CcfReceipt.cs

CcfReceipt class which enables encoding, decoding and verification of receipts issued from the Signing Transparency Service. This class encapsulates the representation and the available operations of CBOR encoded CCF SCITT receipts. This is a reference implementation for a proposed draft IETF specification: https://datatracker.ietf.org/doc/draft-birkholz-scitt-receipts/03/ .

Methods

Name	Description
GetRegistrationTransactionId(Byte[])	Extracts the registration transaction id (the entry id) from a raw CCF SCITT receipt. The id is encoded in the internal-evidence field of the inclusion proof leaf as the second ':'-separated field (for example, ce:2.15:... yields 2.15).
