DNSSEC-IMPORTKEY(8)                 BIND 9                 DNSSEC-IMPORTKEY(8)



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. If the
       argument begins with a + or -, it is interpreted as an offset from the
       present time. For convenience, if such an offset is followed by one of
       the suffixes y, mo, w, d, h, or mi, then the offset 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 or never.

       -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.

       -P 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.)

       -D 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.
