CA-LEGACY(8) CA-LEGACY(8)
NAME
ca-legacy - Manage the system configuration for legacy CA certificates
SYNOPSIS
ca-legacy [COMMAND]
DESCRIPTION
ca-legacy(8) is used to include or exclude a set of legacy Certificate
Authority (CA) certificates in the system's list of trusted CA
certificates.
The list of CA certificates and trust flags included in the
ca-certificates package are based on the decisions made by Mozilla.org
according to the Mozilla CA policy.
Occasionally, removal or distrust decisions made by Mozilla.org might
be incompatible with the requirements or limitations of some
applications that also use the CA certificates list in the Linux
environment.
The ca-certificates package might keep some CA certificates included
and trusted by default, as long as it is seen necessary by the
maintainers, despite the fact that they have been removed by Mozilla.
These certificates are called legacy CA certificates.
The general requirements to keep legacy CA certificates included and
trusted might change over time, for example if functional limitations
of software packages have been resolved. Future versions of the
ca-certificates package might reduce the set of legacy CA certificates
that are included and trusted by default.
The ca-legacy(8) command can be used to override the default behaviour.
The mechanisms to individually trust or distrust CA certificates as
described in update-ca-trust(8) still apply.
COMMANDS
check
The current configuration will be shown.
default
Configure the system to use the default configuration, as
recommended by the package maintainers.
disable
Configure the system to explicitly disable legacy CA certificates.
Using this configuration, the system will use the set of included
and trusted CA certificates as released by Mozilla.
install
The configuration file will be read and the system configuration
will be set accordingly. This command is executed automatically
during upgrades of the ca-certificates package.
FILES
/etc/pki/ca-trust/ca-legacy.conf
A configuration file that will be used and modified by the
ca-legacy command. The contents of the configuration file will be
read on package upgrades.
