How can I sign my update with PGP and send it?
The most straightforward way is to use gpg from the command line. The following steps will help you accomplish this:
- Write your update to a file (say, update.txt).
- Sign this file with the command gpg --clearsign update.txt. You'll be required to enter the passphrase. Then gpg will create a file update.txt.asc which contains the signed version of update.txt.
- Mail update.txt.asc to auto-dbm _at_ ripe _dot_ net.
You can also use your mailer software facilities to do this which is mostly a menu entry. Please see the documentation of the particular software for this.
