cdist-type__opendkim_genkey(7)¶

NAME¶

cdist-type__opendkim_genkey - Generate DKIM keys suitable for OpenDKIM

DESCRIPTION¶

This type uses the opendkim-genkey(8) to generate signing keys suitable for usage by opendkim(8) to sign outgoing emails. Then, a line with the domain, selector and keyname in the $selector._domainkey.$domain format will be added to the OpenDKIM key table located at /etc/opendkim/KeyTable. Finally, a line will be added to the OpenDKIM signing table, using either the domain or the provided key for the domain:selector:keyfile value in the table. An existing key will not be overwritten.

Currently, this type is only implemented for Alpine Linux. Please contribute an implementation if you can.

REQUIRED PARAMETERS¶

domain: The domain to generate the key for.
selector: The DKIM selector to generate the key for.

OPTIONAL PARAMETERS¶

bits: The size of the generated key, in bits. The default is 1024, the recommended by the DKIM standard.
directory: The directory in which to generate the key, /var/db/dkim/ by default.
sigkey: The key used in the SigningTable for this signing key. Defaults to the specified domain. If %, OpenDKIM will replace it with the domain found in the From: header. See opendkim.conf(5) for more options.

BOOLEAN PARAMETERS¶

no-subdomains: Disallows subdomain signing by this key.
unrestricted: Do not restrict this key to email signing usage.

    --socket inet:8891@localhost \
    --basedir /var/lib/opendkim \
    --canonicalization relaxed/simple \
    --subdomains no \
