In today's world, cryptography plays a crucial role in people's daily lives. Much of the mathematics behind modern day cryptography comes from number theory. The Cryptography Treasure Hunt - an introduction to number theory based cryptography is a series of hands-on events in which participants decrypt a series of encrypted clues that ultimately lead to a prize.

By taking part in an edition of the Cryptography Treasure Hunt - an introduction to number theory based cryptography, contestants learn about encryption methods, from classical ciphers to modern cryptosystems, and the mathematics behind them.
