Signing and validation
📄️ Signing with S/MIME
The implementation code is available in our code repository.
📄️ Signing with BATV
The implementation code is available in our code repository.
📄️ Signing with DKIM
The Halon platform has support for DKIM (DomainKeys Identified Mail) which is based on our open source DKIM library. DKIM provides cryptographic mechanisms to verify the integrity of a message. A DKIM-signed message includes a DKIM-Signature header which contains a message signature that is based on public-key cryptography. DKIM uses DNS(SEC) as a carrier to provide the public keys.
📄️ Deploying DMARC
The Halon platform has support for DMARC (Domain-based Message Authentication, Reporting and Conformance); the first widely deployed technology that can make the "From" header (what users see as the sender address in their e-mail clients) trustworthy.
