File SHA-256

Compute SHA-256 for one file in this tab so you can compare it to the checksum on the vendor’s site. A match means the bytes match — not that the publisher is honest, and not that the file is malware-free.

The download page printed a SHA-256 and you want to know if the installer matches. Uploading the installer to a “checksum website” is backwards. This page hashes one file, SHA-256 only, in a worker on this device.

Hash generator is for typed text. Do not send a binary through that box.

How to verify a download

1. Copy the published hash from the official site (not a random mirror).
2. Drop the file here. Compare, case-insensitive, ignoring spaces.
3. If the file is bigger than about 32 MB, skip this tab:

# Windows PowerShell
Get-FileHash -Algorithm SHA256 .\setup.exe

# Windows CMD
certutil -hashfile setup.exe SHA256

# macOS / Linux
sha256sum setup.iso

Honest limits

• SHA-256 only. No MD5 file mode, no SHA-512 file mode.
• Match ≠ trusted publisher. Compromised sites publish matching hashes for malware.
• We do not scan archives inside the file.

For HMAC of a string plus a key, use HMAC / password check.
