Nemokama File Hash / Checksum

Compute SHA-256, SHA-1, SHA-384, and SHA-512 checksums of any file and verify a download against its published hash. The file is never uploaded.

Compute SHA-256, SHA-1, SHA-384, and SHA-512 checksums of any file — and verify a download against its published hash. The file is read locally and never uploaded.

Kaip tai veikia

A checksum is a fingerprint of a file. Publishers list one next to a download so you can confirm the file you got is exactly the one they released — not corrupted or tampered with. This computes them in your browser.

1
You pick a file
It's read into memory locally — never uploaded, no matter the size.
2
Web Crypto hashes it
The browser's native crypto.subtle computes SHA-256, SHA-1, SHA-384, and SHA-512 in a single pass over the bytes.
3
You compare to the published hash
Paste the checksum from the download page; it's matched against all four algorithms and a clear ✓/✗ tells you if the file is authentic.
4
Copy any hash
Grab a checksum to publish alongside your own files.

Verifying a sensitive download (an installer, a disk image, a backup) shouldn't require uploading it anywhere. The hash is computed entirely on your device with native browser crypto.
