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 as-
sumes this is located at /usr/bin/openssl. This is controlled by the
OPENSSL_BINARY variable. For ed25519 keys, PyNaCl (python-nacl in De-
bian and derivatives) is used. For RSA keys k=sha256 is now included
in the public DNS record to prevent inadvertent use with the now obso-
lete sha1 hash algorithm (See RFC 8301).
USAGE
