About
Hash computes cryptographic hashes — MD5, SHA-1, SHA-256, SHA-384, SHA-512, and CRC32 — of either typed text or an uploaded file, streaming large files in chunks rather than loading them fully into memory. All algorithms run at once by default, so you get every hash of the same input in one pass instead of switching and recomputing. Files are hashed entirely in your browser; nothing is uploaded to verify a checksum.
Frequently asked
- Can it hash a large file without uploading it?
- Yes — hashing runs entirely client-side, streaming the file in chunks, so even large files are hashed without ever leaving your device.
- Which hash algorithms does it support?
- MD5, SHA-1, SHA-256, SHA-384, SHA-512, and CRC32, computed for the same input simultaneously so you don't have to pick one first.
