Michael Moser commented on NIFI-5400:
-------------------------------------
Sorry, I thought this was related to the recent discussions on the DEV list
about wildcard SSL certificate restrictions for configurations of the REST API
and UI. I withdraw the comment for this ticket.
> NiFiHostnameVerifier should be replaced
> ---------------------------------------
>
> Key: NIFI-5400
> URL: https://issues.apache.org/jira/browse/NIFI-5400
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.7.0
> Reporter: Andy LoPresto
> Priority: Major
> Labels: certificate, hostname, security, tls
>
> The {{NiFiHostnameVerifier}} does not handle wildcard certificates or complex
> {{SubjectAlternativeNames}}. It should be replaced with a more full-featured
> implementation, like {{OkHostnameVerifier}} from {{okhttp}} or
> {{DefaultHostnameVerifier}} from {{http-client}}. Either of these options
> requires introducing a new Maven dependency to {{nifi-commons}} and requires
> further investigation.
> *Note: * the {{sun.net.www.protocol.httpsDefaultHostnameVerifier}} simply
> returns {{false}} on all inputs and is not a valid solution.
