Title: Easy PGP question, where does my public key go?
Post by: Getliquid on July 24, 2011, 07:15 am

When I send a message encrypted with the receivers public key, where do I put my key? Do I put my public key inside the encrypted message? Or do I paste it after the encrypted message? I've been pasting it after the encrypted message, just wanted to make sure that was correct. Thanks

Either will work for the purposes of pure communication.

But you should put it inside the encrypted message. This will mean that only the person you're messaging will be able to respond to you with an encrypted reply, because only they can decrypt your message to get your key.

Putting it outside your encrypted message would mean that anyone who intercepted your message could send you an encrypted message, and you may be fooled into thinking it was from the 'real' person.

That's why both sides should ALWAYS sign their messages as well in addition to encrypting the message. This way you know it really came from whoever you recieved the message from. ;)

I usually post it under my encrypted message if I expect a reply or is the first time I've used PGP with a new person.

Best practice is at the end of the plain text before you encode.
This keeps it all together and hides the sender identity from everyone but the intended recipient.

Best Practice is Best! :D

Do any of you have experience with Thunderbird/enigmail?

I was able to use everything properly, and for some reason now I get a error message
when I try to encrypt a message, and the messages will not send what so ever
unless they are unencrypted.

Any help would be great.
