<p class="MsoNormal">Hello,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm looking for DNSSEC validation tool/library (ideally PHP/Python/shell) which can perform validation on a DNSKEY record using trust anchor provided as DS record.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">The use case is Registry receives request for DS delegation data update, then it uses this data and the DNSKEY RRSet from the authoritative servers to validate the DNSKEY RRSIG.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Any recommendations will be much appreciated. Thank you in advance.<o:p></o:p></p>
