@RavinderReddyF5 I'm not sure if this is a good approach here, providers shouldn't be accessing artifacts (i.e. files) on the disk directly, instead the content should be either stored in the config in the form of a heredoc in a variable or loaded by terraform itself using the file(path) function and content stored in the state from which the provider will retrieve it.
an example for this is how irule content is currently implemented, you can define the irule code in a variable (heredoc) or load it from a file (file(irule.tcl)) and it's very useful and flexible.
allowing the provider to read file content directly doesn't seem like the optimal approach here since it limits some of the flexibility that terraform provides when working with this kind of content.
Bu getting the certificate from state through terraform config (variable with heredoc content or file(path)) you achieve the same with better flexibility to the end user.
