Removes the deref to str as this is now a fallible operation that can panic. Process the fanout of this change, which is dealing with more possibility that things might be binary in more places. There are some transitional APIs introduced as deprecated so that I'm nagged to remove them already: I want to get the bulk of the code aware of the possibility of binary sorted before I tackle adjusting the message parser for that, so that that particular commit is more self-contained.
kumo-dkim
DKIM (RFC6376) implementation
Features
Verifying email signatures
Example:
let res: DKIMResult = kumo_dkim::verify_email(&from_domain, &parsed_email).await?;
if let Some(err) = &res.error() {
error!(logger, "dkim verify fail: {}", err);
}
println!("dkim={}", res.with_detail());
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.
Generate a test DKIM key
Using OpenDKIM:
