 This is a collection of DNSSEC tools written in Java.  They are intended to be an addition or replacement for the DNSSEC tools that are part of BIND 9.
 
-These tools depend upon DNSjava (http://www.xbill.org/dnsjava), the Jakarta Commons CLI and Logging libraries (https://commons.apache.org/proper/commons-cli), and Sun's Java Cryptography extensions.  A copy of each of these libraries is included in the distribution.  Currently, these tools use a custom version of the DNSjava library with minor modifications, which is provided.
