How To Change The Zentyal Certificate Algorithm From SHA-1 To SHA256

Posted on by Mozi

As of Zentyal version 4.2 the bundled certificate authority (CA) module is creating signed certificates using the SHA-1 algorithm which is an old algorithm and pretty much deprecated.

Google Chrome, for example, will give a warning when accessing any SSL page that’s encrypted stating that your connection is not secure.

SSL Certificates created now should, as a minimum, use the the SHA256 algorithm to ensure encrypted connections are kept private. To change Zentyal to use the SHA256 algorithm, you’ll need to make a small edit to your openssl.cnf file.

default_md = sha1

Edit the value and enter sha256.

default_md = sha256

You’ll then need to log into the Zentyal Admin site and revoke and re-issue all of your sha1 certificates.

Problem with 3.16.0-48-generic. I did this and rebooted and it worked:

Code: Select all
    dkms remove -m ctn91xx -v 2013_0326_2226 --all
    dkms add -m ctn91xx -v 2013_0326_2226
    dkms build -m ctn91xx -v 2013_0326_2226
    dkms install -m ctn91xx -v 2013_0326_2226

White plug with a rubber boot on it.  Jump the pins above (note orientation of plug, key up)

Turn on the ignition (no need to start engine) and codes will display on speedometer LCD.

When you look into the odometer box and see the code, e.g. C46 (EXCVA – exhaust control valve), just to the left of the code will be a hash mark. That represents the position of the throttle open percentage/position. If you then open up your throttle, the hash mark will move up screen to represent the increasing open position of the throttle. If it is moving appropriately, that is supposed to mean that your throttle is working ok.

clean up /boot
