63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi outputs the Delegation Signer (DS) resource record (RR), as defined in
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi RFC 3658 and RFC 4509, for the given key(s).
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Use SHA-1 as the digest algorithm (the default is to use
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi both SHA-1 and SHA-256).
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Use SHA-256 as the digest algorithm.

63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Select the digest algorithm. The value of
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi <code class="option">algorithm</code> must be one of SHA-1 (SHA1) or
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi SHA-256 (SHA256). These values are case insensitive.

63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Look for key files (or, in keyset mode,
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi <code class="filename">keyset-</code> files) in

63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Zone file mode: in place of the keyfile name, the argument is
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi the DNS domain name of a zone master file, which can be read
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi from <code class="option">file</code>. If the zone name is the same as
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi <code class="option">file</code>, then it may be omitted.
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Include ZSK's when generating DS records. Without this option,
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi only keys which have the KSK flag set will be converted to DS
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi records and printed. Useful only in zone file mode.

63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi Generate a DLV set instead of a DS set. The specified
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi <code class="option">domain</code> is appended to the name for each
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi record in the set.
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi The DNSSEC Lookaside Validation (DLV) RR is described
63ee0c9f26b85deae17137a3965738153e0b2d20Gabor Melkvi in RFC 4431.
