The ß-β near-collision is not a problem because ß is normalized to ss. I've been joking that the <http://www.buße.de> (which once was about buses, not penance) was one of the first IDNs. This highlights a significant problem with IDNA implementations: IDNA only makes sense as some sort of opaque hashing mechanism to get a resource from DNS. The protocol does not actually support going backwards, from IDNA-encoded name to the original Unicode string. The Mozilla implementation is totally broken in this regard. _______________________________________________ dev-security mailing list [email protected] https://lists.mozilla.org/listinfo/dev-security
