KeyAgreeRecipientInfo Class

Definition

Namespace:

System.Security.Cryptography.Pkcs

Assembly:

System.Security.Cryptography.Pkcs.dll

The KeyAgreeRecipientInfo class defines key agreement recipient information. Key agreement algorithms typically use the Diffie-Hellman key agreement algorithm, in which the two parties that establish a shared cryptographic key both take part in its generation and, by definition, agree on that key. This is in contrast to key transport algorithms, in which one party generates the key unilaterally and sends, or transports it, to the other party.

Remarks

This class does not have a public constructor; therefore, it cannot be publicly instantiated. It is a read-only class accessible from the EnvelopedCms.RecipientInfos property.

Properties

Date	The Date property retrieves the date and time of the start of the key agreement protocol by the originator.
EncryptedKey	The EncryptedKey property retrieves the encrypted recipient keying material.
KeyEncryptionAlgorithm	The KeyEncryptionAlgorithm property retrieves the algorithm used to perform the key agreement.
OriginatorIdentifierOrKey	The OriginatorIdentifierOrKey property retrieves information about the originator of the key agreement for key agreement algorithms that warrant it.
OtherKeyAttribute	The OtherKeyAttribute property retrieves attributes of the keying material.
RecipientIdentifier	The RecipientIdentifier property retrieves the identifier of the recipient.
Type	The Type property retrieves the type of the recipient. The type of the recipient determines which of two major protocols is used to establish a key between the originator and the recipient of a CMS/PKCS #7 message. (Inherited from RecipientInfo)
Version	The Version property retrieves the version of the key agreement recipient. This is automatically set for objects in this class, and the value implies that the recipient is taking part in a key agreement algorithm.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
