DNSSEC-DSFROMKEY(8)                  BIND9                 DNSSEC-DSFROMKEY(8)

NAME
       dnssec-dsfromkey - DNSSEC DS RR generation tool
SYNOPSIS
       dnssec-dsfromkey [-v level] [-1] [-2] [-a alg] [-C] [-l domain]
                        [-T TTL] {keyfile}
       dnssec-dsfromkey {-s} [-1] [-2] [-a alg] [-K directory] [-l domain]
                        [-s] [-c class] [-T TTL] [-f file] [-A] [-v level]
                        {dnsname}
       dnssec-dsfromkey [-h] [-V]
DESCRIPTION
       dnssec-dsfromkey outputs the Delegation Signer (DS) resource record
       (RR), as defined in RFC 3658 and RFC 4509, for the given key(s).
OPTIONS
       -1
           Use SHA-1 as the digest algorithm (the default is to use both SHA-1
           and SHA-256).
       -2
           Use SHA-256 as the digest algorithm.
       -a algorithm
           Select the digest algorithm. The value of algorithm must be one of
           SHA-1 (SHA1), SHA-256 (SHA256), GOST or SHA-384 (SHA384). These
           values are case insensitive.
       -C
           Generate CDS records rather than DS records. This is mutually
           exclusive with generating lookaside records.
       -T TTL
           Specifies the TTL of the DS records.
       -K directory
           Look for key files (or, in keyset mode, keyset- files) in
           directory.
       -f file
           Zone file mode: in place of the keyfile name, the argument is the
           DNS domain name of a zone master file, which can be read from file.
           If the zone name is the same as file, then it may be omitted.
           If file is set to "-", then the zone data is read from the standard
           input. This makes it possible to use the output of the dig command
           as input, as in:
           dig dnskey example.com | dnssec-dsfromkey -f - example.com
       -A
           Include ZSKs when generating DS records. Without this option, only
           keys which have the KSK flag set will be converted to DS records
           and printed. Useful only in zone file mode.
       -l domain
           Generate a DLV set instead of a DS set. The specified domain is
           appended to the name for each record in the set. The DNSSEC
           Lookaside Validation (DLV) RR is described in RFC 4431. This is
           mutually exclusive with generating CDS records.
       -s
           Keyset mode: in place of the keyfile name, the argument is the DNS
           domain name of a keyset file.
       -c class
           Specifies the DNS class (default is IN). Useful only in keyset or
           zone file mode.
       -v level
           Sets the debugging level.
       -h
           Prints usage information.
       -V
           Prints version information.
EXAMPLE
       To build the SHA-256 DS RR from the Kexample.com.+003+26160 keyfile
       name, the following command would be issued:
       dnssec-dsfromkey -2 Kexample.com.+003+26160
       The command would print something like:
       example.com. IN DS 26160 5 2
       3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94
FILES
       The keyfile can be designed by the key identification Knnnn.+aaa+iiiii
       or the full file name Knnnn.+aaa+iiiii.key as generated by
       dnssec-keygen(8).
       The keyset file name is built from the directory, the string keyset-
       and the dnsname.
CAVEAT
       A keyfile error can give a "file not found" even if the file exists.
