Frequently Asked Questions

What is a hash function?+

A one-way function turning any input into a fixed-length fingerprint. The same input always yields the same hash, but the hash can't be reversed into the input.

Which algorithm should I use?+

SHA-256 is today's standard for integrity checks and signatures. MD5 and SHA-1 are broken for security purposes but still fine as simple checksums and cache keys.

What are hashes used for?+

Verifying file integrity, deduplicating data, cache keys, digital signatures and comparing values without storing the originals.

Is my input sent anywhere?+

No — hashing runs entirely in your browser, which matters when hashing anything sensitive.
