KeyTransRecipientInfo Class

The KeyTransRecipientInfo class defines key transport recipient information. Key transport algorithms typically use the RSA algorithm, in which an originator establishes a shared cryptographic key with a recipient by generating that key and then transporting it to the recipient. This is in contrast to key agreement algorithms, in which the two parties that will be using a cryptographic key both take part in its generation, thereby mutually agreeing to that key.

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

public ref class KeyTransRecipientInfo sealed : public RecipientInfo

The KeyTransRecipientInfo type exposes the following members.

  NameDescription
Public propertyEncryptedKeyThe EncryptedKey property retrieves the encrypted key for this key transport recipient. (Overrides RecipientInfo::EncryptedKey.)
Public propertyKeyEncryptionAlgorithmThe KeyEncryptionAlgorithm property retrieves the key encryption algorithm used to encrypt the content encryption key. (Overrides RecipientInfo::KeyEncryptionAlgorithm.)
Public propertyRecipientIdentifierThe RecipientIdentifier property retrieves the subject identifier associated with the encrypted content. (Overrides RecipientInfo::RecipientIdentifier.)
Public propertyTypeThe 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.)
Public propertyVersionThe Version property retrieves the version of the key transport recipient. The version of the key transport recipient is automatically set for objects in this class, and the value implies that the recipient is taking part in a key transport algorithm. (Overrides RecipientInfo::Version.)

  NameDescription
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns 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.

NoteNote

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.
