Hash Calculation and Verification

Confirms that a file you downloaded is identical to the one the publisher released. Select a file and choose Compute and verify hash from More ▶ in the context menu. Calculation starts as soon as the window opens.

  • Algorithms: SHA-256 (default), SHA-1, MD5 and CRC-32. Folders are not included.

  • Verifying against a pasted value: Paste the hash published on the download page into the field at the top and the result appears immediately. The algorithm is detected from the length of what you pasted, so there is nothing to select by hand. Case and surrounding whitespace are ignored. Values followed by a file name (sha256sum output), values with a SHA256: label, values split into groups by spaces, and values separated by - or : can all be pasted as they are.

  • Comparing two files: Select exactly two files and the window reports whether their contents are identical. This holds even when their names or timestamps differ.

  • Multiple files: Any number of files can be processed at once. Copy puts the results on the clipboard as file name <TAB> hash, ready to paste into a spreadsheet.

  • Large files: A multi-gigabyte file is never loaded into memory in full. A progress bar is shown while the work runs and Stop ends it at any point. If a file cannot be read, only that row shows the reason and the remaining files are still processed.
