5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews<p><span><strong class="command">dnssec-keygen</strong></span>
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews generates keys for DNSSEC (Secure DNS), as defined in RFC 2535
d71e2e0c61df16ff37c9934c371a4a60c08974f7Mark Andrews and RFC 4034. It can also generate keys for use with
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater (Transaction Key) as defined in RFC 2930.
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Selects the cryptographic algorithm. For DNSSEC keys, the value
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater of <code class="option">algorithm</code> must be one of RSAMD5, RSASHA1,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater DSA, NSEC3RSASHA1, or NSEC3DSA. For TSIG/TKEY, the value must
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater be DH (Diffie Hellman), HMAC-MD5, HMAC-SHA1, HMAC-SHA224,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512. These values are
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater case insensitive.
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater If no algorithm is specified, then RSASHA1 will be used by
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater default, unless the <code class="option">-3</code> option is specified,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater in which case NSEC3RSASHA1 will be used instead.
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
731cc132f22dbc9e0ecd7035dce314a61076d31bAutomatic Updater algorithm, and DSA is recommended. For TSIG, HMAC-MD5 is
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Note 2: DH, HMAC-MD5, and HMAC-SHA1 through HMAC-SHA512
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater automatically set the -T KEY option.

5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews Specifies the number of bits in the key. The choice of key
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews size depends on the algorithm used. RSAMD5 / RSASHA1 keys must be
ca67ebfe9eef0b8f04179f7e511a19e0337a5422Automatic Updater between 512 and 2048 bits. Diffie Hellman keys must be between
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews 128 and 4096 bits. DSA keys must be between 512 and 1024
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews bits and an exact multiple of 64. HMAC-MD5 keys must be
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews between 1 and 512 bits.
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater The key size does not need to be specified if using a default
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater algorithm. The default key size is 1024 bits for zone signing
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater keys (ZSK's) and 2048 bits for key signing keys (KSK's,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater generated with <code class="option">-f KSK</code>). However, if an
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater algorithm is explicitly specified with the <code class="option">-a</code>,
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater then there is no default key size, and the <code class="option">-b</code>
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews<dt><span class="term">-n <em class="replaceable"><code>nametype</code></em></span></dt>
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews Specifies the owner type of the key. The value of
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews <code class="option">nametype</code> must either be ZONE (for a DNSSEC
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews a host (KEY)),
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
2f8d63983c297c62630044d28a6f66676b4d339dMark Andrews These values are case insensitive. Defaults to ZONE for DNSKEY
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater Use an NSEC3-capable algorithm to generate a DNSSEC key.
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater If this option is used and no algorithm is explicitly
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater set on the command line, NSEC3RSASHA1 will be used by

0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater will include the key's creation date in the metadata stored
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater with the private key, and other dates may be set there as well
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater (publication date, activation date, etc). Keys that include
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater this data may be incompatible with older versions of BIND; the
0a7ed88633a680bb881868b75ded4d09a7bbbc50Automatic Updater <code class="option">-C</code> option suppresses them.

5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews Allowed values are 2 and 5. If no generator
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews is specified, a known prime from RFC 2539 will be used
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews if possible; otherwise the default is 2.
