b15d6bddeb80c985f42986dba362c2aaf8803462Mark Andrews outputs the Delegation Signer (DS) resource record (RR), as defined in
47012ae6dbf18a2503d7b33c1c9583dc38625cb7Mark Andrews 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<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Select the digest algorithm. The value of
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">algorithm</code> must be one of SHA-1 (SHA1) or
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein SHA-256 (SHA256). These values are case insensitive.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Look for key files (or, in keyset mode,

727f5b8846457a33d06f515a10a7e1aa849ddf18Andreas Gustafsson 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
f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce <code class="option">file</code>, then it may be omitted.
f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce 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.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Generate a DLV set instead of a DS set. The specified
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <code class="option">domain</code> is appended to the name for each
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein record in the set.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Keyset mode: in place of the keyfile name, the argument is

f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce Specifies the DNS class (default is IN). Useful only
f293a69bcd1c1dd7bdac8f4102fc2398b9e475c8Eric Luce in keyset or zone file mode.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The keyfile can be designed by the key identification
