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
