NAME

       opendkim-genkey - DKIM filter key generation tool

SYNOPSIS

       opendkim-genkey [options]

DESCRIPTION

       opendkim-genkey	generates  (1)	a  private key for signing messages using opendkim(8) and (2) a DNS TXT record suitable for inclusion in a
       zone file which publishes the matching public key for use by remote DKIM verifiers.

       The filenames of these are based on the selector (see below); the private key will have a suffix of ".private" and the TXT record will have
       a suffix of ".txt".

OPTIONS

       -a     Appends  the  domain  name (see -d below) to the label in the generated TXT record, followed by a trailing period.  By default it is
	      assumed the domain name is implicit from the context of the zone file, and is therefore not included in the output.

       -b bits
	      Specifies the size of the key, in bits, to be generated.	The default is 1024 which is the value recommended by the DKIM	specifica-
	      tion.

       -d domain
	      Names  the  domain  which  will  use this key for signing.  Currently only used in a comment in the TXT record file.  The default is
	      "example.com".

       -D directory
	      Instructs the tool to change to the named directory prior to creating files.  By default the current directory is used.

       -h algorithms
	      Specifies a list of hash algorithms which can be used with this key.  By default all hash algorithms are allowed.

       -n note
	      Includes arbitrary note text in the key record.  By default, no such text is included.

       -r     Restricts the key for use in e-mail signing only.  The default is to allow the key to be used for any service.

       -s selector
	      Specifies the selector, or name, of the key pair generated.  The default is "default".

       -S     Disallows subdomain signing by this key.	By default the key record will be generated such that verifiers are told subdomain signing
	      is permitted.

       -t     Indicates the generated key record should be tagged such that verifiers are aware DKIM is in test at the signing domain.

NOTES

       Requires that the openssl(8) binary be installed and in the executing shell's search path.

NAME

       opendkim-atpszone - DKIM ATPS zone file generation tool

SYNOPSIS

       opendkim-atpszone  [-A]	[-C  address]  [-E  secs]  [-h	hash]  [-N  ns[,...]]  [-o file] [-r secs] [-R secs] [-S] [-t secs] [-T secs] [-v]
       [dataset]

DESCRIPTION

       opendkim-atpszone generates a file suitable for use with named(8) to publish a set of domains authorized as third-party signers for a local
       domain.

       The dataset parameter should specify a set of data as described in the opendkim(8) man page.  It can currently refer to flat files, Sleepy-
       cat databases, comma-separated lists, LDAP directories or SQL databases.  The keys in the named database are assumed to comprise a  set	of
       domains	that  are  to be advertised using the experimental Authorized Third-Party Signers protocol as permitted to sign mail using DKIM on
       behalf of the local domain.  Values in the database are not used.

OPTIONS

       -A     Adds a "._atps" suffix to records in the zone file.

       -C contact
	      Uses contact as the contact information to be used when an SOA record is generated (see -S below).  If not specified, the userid	of
	      the executing user and the local hostname will be used; if the executing user can't be determined, "hostmaster" will be used.

       -E secs
	      When generating an SOA record (see -S below), use secs as the default record expiration time.  The default is 604800.

       -h hash
	      Specifies  which	SHA  hash  algorithm to use.  Must be one of "none", "sha1" and "sha256", with "sha256" being the default if it is
	      available.

       -N nslist
	      Specifies a comma-separated list of nameservers, which will be output in NS records before the TXT records.  The first nameserver in
	      this list will also be used in the SOA record (if -S is also specified) as the authority hostname.

       -o file
	      Sends output to the named file rather than standard output.

       -r secs
	      When generating an SOA record (see -S below), use secs as the zone refresh time.	The default is 10800.

       -R secs
	      When generating an SOA record (see -S below), use secs as the zone retry time.  The default is 1800.

       -S     Asks for an SOA record to be generated at the top of the output.	The content of this output can be controlled using the -E, -r, -R,
	      -T options.  The serial number will be generated based on the current time of day.

       -t ttl Puts a TTL (time-to-live) value of ttl on all records output.  The units are in seconds.

       -T secs
	      When generating an SOA record (see -S below), use secs as the default record TTL time.  The default is 86400.

       -v     Increases the verbosity of debugging output written to standard error.
