NAME

dknewkey - Generates new DKIM public/private key pairs

VERSION

0.8.0

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).

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.
