KeyTransRecipientInfo Class

Definition

Namespace:

System.Security.Cryptography.Pkcs

Assembly:

Source:

KeyTransRecipientInfo.cs

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.

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

EncryptedKey	The EncryptedKey property retrieves the encrypted key for this key transport recipient.
KeyEncryptionAlgorithm	The KeyEncryptionAlgorithm property retrieves the key encryption algorithm used to encrypt the content encryption key.
RecipientIdentifier	The RecipientIdentifier property retrieves the subject identifier associated with the encrypted content.
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 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.

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)
