- <title>DESCRIPTION</title>
- <para>
- <command>dnssec-keygen</command> generates keys for DNSSEC
- (Secure DNS), as defined in RFC 2535 and RFC &lt;TBA\&gt;. It can also generate
- keys for use with TSIG (Transaction Signatures), as
- defined in RFC 2845.

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

- </varlistentry>
-
- <varlistentry>
- <term>-b <replaceable class="parameter">keysize</replaceable></term>
- <listitem>
- <para>
- Specifies the number of bits in the key. The choice of key
- size depends on the algorithm used. RSAMD5 / RSASHA1 keys must be between
- 512 and 2048 bits. Diffie Hellman keys must be between
- 128 and 4096 bits. DSA keys must be between 512 and 1024
- bits and an exact multiple of 64. HMAC-MD5 keys must be
- between 1 and 512 bits.

- </varlistentry>
-
- <varlistentry>
- <term>-n <replaceable class="parameter">nametype</replaceable></term>
- <listitem>
- <para>
- Specifies the owner type of the key. The value of
- <option>nametype</option> must either be ZONE (for a DNSSEC
- zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)),
- USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). These values are
- case insensitive.
- </para>

-
- <varlistentry>
- <term>-c <replaceable class="parameter">class</replaceable></term>
- <listitem>
- <para>
- Indicates that the DNS record containing the key should have
- the specified class. If not specified, class IN is used.

- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>-e</term>
- <listitem>
- <para>
- If generating an RSAMD5/RSASHA1 key, use a large exponent.

- </varlistentry>
-
- <varlistentry>
- <term>-f <replaceable class="parameter">flag</replaceable></term>
- <listitem>
- <para>
- Set the specified flag in the flag field of the KEY/DNSKEY record.
- The only recognized flag is KSK (Key Signing Key) DNSKEY.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>-g <replaceable class="parameter">generator</replaceable></term>
- <listitem>
- <para>
- If generating a Diffie Hellman key, use this generator.
- Allowed values are 2 and 5. If no generator
- is specified, a known prime from RFC 2539 will be used
- if possible; otherwise the default is 2.
- </para>
- </listitem>
- </varlistentry>

- Generate KEY records rather than DNSKEY records.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>-p <replaceable class="parameter">protocol</replaceable></term>
- <listitem>
- <para>
- Sets the protocol value for the generated key. The protocol
- is a number between 0 and 255. The default is 3 (DNSSEC).
- Other possible values for this argument are listed in
- RFC 2535 and its successors.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>-r <replaceable class="parameter">randomdev</replaceable></term>
- <listitem>
- <para>
- Specifies the source of randomness. If the operating
- system does not provide a <filename>/dev/random</filename>
- or equivalent device, the default source of randomness
- is keyboard input. <filename>randomdev</filename> specifies
- the name of a character device or file containing random
- data to be used instead of the default. The special value
- <filename>keyboard</filename> indicates that keyboard
- input should be used.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>-s <replaceable class="parameter">strength</replaceable></term>
- <listitem>
- <para>
- Specifies the strength value of the key. The strength is
- a number between 0 and 15, and currently has no defined
- purpose in DNSSEC.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>-t <replaceable class="parameter">type</replaceable></term>
- <listitem>
- <para>
- Indicates the use of the key. <option>type</option> must be
- one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
- is AUTHCONF. AUTH refers to the ability to authenticate
- data, and CONF the ability to encrypt data.

- <title>GENERATED KEYS</title>
- <para>
- When <command>dnssec-keygen</command> completes successfully,
- it prints a string of the form <filename>Knnnn.+aaa+iiiii</filename>
- to the standard output. This is an identification string for
- the key it has generated.
- </para>
- <itemizedlist>
- <listitem>
- <para>
- <filename>nnnn</filename> is the key name.
- </para>
- </listitem>
- <listitem>
- <para>
- <filename>aaa</filename> is the numeric representation of the
- algorithm.
- </para>
- </listitem>
- <listitem>
- <para>
- <filename>iiiii</filename> is the key identifier (or footprint).
- </para>
- </listitem>
- </itemizedlist>
- <para>
- <command>dnssec-keygen</command> creates two file, with names based
- on the printed string. <filename>Knnnn.+aaa+iiiii.key</filename>
- contains the public key, and
- <filename>Knnnn.+aaa+iiiii.private</filename> contains the private
- key.
- </para>
- <para>
- The <filename>.key</filename> file contains a DNS KEY record that
- can be inserted into a zone file (directly or with a $INCLUDE
- statement).
- </para>
- <para>
- The <filename>.private</filename> file contains algorithm specific
- fields. For obvious security reasons, this file does not have
- general read permission.
- </para>
- <para>
- Both <filename>.key</filename> and <filename>.private</filename>
- files are generated for symmetric encryption algorithm such as
- HMAC-MD5, even though the public and private key are equivalent.

- <title>EXAMPLE</title>
- <para>
- To generate a 768-bit DSA key for the domain
- <userinput>example.com</userinput>, the following command would be
- issued:
- </para>
- <para>
- <userinput>dnssec-keygen -a DSA -b 768 -n ZONE example.com</userinput>
- </para>
- <para>
- The command would print a string of the form:
- </para>
- <para>
- <userinput>Kexample.com.+003+26160</userinput>
- </para>
- <para>
- In this example, <command>dnssec-keygen</command> creates
- the files <filename>Kexample.com.+003+26160.key</filename> and
- <filename>Kexample.com.+003+26160.private</filename>
