332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync outputs the Delegation Signer (DS) resource record (RR), as defined in
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync RFC 3658 and RFC 4509, for the given key(s).
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Use SHA-1 as the digest algorithm (the default is to use
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync both SHA-1 and SHA-256).
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Use SHA-256 as the digest algorithm.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Select the digest algorithm. The value of
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync <code class="option">algorithm</code> must be one of SHA-1 (SHA1),
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync SHA-256 (SHA256), GOST or SHA-384 (SHA384).
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync These values are case insensitive.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<dt><span class="term">-T <em class="replaceable"><code>TTL</code></em></span></dt>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Specifies the TTL of the DS records.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<dt><span class="term">-K <em class="replaceable"><code>directory</code></em></span></dt>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Look for key files (or, in keyset mode,

332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Zone file mode: in place of the keyfile name, the argument is
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync the DNS domain name of a zone master file, which can be read
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync from <code class="option">file</code>. If the zone name is the same as
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync <code class="option">file</code>, then it may be omitted.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync If <code class="option">file</code> is set to <code class="literal">"-"</code>, then
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync the zone data is read from the standard input. This makes it
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync possible to use the output of the <span><strong class="command">dig</strong></span>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync command as input, as in:

332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Include ZSK's when generating DS records. Without this option,
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync only keys which have the KSK flag set will be converted to DS
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync records and printed. Useful only in zone file mode.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<dt><span class="term">-l <em class="replaceable"><code>domain</code></em></span></dt>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Generate a DLV set instead of a DS set. The specified
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync <code class="option">domain</code> is appended to the name for each
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync record in the set.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync The DNSSEC Lookaside Validation (DLV) RR is described
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync in RFC 4431.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Keyset mode: in place of the keyfile name, the argument is
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync the DNS domain name of a keyset file.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Specifies the DNS class (default is IN). Useful only
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync in keyset or zone file mode.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync Sets the debugging level.
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync To build the SHA-256 DS RR from the

332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync keyfile name, the following command would be issued:
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<p><strong class="userinput"><code>dnssec-dsfromkey -2 Kexample.com.+003+26160</code></strong>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync The command would print something like:
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync<p><strong class="userinput"><code>example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94</code></strong>
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync The keyfile can be designed by the key identification
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync <code class="filename">Knnnn.+aaa+iiiii</code> or the full file name
332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync <code class="filename">Knnnn.+aaa+iiiii.key</code> as generated by

332aaa1da374e694e37fdfe0a00bbe040e670453vboxsync The keyset file name is built from the <code class="option">directory</code>,
