Remarks

The LoadXmlKeyInfo method deserializes a <KeyInfo> element into a KeyInfo object. The <KeyInfo> XML element is used to specify either a security token type or a specific security token within a SOAP message. So, <KeyInfo> elements are a part of SOAP messages with WS-Security SOAP headers.

The list of elements that can be children of the <KeyInfo> element is dependent upon what is registered on the computer, with the exception of the <SecurityTokenReference> element. The <SecurityTokenReference> element is explicitly defined in the WS-Security specification, so it is supported. WSE also uses the model for loading <KeyInfo> elements that is defined by the System.Security.Cryptography.Xml.KeyInfo and System.Security.Cryptography.Xml.KeyInfoClause classes. Therefore, it is possible to extend the support for all security token managers by registering a custom KeyInfo clause.

It is also possible to extend the list of supported <KeyInfo> child elements separately for each security token manager. To do so, build and configure a custom security token manager that overrides the LoadTokenFromKeyInfo method to parse <KeyInfo> elements with your custom child elements. WSE calls the LoadTokenFromKeyInfo method for all native and configured security token managers when it receives a SOAP message containing a <KeyInfo> element until it finds one that can parse it. For more details about building a custom security token manager, see How to: Create a Security Token Manager for a Custom Security Token.
