The tools/hipdnskeyparse directory contains a script which converts public key file contents to different DNS zone file formats. To convert to unpatched BIND9 format, run the following:

hipdnskeyparse < /etc/hip/hip_host_rsa_key_pub.pub hostname.domain.org | sed -n -e '/^9BIND */s///p'
      

This outputs a line which can be inserted to a zone file. Similarly, with sed command:

.... | sed -n -e '/^DJBDNS */s///p'
      

a line for Dan Bernstein's tinydns is output. For further information, please refer to hipdnskeyparse and myasn.py.
