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