Use this operation to create a new signature request.
The properties id, created and lastModified are read-only and so must not be provided: they are managed by the platform and added to the returned request.
Only the properties name and hashToSign are required: the hashToSign property must be the SHA256 hash of the file to sign.
Be sure to have enough signature and anchoring credits on your account to fulfill the signature request (each registered signature costs you 1 signature and 1 anchoring credit).
