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.

f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce Zone file mode: in place of the keyfile name, the argument is
f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce the DNS domain name of a zone master file, which can be read
f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce from <code class="option">file</code>. If the zone name is the same as

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.
