About this tool
Hash Generator computes SHA-2 digests of anything you type or any file you drop in, using the browser's native Web Crypto implementation — fast and correct. Hashing files is the classic way to verify downloads: compare the digest against the publisher's published checksum.
Output is lowercase hex, ready to copy. Files are read locally and never uploaded, so even sensitive documents are safe to hash.
How to use
- Type text or drop a file into the uploader.
- Select SHA-256, SHA-384, or SHA-512.
- The hex digest computes automatically.
- Copy the hash or compare it against a known checksum.
Frequently asked questions
SHA-256 is the standard choice for checksums and general use. SHA-384/512 offer larger digests; use them when a spec or counterpart requires them.
No — cryptographic hashes are one-way. The only "reversal" is guessing inputs and re-hashing (which is why passwords need salting and slow hashes, not plain SHA).
A matching hash proves the file arrived intact and unmodified — it catches both corruption and tampering.
No. Files are hashed locally in your browser.
