cfdkim
DKIM (RFC6376) implementation
Features
Verifying email signatures
Example:
let res: DKIMResult = cfdkim::verify_email(&logger, &from_domain, &parsed_email).await?;
if let Some(err) = &res.error() {
error!(logger, "dkim verify fail: {}", err);
}
println!("dkim={}", res.with_detail());
The verify_email arguments are the following:
Signing an email
Example:
let private_key =
rsa::RsaPrivateKey::read_pkcs1_pem_file(Path::new("./test/keys/2022.private"))?;
let signer = SignerBuilder::new()
.with_signed_headers(["From", "Subject"])?
.with_private_key(private_key)
.with_selector("2020")
.with_signing_domain("example.com")
.build()?;
let signature = signer.sign(&email)?;
println!("{}", signature); // DKIM-Signature: ...
See the SignerBuilder object documentation for more information.
