What GUI (no command line) software or websites can I use to verify a PGP signature?

If I have a message like this

Hash: SHA1

Because anyone can claim to be me. There's no validation of the user
name or email address when someone posts a comment. While I do try to
remove imposters, some may slip through. By signing my comments using
this technique, anyone can independently verify that I was the author of
the message by validating the signature.
Version: GnuPG v1.4.6 (MingW32)


How can I verify the message against the public key to get the same signature back?

This online encryption/decryption PGP site does not allow me to do that.

    Have you tried GPG4Win ? From what I remember it does certify OpenPGP certificates

    GPG4Win Kleopatra doesn't open on my computer.

    I'd been looking for a program for this as well. When using GPGshell along with GPG4Win, I found GPGtray. Open it, right click the tray icon, and select "View/Edit Clipboard". Here you'll find a full GUI for applying any PGP operation to plain text, including signing and verifying. Mar 18, 2016 at 1:32

Here's a short list GUIs that let you verify PGP clear-signed messages [which I've personally used and can vouch for].


If you use the old version of PGP version 6, not the new version 8, you'll find a GUI interface that lets you store PGP keys and encrypt text, decrypt text and verify signatures with timestamps.

Here's the download link I've uploaded for version 6.

    Think twice before following the link. At best it does what it says. But what if instead it is a malware that takes your PGP keys or that corrupts your PGP binaries?

  • I got the download from the official PGP company before Symantec brought it. It's a safe link.

    No matter if you vouch for the safety of your download link, @desbest, it's still very poor security practice to download any program (especially a cryptography program) from an unverified source such as those you have provided.

Here is an extensive list of OpenPGP GUI software for many OS: https://openpgp.org/software

The list is referring to Email Encryption. But e.g. GPG Suite for macOS comes with the free to use GPG Services integrating into the macOS Services menu and allowing for text and file verification. Gpg4win offers a GUI solution to get this done on Windows
