signing kernel modules on RHEL 7

[Chakradhar thota]

Hello Everyone,

I have compiled kernel module on RHEL7 but when I insert the module, I
got following warning

"module verification failed: signature and/or required key missing -
tainting kernel".

I tried signing the module on custom kernel and find it working.
How can we sign the module for a target system with standard RHEL distribution?
where can we find keys for signing the module on standard kernel?

Regards,
Chakradhar
