When will NSEC 3 support be available in dnssec-tools?
We've been waiting for the base release of bind to incorperate nsec3 support. Because that code is generally available now we'll try and get our 1.5 release to contain support for it and work on getting that out the door asap.
I should point out that our validation library (see 1.4.2.rc1 or higher) contains support for NSEC3, but it is preliminary and not extensively tested yet.
It's now supported in the 1.5 release.
