I want to remove the passphrase from gpg key after creating it. Why? .
Because the tigase-kontalk documentation says so and I want to compile and setup my own version of this server . But am stuck at this point

Create GPG key Create a GPG key for both signing and encrypting, and
remove its passphrase after creating it

Here is a more complete answer based on Justin's.

(Using gpg 1.4.16 on Ubuntu 14)

Get the ID of your key like this:

$ gpg --list-secret-keys

This will output a few lines similar to below. The key ID is the value XXXX

 /home/username/.gnupg/secring.gpg
 ----------------------------------
 sec   4096R/XXXX <creation date>
 uid                  name <email.address>
 ssb   4096R/YYYY <creation date>

Open the gpg key edit submenu like this:

gpg --edit-key XXXX

You will see information about the key. Type passwd at the prompt to change the password:

gpg> passwd

Enter your existing passphrase.

Enter the new passphrase for this secret key.

Press Enter twice and consider the warnings from the tool and its implications before proceeding.

You don't want a passphrase - this is probably a *bad* idea!

Do you really want to do this? (y/N) y
