[jbosstools-issues] [JBoss JIRA] (JBIDE-19594) SSL callback: provide meaningful hostname verifier, stop always accepting hostnames

SSL callback: provide meaningful hostname verifier, stop always accepting hostnames ----------------------------------------------------------------------------------- Key: JBIDE-19594 URL: https://issues.jboss.org/browse/JBIDE-19594 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: openshift Affects Versions: 4.3.0.Alpha2 Reporter: Andre Dietisheim Fix For: 4.5.0.AM1 We're currently using an SSL callback that will allow users to get informed and act upon "faulty" certificates (ex. self-signed ones) and mismatches btw. the host we're talking to and the one that is referenced in the ssl certificate: {code:title=com.openshift.client.IHttpClient.ISSLCertificateCallback} public interface ISSLCertificateCallback { public boolean allowCertificate(X509Certificate[] chain); public boolean allowHostname(String hostname, SSLSession session); } {code} The callback that we are using in JBT is presenting a dialog in case the jdk cannot verify the certificate (ex. self signed certificates) and allows the user to accept/deny it. In case the jdk cannot verify the hostname (the host we're talking to is not matching the host that's referenced in the certificate) we're currently always accepting the hostname: {code:title=org.jboss.tools.openshift.express.internal.ui.wizard.connection.SSLCertificateCallback} @Override public boolean allowHostname(String hostname, SSLSession sslSession) { return true; } {code} We should find a meaningfull implementation of such a verification that does not simply always accept it. A first idea would be to present the mismatch to the user and allow it to accept/refute it. This issue came up JBIDE-19581 when there was no callback installed which made the hostname verification fail as in jdk.
