Represents CMS per-signer information.
public class CmsSigner : CustomPackage
Properties
Name | Description |
---|---|
Count { get; } | Gets the number of metadata properties. |
DigestAlgorithm { get; } | Gets the message digest algorithm, and any associated parameters, used by the signer. |
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. |
SignatureAlgorithm { get; } | Gets the signature algorithm, and any associated parameters, used by the signer to generate the digital signature. |
SignatureValue { get; } | Gets the result of digital signature generation, using the message digest and the signer’s private key. |
SignedAttributes { get; } | Gets the collection of attributes that are signed. |
SignerIdentifier { get; } | Gets the signer’s certificate (and thereby the signer’s public key) raw data. |
SigningTime { get; } | Gets the time at which the signer (purportedly) performed the signing process. |
UnsignedAttributes { get; } | Gets the collection of attributes that are not signed. |
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. |
