5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync generates keys for DNSSEC (Secure DNS), as defined in RFC 2535
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync and RFC 4034. It can also generate keys for use with
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync (Transaction Key) as defined in RFC 2930.
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync The <code class="option">name</code> of the key is specified on the command
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync line. For DNSSEC keys, this must match the name of the zone for
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync which the key is being generated.
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync Selects the cryptographic algorithm. For DNSSEC keys, the value
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync of <code class="option">algorithm</code> must be one of RSAMD5, RSASHA1,
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256 or RSASHA512.
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync be DH (Diffie Hellman), HMAC-MD5, HMAC-SHA1, HMAC-SHA224,
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512. These values are
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync case insensitive.
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync If no algorithm is specified, then RSASHA1 will be used by
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync default, unless the <code class="option">-3</code> option is specified,
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync in which case NSEC3RSASHA1 will be used instead. (If
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync <code class="option">-3</code> is used and an algorithm is specified,
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync that algorithm will be checked for compatibility with NSEC3.)
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync algorithm, and DSA is recommended. For TSIG, HMAC-MD5 is
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync Note 2: DH, HMAC-MD5, and HMAC-SHA1 through HMAC-SHA512
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync automatically set the -T KEY option.

caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync Specifies the number of bits in the key. The choice of key
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync size depends on the algorithm used. RSA keys must be
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync between 512 and 2048 bits. Diffie Hellman keys must be between
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync 128 and 4096 bits. DSA keys must be between 512 and 1024
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync bits and an exact multiple of 64. HMAC keys must be
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync between 1 and 512 bits.
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync The key size does not need to be specified if using a default
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync algorithm. The default key size is 1024 bits for zone signing
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync keys (ZSK's) and 2048 bits for key signing keys (KSK's,
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync generated with <code class="option">-f KSK</code>). However, if an
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync algorithm is explicitly specified with the <code class="option">-a</code>,
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync then there is no default key size, and the <code class="option">-b</code>
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync must be used.
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync<dt><span class="term">-n <em class="replaceable"><code>nametype</code></em></span></dt>
caf62c8b1a43cb2321f2b9d4e31588e643b89731vboxsync Specifies the owner type of the key. The value of
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync <code class="option">nametype</code> must either be ZONE (for a DNSSEC
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync a host (KEY)),
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync These values are case insensitive. Defaults to ZONE for DNSKEY
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync generation.
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync Use an NSEC3-capable algorithm to generate a DNSSEC key.
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync If this option is used and no algorithm is explicitly
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync set on the command line, NSEC3RSASHA1 will be used by
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync default. Note that RSASHA256 and RSASHA512 algorithms
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync are NSEC3-capable.
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync Compatibility mode: generates an old-style key, without
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync any metadata. By default, <span><strong class="command">dnssec-keygen</strong></span>
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync will include the key's creation date in the metadata stored
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync with the private key, and other dates may be set there as well
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync (publication date, activation date, etc). Keys that include
c558b8f73de73ad85632b07ca3fb1a5b2a808ad9vboxsync this data may be incompatible with older versions of BIND; the
5ad4f48b2792391dd4a1aea599953037dfc8f456vboxsync <code class="option">-C</code> option suppresses them.

9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync Specifies the resource record type to use for the key.
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync <code class="option">rrtype</code> must be either DNSKEY or KEY. The
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync default is DNSKEY when using a DNSSEC algorithm, but it can be
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync overridden to KEY for use with SIG(0).

9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync Indicates the use of the key. <code class="option">type</code> must be
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync is AUTHCONF. AUTH refers to the ability to authenticate
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync data, and CONF the ability to encrypt data.

9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync If the argument begins with a '+' or '-', it is interpreted as
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync an offset from the present time. For convenience, if such an offset
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync then the offset is computed in years (defined as 365 24-hour days,
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync ignoring leap years), months (defined as 30 24-hour days), weeks,
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync days, hours, or minutes, respectively. Without a suffix, the offset
9d6ab2e4cb34fe72107aec65496ee8c880fd95advboxsync is computed in seconds.
