Who should attend: System, network, and security administrators; people who communicate remotely and require security; developers of applications which require authentication or privacy; managers who need to better understand what is and is not possible.

While cryptography is becoming increasingly important, and cryptographic algorithms are well understood, the problem is that actually using cryptography (either embedded in day-to-day applications or developing new "crypto-enabled" applications) is hard.

In this tutorial, you will gain an understanding of the capabilities of cryptographic techniques, some of the common pitfalls in their use, and some of the techniques for successfully using cryptography in applications. After completing this tutorial, participants will know many of the tricks of successfully using cryptography in their work or applications.

Topics will include:

	Historical perspective
	Brief introduction to cryptographic primitives    Random numbers    Hash functions and message authentication codes    Block and stream ciphers (symmetric ciphers)    Public key encryption and digital signatures
	Useful tools    PGP old and new (versions 2.6.x and 5.0)    SSH (Secure Shell), for when you are on the road    Tripwire, helping to detect break-ins    CFS, the Cryptographic File System for UNIX
	Cryptographic toolkits    SSLeay (public SSL implementation library)    Cryptlib (public general purpose encryption library)
	Export regulations (an apolitical assessment)    how to comply to avoid nasty things    various recovery strategies
