Cmsex.Authenticated (cmsex v0.1.0)

Copy Markdown View Source

An AuthenticatedData message whose MAC Cmsex.verify_mac/2 checked.

Fields:

  • :content - the content the MAC covers, when the message carries it; nil for a detached message, whose content the caller gave.
  • :content_type - its type, as a name of Cmsex.OID, such as :data, or an OID. With authenticated attributes, the content-type attribute was checked against it.
  • :recipient - the Cmsex.RecipientInfo that gave the MAC key, or nil when it came in :mac_key.
  • :message - the Cmsex.AuthenticatedData, for the rest: the authenticated attributes, which the MAC covers, the unauthenticated ones, which it does not, and the originator certificates.

A MAC tells that the content comes from someone who had the MAC key, and was not changed since. Who that is depends on the recipients: see Cmsex.mac/3.
