a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov outputs the Delegation Signer (DS) resource record (RR), as defined in
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov RFC 3658 and RFC 4509, for the given key(s).
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov Use SHA-1 as the digest algorithm (the default is to use
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov both SHA-1 and SHA-256).
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov Use SHA-256 as the digest algorithm.

a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov Select the digest algorithm. The value of
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov <code class="option">algorithm</code> must be one of SHA-1 (SHA1) or

a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov Sets the debugging level.
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov Keyset mode: in place of the keyfile name, the argument is
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov the DNS domain name of a keyset file. Following options make sense
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov only in this mode.

a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov Specifies the DNS class (default is IN), useful only
a9478106a12424322498e53cf7cd75bd8a4d6004Yuri Pankov in the keyset mode.
