Cryptography is the art of creating mathematical assurances for who can do what with data, including but not limited the classical example of encrypting messages so that only the key-holder can read it. Cryptography lives at an intersection of math, programming, and computer science.
This subreddit covers the theory and practice of modern and strong cryptography, and it is a technical subreddit focused on the algorithms and implementations of cryptography.
Dedicated towards the branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime. The field is the application of several information security principles and aims to provide for attribution and event reconstruction following forth from audit processes. This subreddit is not limited to just the computers and encompasses all media that may also fall under digital forensics (e.g., cellphones, video, etc.).
