90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont gets keys with the given label from a crypto hardware and builds
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont key files for DNSSEC (Secure DNS), as defined in RFC 2535
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont and RFC 4034.
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater The <code class="option">name</code> of the key is specified on the command
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater line. This must match the name of the zone for which the key is
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater being generated.

90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont Selects the cryptographic algorithm. The value of
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater <code class="option">algorithm</code> must be one of RSAMD5 (RSA),
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA or DH (Diffie Hellman).
731cc132f22dbc9e0ecd7035dce314a61076d31bAutomatic Updater These values are case insensitive.
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater If no algorithm is specified, then RSASHA1 will be used by
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater default, unless the <code class="option">-3</code> option is specified,
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater in which case NSEC3RSASHA1 will be used instead.
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont algorithm, and DSA is recommended.
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont Note 2: DH automatically sets the -k flag.
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater Use an NSEC3-capable algorithm to generate a DNSSEC key.
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater If this option is used and no algorithm is explicitly
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater set on the command line, NSEC3RSASHA1 will be used by

2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater Specifies the label of the key pair in the crypto hardware.
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater The label may be preceded by an optional OpenSSL engine name,
2a6d4c9948b3f4f31311bd799d114585a30419a9Automatic Updater separated by a colon, as in "pkcs11:keylabel".

90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont Specifies the owner type of the key. The value of
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont <code class="option">nametype</code> must either be ZONE (for a DNSSEC
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont a host (KEY)),
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).

c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater any metadata. By default, <span><strong class="command">dnssec-keyfromlabel</strong></span>
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater will include the key's creation date in the metadata stored
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater with the private key, and other dates may be set there as well
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater (publication date, activation date, etc). Keys that include
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater this data may be incompatible with older versions of BIND; the
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater <code class="option">-C</code> option suppresses them.

c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater The only recognized flags are KSK (Key Signing Key) and REVOKE.

f8e3e03cacd16ffb923a9603fca23a9e1a1fee07Automatic Updater option is incompatible with -P and -A.

c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater Sets the protocol value for the key. The protocol
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont is a number between 0 and 255. The default is 3 (DNSSEC).

90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont Indicates the use of the key. <code class="option">type</code> must be
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont is AUTHCONF. AUTH refers to the ability to authenticate
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont data, and CONF the ability to encrypt data.
