ocaml-dkim
ocaml-dkim
is a pure implementation of DKIM in OCaml. It permits to verify and sign an incoming email. It can be use as a SMTP filter service (verify) or as a SMTP submission service (sign).
How to install it?
You must have an OPAM environment. Then, ocaml-dkim
can be installed with:
$ opam pin add https://github.com/dinosaure/ocaml-dkim.git
How to use it?
ocaml-dkim
provides 2 binaries, one to verify, the second to sign an email.
$ dkim.verify test/raw/001.mail
[ok]: sendgrid.info
[ok]: github.com
It shows all domains which signed the given email and whether the signature is correct or not (for the last case, it shows you the selector). ocaml-dkim
is able to sign an email from a private RSA key and a specific domain such as:
$ dkim.sign -k private-key.pem --selector admin --hostname x25519.net test/raw/001.mail
DKIM-Signature: ...
Rest of the email
It prints the signed email then. The user is able to use a specific RSA private key or it can use a seed used to generate the RSA private key with the fortuna random number generator.
