Cms Class
Represents a digital sign created with Cryptographic Message Syntax (CMS) - IETF's standard for cryptographically protected messages. CMS is based on the syntax of PKCS #7, specified in RFC 5652. Please see https://tools.ietf.org/html/rfc5652 for more information.

Syntax
public class Cms : DigitalSignature

The Cms type exposes the following members.

Properties
  NameDescription
Public propertyCertificateRawData
Gets the certificate raw data.
(Inherited from DigitalSignature.)
Public propertyCertificates
Gets the collection of certificates.
Public propertyCertificateSubject
Gets the subject distinguished name from a certificate.
(Inherited from DigitalSignature.)
Public propertyComments
Gets the signing purpose comment.
(Inherited from DigitalSignature.)
Public propertyCount
Gets the number of metadata properties.
(Inherited from MetadataPackage.)
Public propertyDigestAlgorithms
Gets the array of message-digest algorithm identifiers. There may be any number of elements in the collection, including zero.
Public propertyEncapsulatedContent
Gets the signed content, consisting of a content type identifier and the content itself.
Public propertyIsValid
Gets a value indicating whether the signature is valid.
(Inherited from DigitalSignature.)
Public propertyItem
Gets the MetadataProperty with the specified name.
(Inherited from MetadataPackage.)
Public propertyKeys
Gets a collection of the metadata property names.
(Inherited from MetadataPackage.)
Public propertyKnowPropertyDescriptors Obsolete.
Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
(Inherited from MetadataPackage.)
Public propertyMetadataType
Gets the metadata type.
(Inherited from MetadataPackage.)
Public propertyPropertyDescriptors
Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
(Inherited from MetadataPackage.)
Public propertySigners
Gets the collection of per-signer information packages.
Public propertySignTime
Gets the time at which the signer (purportedly) performed the signing process.
(Overrides DigitalSignatureSignTime.)
Methods
  NameDescription
Public methodAddProperties
Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
Public methodContains
Determines whether the package contains a metadata property with the specified name.
(Inherited from MetadataPackage.)
Public methodEquals (Inherited from Object.)
Protected methodFinalize (Inherited from Object.)
Public methodFindProperties
Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
Public methodGetEnumerator
Returns an enumerator that iterates through the collection.
(Inherited from MetadataPackage.)
Public methodGetHashCode (Inherited from Object.)
Public methodGetType (Inherited from Object.)
Protected methodMemberwiseClone (Inherited from Object.)
Public methodRemoveProperties
Removes metadata properties satisfying the specified predicate.
(Inherited from MetadataPackage.)
Public methodSanitize
Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
Public methodSetProperties
Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties(FuncMetadataProperty, Boolean, PropertyValue) and UpdateProperties(FuncMetadataProperty, Boolean, PropertyValue). If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.
(Inherited from MetadataPackage.)
Public methodToString (Inherited from Object.)
Public methodUpdateProperties
Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
(Inherited from MetadataPackage.)
