That seems a bit dramatic to this author :) We can't stuff PDF prefixes into this, there are a lot less bytes for an attacker to play with. > Please also refrain from using MUST- SHOULD+ and SHOULD-. For this SHA1 case or in general? I'd say we could update the DNSSEC Signing entry from MUST- to SHOULD NOT but I would leave SHA1 for DNSSEC validation at MUST-. There is a need to move people away from SHA1, but I don't think this specific attack changing anything with respect to DNSSEC. Paul
