Today we had a problem at work on a system.
|
||
|
|
Without getting into too much detail as to give away secrets behind the verbal NDA I am behind, I will just say that it had to do with a GPG public key of mine that was expired on a dev machine, accidentally propagating during install to a production machine.
|
||
|
|
This key had a sub key as well, so figuring out this was tricky.
|
||
|
|
|
||
|
|
To start, you can list your gpg keys like so:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ gpg --list-keys
|
||
|
|
|
||
|
|
|
||
|
|
This will list keys such as
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
pub 4096R/01A53981 2011-11-09 [expires: 2016-11-07]
|
||
|
|
uid Tyrel Anthony Souza (Five year key for email.)
|
||
|
|
sub 4096R/C482F56D 2011-11-09 [expires: 2016-11-07]
|
||
|
|
|
||
|
|
To make this not expire, (same steps to change expiration date to another time), you must first edit the key
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ gpg --edit-key 01A53981
|
||
|
|
|
||
|
|
|
||
|
|
You will then see a gpg prompt ``gpg>``
|
||
|
|
|
||
|
|
Type "expire" in and you will be prompted for how long to change it to
|
||
|
|
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
Changing expiration time for the primary key.
|
||
|
|
Please specify how long the key should be valid.
|
||
|
|
0 = key does not expire
|
||
|
|
<n> = key expires in n days
|
||
|
|
<n>w = key expires in n weeks
|
||
|
|
<n>m = key expires in n months
|
||
|
|
<n>y = key expires in n years
|
||
|
|
|
||
|
|
You are then done setting the expiration on the primary key, if you have sub key, doing this is as easy as typing ``key 1`` and repeating the expiration step.
|
||
|
|
|
||
|
|
To finish and wrap things up, type ``save`` and you are done.
