setupSHA.exe (size = 193390, SHA-256 = a1e2cdd120ab226b8d8615450f60c9f175921bb9a7944d86fd06602d9f9fa1da). |
To check SHA-256 signature (e.g. if the file is not changed) one can use Windows certutil utility but this requires som skills, so I have made this easy calculator.
After you download your program, start this calculator, press the [File...] button and pick the program. The file's signatur will be shown in first text box.
Paste the value of SHA-256 from the source site and press [Compare] button.
