14.04gnupgpgpseahorse
I am trying to get seahorse-daemon (formerly seahorse-agent) to cache the passphrase for private pgp keys permanently.
I have used dconf-editor to set "gpg-cache-method" to always, but the setting is ignored, seahorse prompts for passphrase entry every time the key is used.
Interestingly I have six machines all running 14.04 with latest updates, and I can't figure out why some of them do cache the passphrase permanently while others don't.
Thanks in advance for any ideas.
I do not think you can do all of the steps with Seahorse and the seahorse plugins do not seem to be maintained beyond 11.04.
Create a gpg key
Start seahorse , under the main menu New -> Create a new GPG key
Fill in the subsequent information and password
2) Download the PGP key from Truecrypt You can do this with any browser, save the file where you wish. For this tutorial I will use Downloads in your home directory.
http://www.truecrypt.org/downloads2
The file is called "TrueCrypt-Foundation-Public-Key.asc"
https://www.truecrypt.org/download/TrueCrypt-Foundation-Public-Key.asc
3) With seahorse, import and sign the key
In the seahorse menu -> File -> Import
Select the truecrypt key ( "TrueCrypt-Foundation-Public-Key.asc" )
Now sign the key as trusted
Under the "other" tab, select the truecrypt key and sign it as trusted
4) Download the truecrypt PGP signature from here, save it in Downloads
http://www.truecrypt.org/downloads
5) As far as I know, you can only verify the signature from the command line
cd ~/Desktop
~/Desktop$ gpg truecrypt-7.1a-linux-x86.tar.gz.sig --verify truecrypt-6.2a-ubuntu-x86.tar.gz
Should yield
gpg: Good signature from "TrueCrypt Foundation "

dconf-editor.gpg-cache-method to idle or timeout.gpg-cache-ttl to the number of seconds you want the passphrase to be cached.$ gnome-keyring-daemon -ridle means that the timer is reset each time you use the key before timeout is reached. timeout means that simply the time elapsed since entering the passphrase is considered.
This only works for GPG-keys. Passphrases for SSH-keys are still cached until the end of the session. IMHO this is a bug.

To permanently save the a passphrase in the keyring, use
seahorse-ssh-askpassfrom packageseahorse:Note: You have to have a have the corresponding
.pubfile in the same directory as the private key (~/.ssh/id_rsa.pubin the example). Also, make sure that the public key is the file name of the private key plus.pub(for example,my_key.pub).
