Keycroc doesn't trust C2 self signet certificate CA


Recommended Posts

I have set up C2 server and created a self.signed certificate as in this guide:


If have also copied cert.crt to my Keycroc and to file /etc/ssl/cert.pem (as in the guide above). But my Keycroc is not able to form a connection to C2 server. TLS-handshake failure: "Unknown CA".

I also have SharkJack connected to the same server (with same settings) and there is no problem with that one.

Try the following on the Croc:

apt update
apt install p11-kit

trust anchor /etc/ssl/certs/cert.crt

If getting an error like "no configured writable location to store anchors", then import the cert manually by copying the certificate (crt) file to /usr/local/share/ca-certificates

Then execute:

The Croc should show in C2 without need of doing any additional actions (such as reboot, etc.)
