b27ce68bae92006e2ad7a9b75602c6385e529c3bAutomatic Updater outputs the Delegation Signer (DS) resource record (RR), as defined in
922312472e2e05ebc64993d465999c5351b83036Automatic Updater RFC 3658 and RFC 4509, for the given key(s).
582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews Use SHA-1 as the digest algorithm (the default is to use
582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews both SHA-1 and SHA-256).
582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews Use SHA-256 as the digest algorithm.

582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews Select the digest algorithm. The value of
582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews <code class="option">algorithm</code> must be one of SHA-1 (SHA1) or
582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews SHA-256 (SHA256). These values are case insensitive.

0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Look for key files (or, in keyset mode,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater <code class="filename">keyset-</code> files) in

0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Zone file mode: in place of the keyfile name, the argument is
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater the DNS domain name of a zone master file, which can be read
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater from <code class="option">file</code>. If the zone name is the same as
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater <code class="option">file</code>, then it may be omitted.
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Include ZSK's when generating DS records. Without this option,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater only keys which have the KSK flag set will be converted to DS
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater records and printed. Useful only in zone file mode.

b272d38cc5d24f64c0647a9afb340c21c4b9aaf7Evan Hunt Generate a DLV set instead of a DS set. The specified
b272d38cc5d24f64c0647a9afb340c21c4b9aaf7Evan Hunt <code class="option">domain</code> is appended to the name for each
b272d38cc5d24f64c0647a9afb340c21c4b9aaf7Evan Hunt record in the set.
582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews Keyset mode: in place of the keyfile name, the argument is
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater the DNS domain name of a keyset file.

0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Specifies the DNS class (default is IN). Useful only
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater in keyset or zone file mode.
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Sets the debugging level.

582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews The command would print something like:

582f8b9a8d170a80ef67475bddb8ad5cf7cd7cadMark Andrews The keyfile can be designed by the key identification
