DNSSEC-IMPORTKEY(1) BIND 9 DNSSEC-IMPORTKEY(1)

NAME

dnssec-importkey - import DNSKEY records from external systems so
they can be managed

SYNOPSIS

dnssec-importkey [-K directory] [-L ttl] [-P date/offset] [-P sync
date/offset] [-D date/offset] [-D sync date/offset] [-h] [-v level]
[-V] {keyfile}

dnssec-importkey {-f filename} [-K directory] [-L ttl] [-P
date/offset] [-P sync date/offset] [-D date/offset] [-D sync
date/offset] [-h] [-v level] [-V] [dnsname]

DESCRIPTION

dnssec-importkey reads a public DNSKEY record and generates a pair of
.key/.private files. The DNSKEY record may be read from an existing
.key file, in which case a corresponding .private file is generated,
or it may be read from any other file or from the standard input, in
which case both .key and .private files are generated.

The newly created .private file does not contain private key data,
and cannot be used for signing. However, having a .private file makes
it possible to set publication (-P) and deletion (-D) times for the
key, which means the public key can be added to and removed from the
DNSKEY RRset on schedule even if the true private key is stored
offline.

OPTIONS

-f filename
This option indicates the zone file mode. Instead of a public
keyfile name, the argument is the DNS domain name of a zone
master file, which can be read from filename. If the domain
name is the same as filename, then it may be omitted.

If filename is set to "-", then the zone data is read from the
standard input.

-K directory
This option sets the directory in which the key files are to
reside.

-L ttl This option sets the default TTL to use for this key when it
is converted into a DNSKEY RR. This is the TTL used when the
key is imported into a zone, unless there was already a DNSKEY
RRset in place, in which case the existing TTL takes
precedence. Setting the default TTL to 0 or none removes it
from the key.

-h This option emits a usage message and exits.

-v level
This option sets the debugging level.

-V This option prints version information.

TIMING OPTIONS

Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
(which is the format used inside key files), or 'Day Mon DD HH:MM:SS
YYYY' (as printed by dnssec-settime -p), or UNIX epoch time (as
printed by dnssec-settime -up), or the literal now.

The argument can be followed by + or - and an offset from the given
time. The literal now can be omitted before an offset. The offset can
be followed by one of the suffixes y, mo, w, d, h, or mi, so that it
is computed in years (defined as 365 24-hour days, ignoring leap
years), months (defined as 30 24-hour days), weeks, days, hours, or
minutes, respectively. Without a suffix, the offset is computed in
seconds.

To explicitly prevent a date from being set, use none, never, or
unset.

All these formats are case-insensitive.

-P date/offset
This option sets the date on which a key is to be published to
the zone. After that date, the key is included in the zone but
is not used to sign it.

sync date/offset
This option sets the date on which CDS and CDNSKEY
records that match this key are to be published to the
zone.

-D date/offset
This option sets the date on which the key is to be deleted.
After that date, the key is no longer included in the zone.
(However, it may remain in the key repository.)

sync date/offset
This option sets the date on which the CDS and CDNSKEY
records that match this key are to be deleted.

FILES

A keyfile can be designed by the key identification Knnnn.+aaa+iiiii
or the full file name Knnnn.+aaa+iiiii.key, as generated by
dnssec-keygen.
