1494N/A generates keys for DNSSEC (Secure DNS), as defined in RFC 2535
1494N/A and RFC 4034. It can also generate keys for use with
1494N/A TSIG (Transaction Signatures), as defined in RFC 2845.

1494N/A Selects the cryptographic algorithm. The value of
1494N/A <
code class="option">algorithm</
code> must be one of RSAMD5 (RSA) or RSASHA1,
1494N/A DSA, NSEC3RSASHA1, NSEC3DSA, DH (Diffie Hellman), or HMAC-MD5.
1494N/A These values are case insensitive.
1494N/A Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
1494N/A algorithm, and DSA is recommended. For TSIG, HMAC-MD5 is
1494N/A Note 2: HMAC-MD5 and DH automatically set the -k flag.

1494N/A Specifies the number of bits in the key. The choice of key
1494N/A size depends on the algorithm used. RSAMD5 / RSASHA1 keys must be
1494N/A 512 and 2048 bits. Diffie Hellman keys must be between
1494N/A 128 and 4096 bits. DSA keys must be between 512 and 1024
1494N/A bits and an exact multiple of 64. HMAC-MD5 keys must be

1494N/A Allowed values are 2 and 5. If no generator

1494N/A if possible; otherwise the default is 2.

1494N/A Sets the protocol value for the generated key. The protocol
1494N/A is a number between 0 and 255. The default is 3 (DNSSEC).
1494N/A Other possible values for this argument are listed in
1494N/A RFC 2535 and its successors.

1494N/A one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
1494N/A is AUTHCONF. AUTH refers to the ability to authenticate
1494N/A data, and CONF the ability to encrypt data.
