 [[Category:Mathematical operations]]Tasks in this category have to do with encrypting data using various algorithms.
-Note that encryption is not the same as a [[Category:Checksums|checksum]]. With encryption, the derived data carries and encrypted form of the original data, and can be manipulated to recreate the original input. A checksum is simply a sequence of characters (usually just a few characters in length) that cannot be converted back to the original form (because more than input can have the same checksum).

A checksum is simply a sequence of characters (usually just a few characters in length) that cannot be converted back to the original form (because more than one input can have the same checksum).
