SYNOPSIS
|
|
|
6cf4d9 |
--------
|
|
|
6cf4d9 |
*ca-legacy* ['COMMAND']
|

DESCRIPTION
|
|
|
6cf4d9 |
-----------
|
|
|
6cf4d9 |
ca-legacy(8) is used to include or exclude a set of legacy Certificate Authority (CA)
|
|
|
6cf4d9 |
certificates in the system's list of trusted CA certificates.
|
|
|
6cf4d9 |
|
|
|
6cf4d9 |
The list of CA certificates and trust flags included in the ca-certificates package
|
|
|
6cf4d9 |
are based on the decisions made by Mozilla.org according to the Mozilla CA policy.
|
|
|
6cf4d9 |
|
|
|
6cf4d9 |
Occasionally, removal or distrust decisions made by Mozilla.org might be incompatible with the requirements
|
|
|
6cf4d9 |
or limitations of some applications that also use the CA certificates list in the Linux environment.
|
|
|
6cf4d9 |
|
|
|
6cf4d9 |
The ca-certificates package might keep some CA certificates included and trusted by default,
|
|
|
6cf4d9 |
as long as it is seen necessary by the maintainers, despite the fact that they have
|
|
|
6cf4d9 |
been removed by Mozilla. These certificates are called legacy CA certificates.
|
|
|
6cf4d9 |
|
|
|
6cf4d9 |
The general requirements to keep legacy CA certificates included and trusted might change over time,
|
|
|
6cf4d9 |
for example if functional limitations of software packages have been resolved.
|
|
|
6cf4d9 |
Future versions of the ca-certificates package might reduce the set of legacy CA certificates
|
|
|
6cf4d9 |
that are included and trusted by default.
|
|
|
6cf4d9 |
|
|
|
6cf4d9 |
The ca-legacy(8) command can be used to override the default behaviour.
|
|
|
6cf4d9 |
|
|
|
6cf4d9 |
The mechanisms to individually trust or distrust CA certificates as described in update-ca-trust(8) still apply.
