PackageDigitalSignatureManager.HashAlgorithm Property
Gets or sets the URI identifier for the HashAlgorithm instance used to create and verify signatures.
Namespace: System.IO.Packaging
Assembly: WindowsBase (in WindowsBase.dll)
XMLNS for XAML: Not mapped to an xmlns.
<object HashAlgorithm="string" .../>
Property Value
Type: System.StringThe SignedXml URI identifier for the HashAlgorithm instance used to create and verify signatures.
| Exception | Condition |
|---|---|
| ArgumentNullException | The string for the URI to set is null. |
| ArgumentException | The string for the URI to set is empty. |
The default hash algorithm identifier for the standard digital signature manager is XmlDsigSHA1Url (SHA1—Secure Hash Algorithm version 1.0).
Unless explicitly set otherwise, this property gets the same value as DefaultHashAlgorithm.
The HashAlgorithm property is typically not changed from its default. This property must be changed only if a signature that uses a different known and accessible HashAlgorithm is encountered. When finished with the signature that uses a different hash algorithm, call DefaultHashAlgorithm to reset the HashAlgorithm property back to default.
