About this tool

Hash functions create fixed-length fingerprints of data. SHA-256 is today's standard for integrity checks and deduplication; SHA-1 is legacy (avoid for security). SHA digests use your browser's native Web Crypto API; MD5 (still required by many file-integrity and legacy systems) is computed with a local implementation — everything stays offline.

FAQ

Is MD5 safe?

MD5 is fine for checksums and legacy compatibility but broken for security — use SHA-256 there.

Can a hash be reversed?

No — hashes are one-way. Identical input always gives the identical hash.

What are hashes used for?

File integrity checks, deduplication, change detection, password storage (with salting/KDFs).
