dnssec-keyfromlabel — DNSSEC key generation tool
dnssec-keyfromlabel {-a algorithm} {-l label} [-c ] [class-f ] [flag-k] [-n ] [nametype-p ] [protocol-t ] [type-v ] {name}level
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.
algorithm
Selects the cryptographic algorithm. The value of
algorithm must be one of RSAMD5,
RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256,
RSASHA512 or DH (Diffie Hellman).
These values are case insensitive.
If no algorithm is specified, then RSASHA1 will be used by
default, unless the -3 option is specified,
in which case NSEC3RSASHA1 will be used instead. (If
-3 is used and an algorithm is specified,
that algorithm will be checked for compatibility with NSEC3.)
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended.
Note 2: DH automatically sets the -k flag.
labelSpecifies the label of keys in the crypto hardware (PKCS#11 device).
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.
classIndicates that the DNS record containing the key should have the specified class. If not specified, class IN is used.
flagSet the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flag is KSK (Key Signing Key) DNSKEY.
Prints a short summary of the options and arguments to dnssec-keygen.
Generate KEY records rather than DNSKEY records.
protocolSets 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.
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.
levelSets the debugging level.
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.
