[ http://issues.apache.org/jira/browse/HTTPCLIENT-614?page=comments#action_12456895 ] Ortwin Glück commented on HTTPCLIENT-614: -----------------------------------------
Good point, Julius. Personally I have no experience with SSL on vhosts. But looking at the references document it looks like we should support the "CN+SubjAltNames" and "SubjectAltName" variants. May I mention that the * solution in 613 is wrong: if ( wildcard ) match = host.endsWith( cn.substring( 1 ) ); would result in bar.foo.a.com matching *.a.com but RFC says: E.g., *.a.com matches foo.a.com but not bar.foo.a.com. Making a mistake here opens spoofing possibilities! > allow different strategies when checking CN of x509 cert > -------------------------------------------------------- > > Key: HTTPCLIENT-614 > URL: http://issues.apache.org/jira/browse/HTTPCLIENT-614 > Project: HttpComponents HttpClient > Issue Type: Improvement > Components: HttpClient > Affects Versions: Nightly Builds > Reporter: Julius Davies > Priority: Minor > > We're now doing a decent job for checking the CN of the x509 cert with https: > http://issues.apache.org/jira/browse/HTTPCLIENT-613 > I think the patch for HTTPCLIENT-613 should cover 99.9% of the users out > there.
