dnssec-keyfromlabel(1M) System Administration Commands dnssec-keyfromlabel(1M)NAMEdnssec-keyfromlabel - DNSSEC key generation tool
SYNOPSISdnssec-keyfromlabel-a algorithm -l label [-c class] [-f flag] [-k]
[-n nametype] [-p protocol] [-t type] [-v level] name
DESCRIPTIONdnssec-keyfromlabel retrieves keys with a specified label from a crypto
hardware device and builds key files for DNSSEC (Secure DNS), as
defined in RFC 2535 and RFC 4034.
OPTIONS
The following options are supported:
-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 that for DNSSEC, RSASHA1 is a mandatory-to-implement algo‐
rithm, and DSA is recommended. Note also that 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 associ‐
ated 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
Displays a short summary of the options and arguments to dnssec-
keyfromlabel.
-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, NOAUTH‐
CONF, 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 displays a string
of the form Knnnn.+aaa+iiiii to the standard output. This is an identi‐
fication string for the key files it has generated, which translates as
follows.
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 dis‐
played string. Knnnn.+aaa+iiiii.key contains the public key, and
Knnnn.+aaa+iiiii.private contains the private key.
The first file contains a DNS KEY record that can be inserted into a
zone file (directly or with an $INCLUDE statement).
The second file contains algorithm-specific fields. For obvious secu‐
rity reasons, this file does not have general read permission.
