1 A short installation guide.

Unfortunately the installation guide has not been finished in time. Instead of delaying the release of GnuPG 2.0 even further, I decided to release without that guide. The chapter on gpg-agent and gpgsm do include brief information on how to set up the whole thing. Please watch the GnuPG website for updates of the documentation. In the meantime you may search the GnuPG mailing list archives or ask on the gnupg-users mailing listsfor advise on how to solve problems or how to get that whole thing up and running.

Such questions may also help to write a proper installation guide.

XXX Tell how to setup the system, install certificates, how dirmngr relates to GnuPG etc.

** Explain how to setup a root CA key as trusted

X.509 is based on a hierarchical key infrastructure. At the root of the tree a trusted anchor (root certificate) is required. There are usually no other means of verifying whether this root certificate is trustworthy than looking it up in a list. GnuPG uses a file (trustlist.txt) to keep track of all root certificates it knows about. There are 3 ways to get certificates into this list:

• Use the list which comes with GnuPG. However this list only contains a few root certifciates. Most installations will need more.
• Let gpgsm ask you whether you want to insert a new root certificate. To enable this feature you need to set the option allow-mark-trusted into gpg-agent.conf. In general it is not a good idea to do it this way. Checking whether a root certificate is really trustworthy requires a decsions, which casual usuers are not up to. Thus, by default this option is not enabled.
• Manually maintain the list of trusted root certificates. For a multi user installation this can be done once for all users on a machine. Specific changes on a per-user base are also possible.

XXX decribe how to maintain trustlist.txt and /etc/gnupg/trustlist.txt.
