Hash Generator
MD5, SHA-1, SHA-256, SHA-512 hashes
About Hash Generator
Hashes are fingerprints for data: verifying a downloaded file, deduplicating content, storing password digests, or checking whether two files differ. Hash Generator computes MD5, SHA-1, SHA-256 and SHA-512 digests locally in your browser using the Web Crypto API — the file or text you hash never leaves your device.
Paste text or drop a file and the digests appear instantly. Engineers use it to verify checksums, security folks to compare file identity, and students to understand how tiny input changes avalanche into completely different hashes.

Frequently Asked Questions
Which hash algorithm should I use?
SHA-256 is today's default for integrity and general security. MD5 and SHA-1 are fast but cryptographically broken — fine for checksums, never for signatures.
Can a hash be reversed to get the original?
No. Hashing is one-way. The only attack is brute-forcing candidates and comparing digests, which is why strong, unique passwords remain safe.
Is my file uploaded for hashing?
No. Hashing runs in your browser with the Web Crypto API. Files of any size stay on your machine.
Why do the same MD5 and SHA-256 values differ?
Each algorithm produces a different digest length and mixing function — the same input yields different-looking (but equally valid) fingerprints per algorithm.
