d71e2e0c61df16ff37c9934c371a4a60c08974f7Mark Andrews and RFC 4034. It can also generate keys for use with

ad671240d635376dd8681550eebee799d2e3d1fdAutomatic Updater The <code class="option">name</code> of the key is specified on the command
ad671240d635376dd8681550eebee799d2e3d1fdAutomatic Updater line. For DNSSEC keys, this must match the name of the zone for

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,
cd791043c8a6edbcacc2392575a9816d19b8157cTinderbox User DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512, ECCGOST,
cd791043c8a6edbcacc2392575a9816d19b8157cTinderbox User ECDSAP256SHA256 or ECDSAP384SHA384.
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,
8e821eea5f57ac47a94305aa7ab0c3570d92a311Automatic Updater in which case NSEC3RSASHA1 will be used instead. (If
8e821eea5f57ac47a94305aa7ab0c3570d92a311Automatic Updater <code class="option">-3</code> is used and an algorithm is specified,
8e821eea5f57ac47a94305aa7ab0c3570d92a311Automatic Updater that algorithm will be checked for compatibility with NSEC3.)
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

5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews Specifies the number of bits in the key. The choice of key
8e821eea5f57ac47a94305aa7ab0c3570d92a311Automatic Updater size depends on the algorithm used. RSA 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
8e821eea5f57ac47a94305aa7ab0c3570d92a311Automatic Updater bits and an exact multiple of 64. HMAC keys must be
cd791043c8a6edbcacc2392575a9816d19b8157cTinderbox User between 1 and 512 bits. Elliptic curve algorithms don't need
cd791043c8a6edbcacc2392575a9816d19b8157cTinderbox User this parameter.
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

5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews <code class="option">nametype</code> must either be ZONE (for a DNSSEC
