Another SSHFP record script converter for tinydns

["Antonio Dias" <lists@sys.pro.br>]

Hello, all.

Here is another script to generate SSHFP resource records in tinydns
format. This one is in gawk and will generate records for all keys
found in the host where it run. I wish it be useful for you:

#!/usr/bin/gawk -f
BEGIN {
  hostname=ENVIRON["HOSTNAME"]
  keygen="ssh-keygen -gr " hostname
  while(keygen | getline) {
     if($8) {
        rr=sprintf(":%s:44:\\%03.3o\\%03.3o", hostname, $6, $7)
        for(i=1; i<length($8); i+=2) {
           rr=sprintf("%s\\%03.3o", rr, strtonum("0x" substr($8, i, 2)))
        }
        print "# " $0
        print rr ":::"
     }
  }
}
