Root Certificates

For communication encrypted with TLS, root certificates are used to verify the
authenticity of the communication partner.
A root certificate, which is signed by a certificate authority, serves to verify the
validity of all certificates issued by this certificate authority.
The root certificates stored on the controller (root CA bundle) form the basis for
authentication of services hosted on the Internet (e.g., email providers and cloud
services).
The standard storage location for the root certificates is /etc/ssl/certs/ca-
certificates.crt.
This file contains the certificates provided by Mozilla. A list of the included root
certificates and their respective validity periods can be requested from the
following address:
https://hg.mozilla.org/releases/mozilla-release/raw-
file/79f079284141/security/nss/lib/ckfw/builtins/certdata.txt
The root certificates can be updated on the controller by updating the file
/etc/ssl/certs/ca-certificates.crt (see section "Service" > "Updating Root
Certificates").
