Requirement of key size for code signing certificate to sign modules

[manisha.bansal]

Can we get to know

1. What is the optimal key size for a code signing certificate (leaf)?
2. What is the requirement for key size for ROOT of this signing cert?
3. What are the requirements around using a self-signed cert?

I have used 2048 size for a standard openssl generated certificate with the code signing usage added. AlI I did was generate the certificate, add it to a java keystore and use the code signing tool with these items.

It doesn't really matter at all. Just self sign something.

Module signing is pretty meaningless, there is no real advantage to using a publicly trusted certificate for signing Ignition modules. Just have your company generate a certificate from their CA or use a self-signed certificate.
