.TH dknewkey 1 "2018-02-05"
.SH "NAME"
dknewkey
\-
Generates new DKIM public/private key pairs
.SH "VERSION"
0\.8\.0

.SH "DESCRIPTION"

dknewykey generates new DKIM keys.

For RSA keys, it defaults to 2048 bit key size.  This is controlled by the
BITS_REQUIRED variable. ed25519 keys do not have a variable size.

For RSA keys, it uses openssl to do the generation.  By default it assumes
this is located at /usr/bin/openssl.  This is controlled by the OPENSSL_BINARY
variable.  For ed25519 keys, PyNaCl (python-nacl in Debian and derivatives) is
used.  For RSA keys k=sha256 is now included in the public DNS record to
prevent inadvertent use with the now obsolete sha1 hash algorithm (See RFC
8301).

.SH "USAGE"

dknewkey.py [\-h] [\-\-ktype {rsa,ed25519}] key_name

mandatory positional arguments:
  key_name

optional arguments:
  \-h, \-\-help            show this help message and exit
  \-\-ktype {rsa,ed25519}
                        DKIM key type: Default is rsa

NOTE: Depending on the packaging and distribution, the exact path and name for
the executable may vary.
