Sebb commented on HTTPCLIENT-1316:
----------------------------------
I've looked further at the patch, and it uses InetAddress.getByName() to parse
the address if it looks like an IPv6 address.
It then reformats the output of Inet6Address.getHostAddress().
That should be sufficient for purely comparison purposes - there's no need to
canonicalize the string format as per RFC5952.
Obviously, care needs to be taken that the code does not try to do any DNS
lookups...

> Key: HTTPCLIENT-1316
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1316
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpConn
> Affects Versions: 4.2.3
> Reporter: James Livingston
> Fix For: Future
>
>
> org.apache.http.conn.ssl.AbstractVerifier.verify() does not correctly handle
> host name verification when IPv6 addresses are used, as it simply does a
> string equality check when doWildcard is false.
> http://tools.ietf.org/html/rfc5952#section-3.2.5 specifically mentions X.509
> certificates as an example when textual comparison of IPv6 addresses is not
> correct. Examples of incorrect behaviour are with:
> * leading zeroes
> * zero compression
> * case insensitivity
> For example if you have a SSL certificate for the IP address
> 2001:0db8:aaaa:bbbb:cccc:0:0:0001, the alternative representation of
> 2001:db8:AAAA:bbbb:cccc::1 should be accepted as a match.
