RecipientInfo Class

.NET Framework (current version)

The RecipientInfo class represents information about a CMS/PKCS #7 message recipient. The RecipientInfo class is an abstract class inherited by the KeyAgreeRecipientInfo and KeyTransRecipientInfo classes.

Namespace: System.Security.Cryptography.Pkcs
Assembly: System.Security (in System.Security.dll)

Inheritance Hierarchy

System::Object
System.Security.Cryptography.Pkcs::RecipientInfo
System.Security.Cryptography.Pkcs::KeyAgreeRecipientInfo
System.Security.Cryptography.Pkcs::KeyTransRecipientInfo

Syntax

C++

[HostProtectionAttribute(SecurityAction::LinkDemand, MayLeakOnAbort = true)]
public ref class RecipientInfo abstract

Properties

	Name	Description
	EncryptedKey	The EncryptedKey abstract property retrieves the encrypted recipient keying material.
	KeyEncryptionAlgorithm	The KeyEncryptionAlgorithm abstract property retrieves the algorithm used to perform the key establishment.
	RecipientIdentifier	The RecipientIdentifier abstract 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.
	Version	The Version abstract property retrieves the version of the recipient information. Derived classes automatically set this property for their objects, and the value indicates whether it is using PKCS #7 or Cryptographic Message Syntax (CMS) to protect messages. The version also implies whether the RecipientInfo object establishes a cryptographic key by a key agreement algorithm or a key transport algorithm.

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(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.)

Remarks

This is an abstract class that cannot be instantiated. It is inherited by the KeyAgreeRecipientInfo and KeyTransRecipientInfo classes.
