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_auth_variable_extractor, 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 extracts a substring, for use in authenticating the client request.

Note that you can apply this substring transformation, or either of the dcp_auth_hmactransformation or dcp_auth_regex_transformation behaviors.

Option Type Description Requires

Option	Type	Description	Requires
`substring_start`	string	The zero-based index offset of the first character to extract. If the index is out of bound from the string's length, authentication may fail.		{"displayType":"string","tag":"input","type":"text"}
`substring_end`	string	The zero-based index offset of the last character to extract, where `-1` selects the remainder of the string. If the index is out of bound from the string's length, authentication may fail.		{"displayType":"string","tag":"input","type":"text"}
