Hash Generator (MD5, SHA-1, SHA-256, SHA-512)
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files. Runs in your browser.
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files. Live updates, copy-to-clipboard, and a verify-against-hash field that lights up green or red when you paste an expected hash to compare. Everything runs locally.
When to use it
- 1Verifying a downloaded file against a published checksum.
- 2Producing content-addressable identifiers for caching.
- 3Quickly hashing a string for a test fixture or stub.
How it works
- 1
Pick text or file
Tab between modes. File mode shows a progress bar for large inputs.
- 2
Read all four hashes
MD5, SHA-1, SHA-256, SHA-512 all compute in parallel and update as you type.
- 3
Verify a known hash
Paste an expected hash into any verify field - green if it matches, red if not.
Frequently asked
Should I use MD5 for security?
No. MD5 and SHA-1 are broken for cryptographic use. Use SHA-256 or SHA-512 for anything that matters.
Are big files supported?
Up to your browser memory. The Web Crypto API streams the digest, so multi-hundred-MB files work on most machines.
