Cms

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.

public class Cms : DigitalSignature

Properties

Name Description
CertificateRawData { get; } Gets the certificate raw data.
Certificates { get; } Gets the collection of certificates.
CertificateSubject { get; } Gets the subject distinguished name from a certificate.
Comments { get; } Gets the signing purpose comment.
Count { get; } Gets the number of metadata properties.
DigestAlgorithms { get; } Gets the array of message-digest algorithm identifiers. There may be any number of elements in the collection, including zero.
EncapsulatedContent { get; } Gets the signed content, consisting of a content type identifier and the content itself.
virtual IsValid { get; } Gets a value indicating whether the signature is valid.
Item { get; } Gets the MetadataProperty with the specified name.
Keys { get; } Gets a collection of the metadata property names.
MetadataType { get; } Gets the metadata type.
PropertyDescriptors { get; } Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
Signers { get; } Gets the collection of per-signer information packages.
override SignTime { get; } Gets the time at which the signer (purportedly) performed the signing process.

Methods

Name Description
virtual AddProperties(Func<MetadataProperty, bool>, PropertyValue) Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
Contains(string) Determines whether the package contains a metadata property with the specified name.
virtual FindProperties(Func<MetadataProperty, bool>) Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
GetEnumerator() Returns an enumerator that iterates through the collection.
virtual RemoveProperties(Func<MetadataProperty, bool>) Removes metadata properties satisfying the specified predicate.
virtual Sanitize() Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
virtual SetProperties(Func<MetadataProperty, bool>, PropertyValue) 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 and UpdateProperties. 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.
virtual UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
