60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein outputs the Delegation Signer (DS) resource record (RR), as defined in
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein RFC 3658 and RFC 4509, for the given key(s).
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Use SHA-1 as the digest algorithm (the default is to use
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein both SHA-1 and SHA-256).
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Use SHA-256 as the digest algorithm.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Select the digest algorithm. The value of
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">algorithm</code> must be one of SHA-1 (SHA1),
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein SHA-256 (SHA256) or GOST. These values are case insensitive.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Zone file mode: in place of the keyfile name, the argument is
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the DNS domain name of a zone master file, which can be read
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein from <code class="option">file</code>. If the zone name is the same as
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">file</code>, then it may be omitted.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein If <code class="option">file</code> is set to <code class="literal">"-"</code>, then
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the zone data is read from the standard input. This makes it
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein possible to use the output of the <span><strong class="command">dig</strong></span>
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein command as input, as in:

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Include ZSK's when generating DS records. Without this option,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein only keys which have the KSK flag set will be converted to DS
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein records and printed. Useful only in zone file mode.
