If you are an approved Issuer, this is where you enter the credentials that you are issuing to your recipients. You will only have access to files that YOU have issued and you may manage those files, update their status as well as sign and verify them.
If you are a Validator, will have access to all files in a Read Only capacity but you may also verify signed files.
If you are a recipient, you will have access to all files issued to you, save your own files, and you can manage everything except signing of files.
