The 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.

Thetype exposes the following members.
|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. (Overrides RecipientInfo.EncryptedKey.)|
|KeyEncryptionAlgorithm||The KeyEncryptionAlgorithm property retrieves the algorithm used to perform the key agreement. (Overrides RecipientInfo.KeyEncryptionAlgorithm.)|
|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. (Overrides RecipientInfo.RecipientIdentifier.)|
|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. (Overrides RecipientInfo.Version.)|
|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.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
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.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
