PGP KEY RING directories are separeted for each purpose. For example, the keyring dir for article pgp auth is $ml_home_dir/etc/pgp-article-post-auth/ directory, the keyring dir for remote administration by command mail is $ml_home_dir/etc/pgp-admin-command-mail-auth/ directory.

Use pgp2, pgp5 and gpg commands to edit keys under them It is useful to use the following fmlpgp wrapper command. The wrapper sets up proper environment variables.

--article-post-auth       (auth for post article)
--command-mail-auth       (auth for command mail)
--admin-command-mail-auth (auth for admin command mail)
--article-post-encrypt    (article encryption)
