register - command to register set-top-box identity with signer

It connects to
a machine configured to sign certificates,
and obtains an authenticated certificate based on the contents of

The certificate is saved in the file
for later use.

There are several phases to obtaining the certificate.
The register command interacts with

to construct the certificate. This certificate is `blinded' by a random bit mask, sent back to

Once the agent is convinced that the `blinded' certificate has been delivered to the correct party, the agent tells
to accept the identity of the caller.

This step can only validly be performed after the successful
