Replace :manpage: with :iscman: to generate internal hyperlinks. That
way reader can use links even when offline, and jumps to man pages
for the same version.
Formerly HTML version of man pages did not have links in See Also
section because :manpage: role in Sphinx can generate only external
hyperlinks - and we do not have that enabled.
Enabling the Sphinx :manpage: linking could reliably create hyperlinks
only to external URLs, but that would take users to another version
of docs.

+ hand-edit to revert change for mmencode reference which is
not provided in our source tree.

Description
|
|
~~~~~~~~~~~
|
|
|
|
The :program:`dnssec-dsfromkey` command outputs DS (Delegation Signer) resource records
|
|
(RRs), or CDS (Child DS) RRs with the :option:`-C` option.
|
|
|
|
By default, only KSKs are converted (keys with flags = 257). The
|
|
:option:`-A` option includes ZSKs (flags = 256). Revoked keys are never
|
|
included.
|
|
|
|
The input keys can be specified in a number of ways:
|
|
|
|
By default, :program:`dnssec-dsfromkey` reads a key file named in the format
|
|
``Knnnn.+aaa+iiiii.key``, as generated by :iscman:`dnssec-keygen`.
|
|
|
|
With the :option:`-f file <-f>` option, :program:`dnssec-dsfromkey` reads keys from a zone
|
|
file or partial zone file (which can contain just the DNSKEY records).
|
|
|
|
With the :option:`-s` option, :program:`dnssec-dsfromkey` reads a ``keyset-`` file,
|
|
as generated by :iscman:`dnssec-keygen` :option:`-C`.
|
|
|
|
Options
|
|
~~~~~~~
|
|
|
|
.. option:: -1
|
|
|
|
This option is an abbreviation for :option:`-a SHA1 <-a>`.
|
|
|
|
.. option:: -2
|
|
|
|
This option is an abbreviation for :option:`-a SHA-256 <-a>`.
|
|
|
|
.. option:: -a algorithm
|
|
|
|
This option specifies a digest algorithm to use when converting DNSKEY records to
|
|
DS records. This option can be repeated, so that multiple DS records
|
|
are created for each DNSKEY record.
|
|
|
|
The algorithm must be one of SHA-1, SHA-256, or SHA-384. These values
|
|
are case-insensitive, and the hyphen may be omitted. If no algorithm
|
|
is specified, the default is SHA-256.
|
|
|
|
.. option:: -A
|
|
|
|
This option indicates that ZSKs are to be included when generating DS records. Without this option, only
|
|
keys which have the KSK flag set are converted to DS records and
|
|
printed. This option is only useful in :option:`-f` zone file mode.
|
|
|
|
.. option:: -c class
|
|
|
|
This option specifies the DNS class; the default is IN. This option is only useful in :option:`-s` keyset
|
|
or :option:`-f` zone file mode.
|
|
|
|
.. option:: -C
|
|
|
|
This option generates CDS records rather than DS records.
|
|
|
|
.. option:: -f file
|
|
|
|
This option sets zone file mode, in which the final dnsname argument of :program:`dnssec-dsfromkey` is the
|
|
DNS domain name of a zone whose master file can be read from
|
|
``file``. If the zone name is the same as ``file``, then it may be
|
|
omitted.
|
|
|
|
If ``file`` is ``-``, then the zone data is read from the standard
|
|
input. This makes it possible to use the output of the :iscman:`dig`
|
|
command as input, as in:
|
|
|
|
``dig dnskey example.com | dnssec-dsfromkey -f - example.com``
|
|
|
|
.. option:: -h
|
|
|
|
This option prints usage information.
|
|
|
|
.. option:: -K directory
|
|
|
|
This option tells BIND 9 to look for key files or ``keyset-`` files in ``directory``.
|
|
|
|
.. option:: -s
|
|
|
|
This option enables keyset mode, in which the final dnsname argument from :program:`dnssec-dsfromkey` is the DNS
|
|
domain name used to locate a ``keyset-`` file.
|
|
|
|
.. option:: -T TTL
|
|
|
|
This option specifies the TTL of the DS records. By default the TTL is omitted.
|
|
|
|
.. option:: -v level
|
|
|
|
This option sets the debugging level.
|
|
|
|
.. option:: -V
|
|
|
|
This option prints version information.
|

Example
|
|
~~~~~~~
|
|
|
|
To build the SHA-256 DS RR from the ``Kexample.com.+003+26160`` keyfile,
|
|
issue the following command:
|
|
|
|
``dnssec-dsfromkey -2 Kexample.com.+003+26160``
|
|
|
|
The command returns something similar to:
|
|
|
|
``example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0C5EA0B94``
|
|
|
|
Files
|
|
~~~~~
|
|
|
|
The keyfile can be designated by the key identification
|
|
``Knnnn.+aaa+iiiii`` or the full file name ``Knnnn.+aaa+iiiii.key``, as
|
|
generated by :iscman:`dnssec-keygen`.
|
|
|
|
The keyset file name is built from the ``directory``, the string
|
|
``keyset-``, and the ``dnsname``.
|
|
|
|
Caveat
|
|
~~~~~~
|
|
|
|
A keyfile error may return "file not found," even if the file exists.
