Expand description

The KeyAgreeRecipientInfo type is defined in RFC 5652 Section 6.2.2.

  KeyAgreeRecipientInfo ::= SEQUENCE {
      version CMSVersion,  -- always set to 3
      originator [0] EXPLICIT OriginatorIdentifierOrKey,
      ukm [1] EXPLICIT UserKeyingMaterial OPTIONAL,
      keyEncryptionAlgorithm AlgorithmIdentifier
          {KEY-AGREE, {KeyAgreementAlgorithmSet}},
      recipientEncryptedKeys RecipientEncryptedKeys }
