+
+ <p><span class="command"><strong>dnssec-keyfromlabel</strong></span>
+ generates a key pair of files that referencing a key object stored
+ in a cryptographic hardware service module (HSM). The private key
+ file can be used for DNSSEC signing of zone data as if it were a
+ conventional signing key created by <span class="command"><strong>dnssec-keygen</strong></span>,
+ but the key material is stored within the HSM, and the actual signing
+ takes place there.
+ </p>
+ <p>
+ The <code class="option">name</code> of the key is specified on the command
+ line. This must match the name of the zone for which the key is
+ being generated.
+ </p>
+ </div>
+
+ <div class="refsection">
+<a name="id-1.8"></a><h2>OPTIONS</h2>
+
+
+ <div class="variablelist"><dl class="variablelist">
+<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
+<dd>
+ <p>
+ Selects the cryptographic algorithm. The value of
+ <code class="option">algorithm</code> must be one of RSAMD5, RSASHA1,
+ DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512, ECCGOST,
+ ECDSAP256SHA256, ECDSAP384SHA384, ED25519 or ED448.
+ These values are case insensitive.
+ </p>
+ <p>
+ If no algorithm is specified, then RSASHA1 will be used by
+ default, unless the <code class="option">-3</code> option is specified,
+ in which case NSEC3RSASHA1 will be used instead. (If
+ <code class="option">-3</code> is used and an algorithm is specified,
+ that algorithm will be checked for compatibility with NSEC3.)
+ </p>
+ <p>
+ Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
+ algorithm, and DSA is recommended.
+ </p>
+ <p>
+ Note 2: DH automatically sets the -k flag.
+ </p>
+ </dd>
+<dt><span class="term">-3</span></dt>
+<dd>
+ <p>
+ Use an NSEC3-capable algorithm to generate a DNSSEC key.
+ If this option is used and no algorithm is explicitly
+ set on the command line, NSEC3RSASHA1 will be used by
+ default.
+ </p>
+ </dd>
+<dt><span class="term">-E <em class="replaceable"><code>engine</code></em></span></dt>
+<dd>
+ <p>
+ Specifies the cryptographic hardware to use.
+ </p>
+ <p>
+ When BIND is built with OpenSSL PKCS#11 support, this defaults
+ to the string "pkcs11", which identifies an OpenSSL engine
+ that can drive a cryptographic accelerator or hardware service
+ module. When BIND is built with native PKCS#11 cryptography
+ (--enable-native-pkcs11), it defaults to the path of the PKCS#11
+ provider library specified via "--with-pkcs11".
+ </p>
+ </dd>
+<dt><span class="term">-l <em class="replaceable"><code>label</code></em></span></dt>
+<dd>
+ <p>
+ Specifies the label for a key pair in the crypto hardware.
+ </p>
+ <p>
+ When <acronym class="acronym">BIND</acronym> 9 is built with OpenSSL-based
+ PKCS#11 support, the label is an arbitrary string that
+ identifies a particular key. It may be preceded by an
+ optional OpenSSL engine name, followed by a colon, as in
+ "pkcs11:<em class="replaceable"><code>keylabel</code></em>".
+ </p>
+ <p>
+ When <acronym class="acronym">BIND</acronym> 9 is built with native PKCS#11
+ support, the label is a PKCS#11 URI string in the format
+ "pkcs11:<code class="option">keyword</code>=<em class="replaceable"><code>value</code></em>[<span class="optional">;<code class="option">keyword</code>=<em class="replaceable"><code>value</code></em>;...</span>]"
+ Keywords include "token", which identifies the HSM; "object", which
+ identifies the key; and "pin-source", which identifies a file from
+ which the HSM's PIN code can be obtained. The label will be
+ stored in the on-disk "private" file.
+ </p>
+ <p>
+ If the label contains a
+ <code class="option">pin-source</code> field, tools using the generated
+ key files will be able to use the HSM for signing and other
+ operations without any need for an operator to manually enter
+ a PIN. Note: Making the HSM's PIN accessible in this manner
+ may reduce the security advantage of using an HSM; be sure
+ this is what you want to do before making use of this feature.
+ </p>
+ </dd>
+<dt><span class="term">-n <em class="replaceable"><code>nametype</code></em></span></dt>
+<dd>
+ <p>
+ Specifies the owner type of the key. The value of
+ <code class="option">nametype</code> must either be ZONE (for a DNSSEC
+ zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
+ a host (KEY)),
+ USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
+ These values are case insensitive.
+ </p>
+ </dd>
+<dt><span class="term">-C</span></dt>
+<dd>
+ <p>
+ Compatibility mode: generates an old-style key, without
+ any metadata. By default, <span class="command"><strong>dnssec-keyfromlabel</strong></span>
+ will include the key's creation date in the metadata stored
+ with the private key, and other dates may be set there as well
+ (publication date, activation date, etc). Keys that include
+ this data may be incompatible with older versions of BIND; the
+ <code class="option">-C</code> option suppresses them.
+ </p>
+ </dd>
+<dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
+<dd>
+ <p>

