Description: Implementation of RFC-4871 (DomainKeys Identified Mail)
.
The DKIM project is a portable library that signs and verifies emails using
the OpenSSL library.
.
DomainKeys Identified Mail (DKIM) defines a domain-level authentication
framework for email using public-key cryptography and key server technology
to permit verification of the source and contents of messages by either Mail
Transport Agents (MTAs) or Mail User Agents (MUAs).
.
Ok..., what does that mean?
.
Let's break it down into chunks:
- ... domain-level authentication framework for email
DKIM uses DNS to store the public key and policy information.
This information can be used to validate an identity associated with an
email message.
- using public-key cryptography and key server technology
The DKIM signing algorithm computes a SHA-1 hash of the message header
and body and encrypts it using the RSA algorithm and the private key.
This signature is stored in the DKIM-Signature: header of the email.
- permit verification of ...
DKIM uses the public key from DNS to decrypt the signature and compares
the hash to one computed from the email message.
.
This package contains only a small executable for generating / verifying
DKIM headers.
