14 ** Explain how to setup a root CA key as trusted
16 X.509 is based on a hierarchical key infrastructure. At the root of the
17 tree a trusted anchor (root certificate) is required. There are usually
18 no other means of verfying whether this root certificate is trutsworthy
19 than looking it up in a list. GnuPG uses a file (@file{trustlist.txt})
20 to keep track of all root certificates it knows about. There are 3 ways
21 to get certificates into this list:
25 Use the list which comes with GnuPG. However this list only
26 contains a few root certifciates. Most installations will need more.
29 Let @command{gpgsm} ask you whether you want to insert a new root
30 certificate. To enable this feature you need to set the option
31 @option{allow-mark-trusted} into @file{gpg-agent.conf}. In general it
32 is not a good idea to do it this way. Checking whether a root
33 certificate is really trustworthy requires a decsions, which casual
34 usuers are not up to. Thus, by default this option is not enabled.
37 Manually maintain the list of trusted root certificates. For a multi
38 user installation this can be done once for all users on a machine.
39 Specific changes on a per-user base are also possible.
42 XXX decribe how to maintain trustlist.txt and /etc/gnupg/trustlist.txt.
