An Illustrated Guide to Cryptographic Hashes

A "hash" (also called a "digest", and informally a "checksum") is a kind of "signature" for a stream of data that represents the contents. The closest real-life analog we can think is "a tamper-evident seal on a software package": if you open the box (change the file), it's detected.

The illustrated guide covers the following topics: (Very interesting read)
- How are hashes used?
- Verifying file integrity
- Hashing passwords
- Digitally Signed Documents
- Hash Collisions?
- What's inside a cryptographic hash?
