Security expert Dan Kaminsky has announced Phreebird, an easy-to-use tool set for creating digital signatures based on the DNS Security Extensions (DNSSEC) The tool reportedly allows ISPs to sign all their customers’ domains in one go. The DNSSEC technology encrypts DNS responses via crypto keys which allow recipients to verify the authenticity of a message and a sender’s status as a trusted link in the chain. The tool isn’t ready for production use, says Kaminsky.”]
