dnssec-keygen

DNSSEC-KEYGEN(8)														  DNSSEC-KEYGEN(8)

NAME

       dnssec-keygen - DNSSEC key generation tool

SYNOPSIS

       dnssec-keygen  -a  algorithm -b keysize -n nametype [ -c class ]  [ -e ]  [ -g generator ]  [ -h ]  [ -p protocol ]  [ -r randomdev ]  [ -s
       strength ]  [ -t type ]	[ -v level ]  name

DESCRIPTION

       dnssec-keygen generates keys for DNSSEC (Secure DNS), as defined in RFC 2535. It can also generate keys for use with TSIG (Transaction Sig-
       natures), as defined in RFC 2845.

OPTIONS

       -a algorithm
	      Selects  the  cryptographic  algorithm.  The value of algorithm must be one of RSAMD5 or RSA, DSA, DH (Diffie Hellman), or HMAC-MD5.
	      These values are case insensitive.

	      Note that for DNSSEC, DSA is a mandatory to implement algorithm, and RSA is recommended. For TSIG, HMAC-MD5 is mandatory.

       -b keysize
	      Specifies the number of bits in the key. The choice of key size depends on the algorithm used. RSA 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.

       -n nametype
	      Specifies the owner type of the key. The value of nametype must either be ZONE (for a DNSSEC zone key), HOST or ENTITY  (for  a  key
	      associated with a host), or USER (for a key associated with a user). These values are case insensitive.

       -c class
	      Indicates that the DNS record containing the key should have the specified class. If not specified, class IN is used.

       -e     If generating an RSA key, use a large exponent.

       -g generator
	      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.

       -h     Prints a short summary of the options and arguments to dnssec-keygen.

       -p protocol
	      Sets the protocol value for the generated key. The protocol is a number between 0 and 255. The default is 2 (email) for keys of type
	      USER and 3 (DNSSEC) for all other key types.  Other possible values for this argument are listed in RFC 2535 and its successors.

       -r randomdev
	      Specifies  the source of randomness. If the operating system does not provide a /dev/random or equivalent device, the default source
	      of randomness is keyboard input. randomdev specifies the name of a character device or  file  containing	random	data  to  be  used
	      instead of the default. The special value keyboard indicates that keyboard input should be used.

       -s strength
	      Specifies the strength value of the key. The strength is a number between 0 and 15, and currently has no defined purpose in DNSSEC.

       -t type
	      Indicates  the  use of the key. type 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.

       -v level
	      Sets the debugging level.

GENERATED KEYS

       When dnssec-keygen completes successfully, it prints a string of the form Knnnn.+aaa+iiiii to the standard output. This is  an  identifica-
       tion string for the key it has generated. These strings can be used as arguments to dnssec-makekeyset.

       o nnnn is the key name.

       o aaa is the numeric representation of the algorithm.

       o iiiii is the key identifier (or footprint).

       dnssec-keygen   creates	 two  file,  with  names  based  on  the  printed  string.  Knnnn.+aaa+iiiii.key  contains  the  public  key,  and
       Knnnn.+aaa+iiiii.private contains the private key.

       The .key file contains a DNS KEY record that can be inserted into a zone file (directly or with a $INCLUDE statement).

       The .private file contains algorithm specific fields. For obvious security reasons, this file does not have general read permission.

       Both .key and .private files are generated for symmetric encryption algorithm such as HMAC-MD5, even though the public and private key  are
       equivalent.

EXAMPLE

       To generate a 768-bit DSA key for the domain example.com, the following command would be issued:

       dnssec-keygen -a DSA -b 768 -n ZONE example.com

       The command would print a string of the form:

       Kexample.com.+003+26160

       In this example, dnssec-keygen creates the files Kexample.com.+003+26160.key and Kexample.com.+003+26160.private
