Detailed Description

Holds SignatureInfo and SignatureValue in a Data packet.

A Signature is not a TLV element itself. It collects SignatureInfo and SignatureValue TLV elements together for easy access. In most cases, an application should use a subclass of Signature such as DigestSha256 , SignatureSha256WithRsa , or SignatureSha256WithEcdsa instead of using Signature type directly.
