NAME

       ldns-key2ds - transform a DNSKEY RR to a DS RR

SYNOPSIS

       ldns-key2ds file

DESCRIPTION

       ldns-key2ds  is  used  to  transform a public DNSKEY RR to a DS RR.  When run it will read
       file with a DNSKEY RR in it and it will create a .ds file with the DS RR in it.

       It prints out the basename for this file (K<name>+<alg>+<id>).

       By default it takes a pick of algorithm similar to the key algorithm,  SHA1  for  RSASHA1,
       and so on.

OPTIONS

       -f     Ignore SEP flag (i.e. make DS records for any key)

       -n     Write the result DS Resource Record to stdout instead of a file

       -1     Use SHA1 as the hash function.

       -2     Use SHA256 as the hash function

       -g     Use GOST as the hash function

       -4     Use SHA384 as the hash function
