The Section 220.127.116.11, “Signature Checking Using GnuPG” section describes
how to verify MySQL downloads using GPG. That guide also applies
to Microsoft Windows, but another option is to use a GUI tool
like Gpg4win. You
may use a different tool but our examples are based on Gpg4win,
and utilize its bundled
Download and install Gpg4win, and then load Kleopatra. The dialog should look similar to:
