Substitution ciphers, military encryption devices, hashing, symmetric key algorithms - how well do you know them?
The complexity of encryption schemes has been increased dramatically in an attempt to outpace the development of computational tools designed to crack them. Now it's important to devise algorithms that can't be brute forced for trillions of years in the hopes that they will remain secure long enough to be useful before they, too, are broken. Here's a quiz about encryption to see how well you are versed in one of security's most important components. Keep track of your score and check at the end to see how well you stack up.
