A type of monoalphabetic substitution cipher, wherein each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple function `(ax + b) mod m`.

the deliberate act of creating obfuscated code by making source or machine code difficult to understand from a human point of view.

a property that, if proven to be possesed, makes an algorithm "immune" to time-memory tradeoffs, by "punishing" memory reductions. Usually algorithms possesing this property can't e…
