WebCrypto GOST: Class: AuthenticatedData

Constructor

new AuthenticatedData()

The authenticated-data content type consists of content of any type, a message authentication code (MAC), and encrypted authentication keys for one or more recipients. The combination of the MAC and one encrypted authentication key for a recipient is necessary for that recipient to verify the integrity of the content. Any type of content can be integrity protected for an arbitrary number of recipients.


     AuthenticatedData ::= SEQUENCE {
       version CMSVersion,
       originatorInfo [0] IMPLICIT OriginatorInfo OPTIONAL,
       recipientInfos RecipientInfos,
       macAlgorithm MessageAuthenticationCodeAlgorithm,
       digestAlgorithm [1] DigestAlgorithmIdentifier OPTIONAL,
       encapContentInfo EncapsulatedContentInfo,
       authAttrs [2] IMPLICIT AuthAttributes OPTIONAL,
       mac MessageAuthenticationCode,
       unauthAttrs [3] IMPLICIT UnauthAttributes OPTIONAL }

     AuthAttributes ::= SET SIZE (1..MAX) OF Attribute

     UnauthAttributes ::= SET SIZE (1..MAX) OF Attribute

     MessageAuthenticationCode ::= OCTET STRING
