How to implement 2048 bit DKIM keys on CWP servers.

opendkim-genkey is a perl script. You can open the file /usr/sbin/opendkim-genkey using the text editor like vi, ee, etc and change the value of "bits":

Code: [Select]

my $bits = 1024;
to

Code: [Select]

my $bits = 2048;
right under "Set up defaults".

It will generate 2048bits keys by default.

Please note you do such changed on your own risk.

Or I just do it manually.

You can user the DKIM Generator at:

And then update the files at /etc/opendkim/userkeys/

Or I just do it manually.

As another user wrote the question is:

2048 bit DKIM is the new standard today, developers of CWP and we the users must move toward implementing 2048 bit DKIM out of the box by default.
