What is a hash for?
A hash function turns any data into a fixed-length fingerprint. It is used to check file integrity and detect changes. For storing passwords, use slow algorithms such as bcrypt or Argon2 rather than plain SHA.
Frequently asked questions
Why no MD5?
The browser's built-in crypto API does not support MD5, and MD5 is no longer considered secure.
Can a hash be reversed?
No, hashing is one-way, although short and common inputs can be guessed.
