Cryptography for Programmers

For centuries people have used crypto to build (and break) secure systems. Computers have only raised the pitch of conflict, providing enormous cryptographic power at commodity prices. Most programmers do not write their own crypto libraries, instead relying on the services of an operating system or virtual machine. But even with all this support, building secure systems is a daunting task.

This talk will cover three things all programmers
need to know:

1. the basic tools of computer crypto
2. the programmatic APIs to these tools
3. common programming mistakes that can undermine otherwise secure systems
   You will learn the basics of hashing, message digests, public key encryption, symmetric key encryption, certificates, and key management. With each,
   you will see programmatic examples, with advice for correct usage.
