Title: Can't decrypt anyones PGP Message but my own..
Post by: nplv123 on May 01, 2013, 07:53 am
So I installed GPA (or GNU Privacy Asistant, or GPG4Win or whatever its called....) I managed to create a public key and when i type something into the clipboard i can encrypt and decrypt anything fine. When I encrypt something with a public key from anyone that I've imported myself it gives me a PGP Message block, however if I go to decrypt it I get an error message that says "'Clipboard' contained no valid encryption data." What am I not doing right? Thanks..

Well it's kinda logic that you can't decrypt others pgp messages if they're encrypted with THEIR public key. what would be the point then ?

i was just thinking if i could encrypt it, i should be able to decrypt it, but yeah i guess that would be pretty pointless haha

Yes, you can encrypt it because you have their public key. To decrypt a message, you need a private key ;)

Here is a basic, simple guide I wrote on how to use GPA, which should help you out if your using a Windows system (Gpg4win)

1. Copy the Public Key of the person you want to send a message to.

2. Open a text editor, such as Notepad, and paste the Public Key. Name the file and save it to your desired location on your PC.

3. Open GPA (Gpg4win), click IMPORT, locate the file you just saved with the Public Key in it, and double click it. It will then show up in KEY MANAGER where it is stored for future use along with any other Public Keys you wish to keep.

4. Then click on CLIPBOARD, the 2nd icon in from the right at the top of the page. Type the message you wish to send to the recipient and then click ENCRYPT. Click on the Public Key of the person your sending the message to (should now be highlighted), then click OK at the bottom.

5. Then copy the encrypted message and paste it in a PM to the recipient and send it.

6. REMEMBER - Include your Own Public Key in this message if you wish to receive an encrypted response from the recipient. You can find this by RIGHT-CLICKING your key in KEY MANAGER, then copy/pasting it. :)
