How do I change my self signed device certificate and at the same time upgrade from 1024 to 2048 bits ?. Using the Gui doesn't allow me to change the size to 2048

Hi,

 

you can use this command to create the new Certificate with key:

 

openssl req -x509 -nodes \ -days 3650 \ -newkey rsa:2048 \ -keyout /config/httpd/conf/ssl.key/server.key \ -out /config/httpd/conf/ssl.crt/server.crt \ -subj /C=FR/\ O=Company/\ CN=bigip1.f5demo.com/\ L=My\ City/\ ST=My\ State

Then restart httpd service:

 

bigstart restart httpd
