I'm running a script, that checks the configuration changes between the saved and running config. I have noticed, that the hash that goes after

crypto pki certificate chain TP-self-signed-34586112
certificate self-signed 01

Has changed after a reboot. Is it normal? Why does the hash change after a reboot?

Regards

Yes this is normal. On a Cisco device, a self-signed certificate is not persistent by default. In other words on every reboot it generates a new keypair and a new certificate.

To configure a persistent certificate see Persistent Self-Signed Certificates.
