opendkim-genkey
opendkim-genkey(8) System Manager's Manual opendkim-genkey(8) 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. VERSION
This man page covers the version of opendkim-genkey that shipped with version 2.6.8 of OpenDKIM. COPYRIGHT
