a general-purpose plug-in capability for adding new functionality that can be used by cryptlib.

cryptlib is written in C and supports BeOS, DOS, IBM MVS, Mac OS X, OS/2, Tandem, a variety of Unix versions (including AIX, Digital Unix, DGUX, FreeBSD/NetBSD/OpenBSD, HP-UX, IRIX, Linux, MP-RAS, OSF/1, QNX, SCO UnixWare, Solaris, SunOS, Ultrix, and UTS4), VM/CMS, Windows 3.x, Windows 95/98/ME, Windows CE/PocketPC/SmartPhone and Windows NT/2000/XP/Vista. It is designed to be portable to other embedded system environments. It is available as a standard DLL. Language bindings are available for C / C++, C# / .NET, Delphi,[6] Java, Python, and Visual Basic (VB).
