==============
|
|
|
|
Starting from version 0.7.5, poezio offers some options to check the validity
|
|
of a X.509 certificate.
|
|
|
|
TOFU
|
|
----
|
|
|
|
The default handling method is the
|
|
link:https://en.wikipedia.org/wiki/User:Dotdotike/Trust_Upon_First_Use[TOFU/TUFU]
|
|
method. At your first connection, poezio will save the hash of the certificate
|
|
received, and will compare the received one and the first one for the next
|
|
connections.
|
|
|
|
|
|
If you are paranoid (or run poezio for the first time in an unsafe
|
|
environment), you can set the _certificate_ value of your config file yourself
|
|
(the hash, not colon-separated).
|
|
|
|
|
|
If the certificate is not the same, poezio will show an error message and wait
|
|
for confirmation:
|
|
|
|
image:../images/ssl_warning.png["Warning message", title="Warning message"]
|
|
|
|
If you press y, the change is validated an poezio will match the next certs
|
|
with the accepted one.
|
|
|
|
If you press n, you will get the confirmation that the change has been
|
|
refused, and you will be disconnected.
|
|
|
|
CA-Based
|
|
--------
|
|
|
|
If you are connecting to a large server that has several front-facing
|
|
endpoints, you might be bothered by having to validate the change each time,
|
|
and you may want to check only if it the same authority delivered the
|
|
certificate.
|
|
|
|
You can then set the _ca_cert_path_ option to the path of a file containing
|
|
the validation chain in link:https://tools.ietf.org/html/rfc1422.html[PEM
|
|
format] ; those certificates are usually in /usr/share/ca-certificates/ but it
|
|
may vary depending of your distribution.
|
|
|
|
If the authority does not match when connecting, you should be disconnected.
|
|
|
|
None
|
|
----
|
|
|
|
If you do not want to bother with certificate validation at all (which can be
|
|
the case when you run poezio on the same computer as your jabber server), you
|
|
can set the _ignore_certificate_ value to true, and let the _ca_cert_path_
|
|
option empty (or even remove it).
