dcpAuthHMACTransformation


The Internet of Things: Edge Connect product allows connected users and devices to communicate on a publish-subscribe basis within reserved namespaces. In conjunction with dcp‚ÄčAuth‚ÄčVariable‚ÄčExtractor, this behavior affects how clients can authenticate themselves to edge servers, and which groups within namespaces are authorized to access topics. It transforms a source string value extracted from the client certificate and stored as a variable, then generates a hash value based on the selected algorithm, for use in authenticating the client request.

Note that you can apply this hash transformation, or either of the dcp‚ÄčAuth‚ÄčRegex‚ÄčTransformation or dcp‚ÄčAuth‚ÄčSubstring‚ÄčTransformation behaviors.
