with which key i have to sign a mail (mine or foerign)

Post by unleash_it » Sun Jun 29, 2014 8:01 am

a friend sent me his public key

note: i have pgp on opensuse 13.1 running with kgpg -

and i have generated a keyset.


now i want to send a crypted email to my friend

question: with which key i have to sign a mail : with mine or the key of my friend - that is the one that receives the e-mail.

in other words: when i open the editor of Kgpg - and paste the message-text into the editor - i subsequently have to sign this: with which keys i do that.

- with mine (that is corresponding to my mail ? - or
- with one that corresponds to his maiil adreess?


need to know that. if i have to write more - let me know..

thanks in advance

You've to encrypt the message to your friend using his public key.
He'll be the only one able to de-crypt & read it using his private key.

You can also use OpenPGP to encrypt email. And if you are using Thunderbird email client, there's a addon called "Enigmail" to manage a public key address book & encrypt/de-crypt messages.
