What is Hashing?
Hashing — Turning data into a fixed-size fingerprint that can't be turned back into the original. The same input always gives the same hash, so a site stores only the hash of each password and checks a login by hashing what was typed.
In a sentence
- “Thanks to hashing, our database holds password fingerprints, never the passwords.”