+ </p>
+ </dd>
+<dt><span class="term">-f <em class="replaceable"><code>flag</code></em></span></dt>
+<dd>
+ <p>
+ Set the specified flag in the flag field of the KEY/DNSKEY record.
+ The only recognized flags are KSK (Key Signing Key) and REVOKE.
+ </p>
+ </dd>
+<dt><span class="term">-G</span></dt>

+ Generate KEY records rather than DNSKEY records.
+ </p>
+ </dd>
+<dt><span class="term">-L <em class="replaceable"><code>ttl</code></em></span></dt>
+<dd>
+ <p>
+ Sets the default TTL to use for this key when it is converted
+ into a DNSKEY RR. If the key is imported into a zone,
+ this is the TTL that will be used for it, unless there was
+ already a DNSKEY RRset in place, in which case the existing TTL
+ would take precedence. Setting the default TTL to
+ <code class="literal">0</code> or <code class="literal">none</code> removes it.
+ </p>
+ </dd>
+<dt><span class="term">-p <em class="replaceable"><code>protocol</code></em></span></dt>
+<dd>
+ <p>
+ Sets the protocol value for the key. The protocol
+ is a number between 0 and 255. The default is 3 (DNSSEC).
+ Other possible values for this argument are listed in
+ RFC 2535 and its successors.
+ </p>
+ </dd>
+<dt><span class="term">-S <em class="replaceable"><code>key</code></em></span></dt>
+<dd>
+ <p>
+ Generate a key as an explicit successor to an existing key.
+ The name, algorithm, size, and type of the key will be set
+ to match the predecessor. The activation date of the new
+ key will be set to the inactivation date of the existing
+ one. The publication date will be set to the activation
+ date minus the prepublication interval, which defaults to
+ 30 days.
+ </p>
+ </dd>
+<dt><span class="term">-t <em class="replaceable"><code>type</code></em></span></dt>
+<dd>
+ <p>
+ Indicates the use of the key. <code class="option">type</code> must be
+ one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
+ is AUTHCONF. AUTH refers to the ability to authenticate
+ data, and CONF the ability to encrypt data.
+ </p>
+ </dd>
+<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
+<dd>

+<dd>
+ <p>
+ Allows DNSSEC key files to be generated even if the key ID
+ would collide with that of an existing key, in the event of

+ with either of the keys involved.)

+ Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
+ If the argument begins with a '+' or '-', it is interpreted as
+ an offset from the present time. For convenience, if such an offset
+ is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
+ then the offset is computed in years (defined as 365 24-hour days,
+ ignoring leap years), months (defined as 30 24-hour days), weeks,
+ days, hours, or minutes, respectively. Without a suffix, the offset
+ is computed in seconds. To explicitly prevent a date from being
+ set, use 'none' or 'never'.

+
+ <div class="variablelist"><dl class="variablelist">

+ </dd>
+<dt><span class="term">-A <em class="replaceable"><code>date/offset</code></em></span></dt>
+<dd>

+ in the zone and will be used to sign it.
+ </p>
+ </dd>
+<dt><span class="term">-I <em class="replaceable"><code>date/offset</code></em></span></dt>

+<dd>
+ <p>
+ Sets the prepublication interval for a key. If set, then
+ the publication and activation dates must be separated by at least

+ to this much time before the activation date; conversely, if
+ the publication date is specified but activation date isn't,
+ then activation will be set to this much time after publication.

+ <p>
+ If the key is being created as an explicit successor to another
