Brain Teasers, Riddles and Puzzles
Puzzles by Eric C. Harshbarger For my whole life I have been interested in puzzles and games, and in the last few years I have been fortunate enough to turn that passion into a profession. I design all types of puzzles: paper-and-pencil brainteasers, physical/manipulative puzzles, number puzzles, riddles, and all-day scavenger hunts for people to explore. My work has been for companies all around the world. Puzzles of mine have appeared in the Perplexcity alternate-reality games (by Mind Candy), in Wired magazine, GAMES magazine, at Lone Shark Games events, in puzzle calendars, on-line treasure hunts, and so forth. I host annual puzzle parties where many of my initial puzzle ideas are play-tested by very patient friends. Ever so slowly I will detail some of my creations on this page.

Recent developments in cryptography have added additional uses, including mechanisms for authenticating users on a network, ensuring the integrity of transmitted information and preventing users from repudiating (i.e. rejecting ownership of) their transmitted messages. In today's world of electronic commerce on the Internet, the need for secure communications is obviously crucial. Cryptographic technologies provide enterprises with the best mechanisms of protecting their information, without putting the business at risk by exposing it on the Net. What is Encryption?
