Detailed Description

A context that can be used to customize the signing process.

It also enables the deferred (aka "async") signing, which is a mean to separately process the intermediate results of signing (normally a hash to sign) that doesn't require a streamlined event based processing. It can be issued by starting the process with StartSigning() and finishing it with FinishSigning()
