CmsSigner.SignedAttributes Property

The SignedAttributes property retrieves the CryptographicAttributeCollection collection of signed attributes to be associated with the resulting SignerInfo content. Signed attributes are signed along with the specified content.

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

public CryptographicAttributeObjectCollection SignedAttributes { get; }
/** @property */
public CryptographicAttributeObjectCollection get_SignedAttributes ()

public function get SignedAttributes () : CryptographicAttributeObjectCollection

Not applicable.

Property Value

A CryptographicAttributeCollection collection that represents the signed attributes. If there are no signed attributes, the property is an empty collection.

An example of a signed attribute that might be included in the CryptographicAttributeCollection collection retrieved by the SignedAttributes property is the Pkcs9SigningTime signing time attribute.

A Pkcs9ContentType object and a Pkcs9MessageDigest object will be automatically generated and placed in the SignerInfo.SignedAttributes property for the corresponding signer whenever the SignedAttributes property is not empty.
