dnssec-keyfromlabel
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.
o nnnn is the key name.
o aaa is the numeric representation of the algorithm.
o 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.
