DNSSEC-KEYFROMLABEL(8)                              BIND9                             DNSSEC-KEYFROMLABEL(8)



NAME
       dnssec-keyfromlabel - DNSSEC key generation tool

SYNOPSIS
       dnssec-keyfromlabel {-a algorithm} {-l label} [-c class] [-f flag] [-k] [-n nametype] [-p protocol]
                           [-t type] [-v level] {name}

DESCRIPTION
       dnssec-keyfromlabel gets keys with the given label from a crypto hardware and builds key files for
       DNSSEC (Secure DNS), as defined in RFC 2535 and RFC 4034.

OPTIONS
       -a algorithm
           Selects the cryptographic algorithm. The value of algorithm must be one of RSAMD5 (RSA) or
           RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA or DH (Diffie Hellman). These values are case insensitive.

           Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended.

           Note 2: DH automatically sets the -k flag.

       -l label
           Specifies the label of keys in the crypto hardware (PKCS#11 device).

       -n nametype
           Specifies the owner type of the key. The value of nametype 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.

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

       -f flag
           Set the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flag is
           KSK (Key Signing Key) DNSKEY.

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

       -k
           Generate KEY records rather than DNSKEY records.

       -p protocol
           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.

       -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 KEY FILES
       When dnssec-keyfromlabel completes successfully, it prints a string of the form Knnnn.+aaa+iiiii to
       the standard output. This is an identification string for the key files it has generated.

       •   nnnn is the key name.

       •   aaa is the numeric representation of the algorithm.

       •   iiiii is the key identifier (or footprint).

       dnssec-keyfromlabel creates two files, 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.
