Hello,

 

You can use an ifile. It is stored on the filesystem (in clear) but not in the configuration file. You can use a script and the cron to generate your keys within ifiles.

 

Or alternatively, you can set up a temporary key within a session table : https://devcentral.f5.com/wiki/irules.table.ashx

 

The issue with table is that it doesn't persist accross reboot. You can create your keys using commands within irules. But I'm not sure that you have the right command available to generate a cryptographically secured key.
