Constructors

Name	Description
EnvelopedData()	Creates an instance of EnvelopedData class. It must be initialized using Load(Stream) or Decode(Byte[]) methods before any other methods and properties can be accessed.
EnvelopedData(ContentInfo)	Creates an instance of SignedData class using the specified content information as the inner content.
EnvelopedData(ContentInfo, ObjectIdentifier)	Creates an instance of EnvelopedData class using the specified content information and encryption algorithm.
EnvelopedData(ContentInfo, ObjectIdentifier, Int32)	Creates an instance of EnvelopedData class using the specified content information and encryption algorithm.

Properties

Name	Description
CertificateFinder	Gets or sets the ICertificateFinder to be used to find certificates corresponding to a SubjectIdentifier.
CertificateRevocationLists	Gets the collection of certificate revocation lists (CRLs) that are embedded in the message.
Certificates	Gets the collection of certificates that are embedded in the message.
ContentEncryptionAlgorithm	Gets the identifier of the algorithm used to encrypt the content.
ContentInfo	Gets the inner content information for this CMS/PKCS #7 message. It contains the content type identifier and content data.
HasPrivateKey	Returns a value indicating whether the private key to decrypt the symmetric key and encrypted content is available.
IsEncrypted	Gets a value indicating whether the content is encrypted.
RecipientInfos	Gets the collection of recipients associated with this CMS/PKCS #7 message.
Silent	Gets or sets a value indicating whether cryptographic providers are allowed to display any user interface (UI) when working with private keys.
UnprotectedAttributes	Gets the collection of unprotected (unencrypted) attributes associated with this CMS/PKCS #7 message.
UseDer	Gets or sets a value indicating whether to use DER encoding rules when encoding SignedData.

Methods

Name	Description
AcquirePrivateKey()	Tries acquiring a private key unless it is already available.
Clone()	Creates a copy of this object.
Decode(Byte[])	Decodes an encoded CMS/PKCS #7 encrypted message from raw data. Upon successful decoding, information can be retrieved using EnvelopedData methods and properties.
Decrypt()	Decrypts the contents of the CMS/PKCS #7 message.
Encode()	Encodes the EnvelopedData object into CMS/PKCS #7 message data.
Encrypt()	Encrypts the contents of the CMS/PKCS #7 message.
GetSymmetricAlgorithm()	Gets the symmetric algorithm used to encrypt or decrypt the content, or null if it cannot be retrieved.
GetSymmetricKey()	Gets the symmetric key used to encrypt the message, or null if it cannot be retrieved.
IsEnvelopedData(Byte[], Int32, Int32)	Determines whether the specified content info ASN.1 sequence is an enveloped data sequence.
Load(Stream)	Loads a CMS/PKCS #7 encrypted message from a stream. Upon successful decoding, information can be retrieved using EnvelopedData methods and properties.
LoadSignedOrEnvelopedData(Stream, ICertificateFinder, Boolean)	Loads a CMS/PKCS #7 signed or enveloped message from a stream. Returns an instance of SignedData for signed message, EnvelopedData for enveloped message, or null for methods and properties. Inherited from PkcsBase.
Save(Stream)	Saves EnvelopedData into a stream.
