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

I want a linux gpg command to remove the passphrase or to export unprotected keys.

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. (Leave this blank and press Enter)

• 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

Let me share what I found. I thought I might share in case there is another lost soul In the bash shell,

gpg2 --batch --gen-key <<EOF
%no-protection
Key-Type:1
Key-Length:2048
Subkey-Type:1
Subkey-Length:2048
Name-Real: My super name
Name-Email:
Expire-Date:0
EOF

The key can now be exported

gpg2 --export-secret-key fingerprinthere > private-key.key
gpg2 --export fingerprintshuld_be_put_here > public-key.key

It's simple. Just run:

gpg --edit-key <yourkeyhere>
passwd

When GnuPG prompts for the new passphrase, just leave it blank and hit enter.
