What is a hash function?
A cryptographic hash turns any input into a fixed-length fingerprint that's quick to compute but practically impossible to reverse. Hashes are used for checksums, data integrity, deduplication and storing password digests. This tool computes SHA hashes with the browser's Web Crypto API and MD5 via SparkMD5 — all locally.

Frequently asked questions
Should I use MD5 or SHA-1 for security?
No. MD5 and SHA-1 are broken for security uses; prefer SHA-256 or stronger. MD5/SHA-1 remain fine for non-security checksums.
Can I reverse a hash here?
No — hashing is one-way. This tool only computes hashes, it doesn't crack them.
Is my text uploaded to hash it?
No. Hashing happens in your browser using the Web Crypto API.
