 Python module that implements DKIM (DomainKeys Identified Mail) email signing
 and verification. It also provides helper scripts for command line signing
 and verification. As of version 0.6.0, it also supports the experimental Authenticated Received Chain (ARC) protocol.

Originally developed by Greg Hewgill - The code in this project has been modified and development work continued. This is now a fork of pydkim and we've renamed it dkimpy to avoid confusion. The original author of pydkim has confirmed he no longer intends to maintain it and supports this as its continuation.

Current documentation is available online at

ARC is still in development. dkimpy 0.6.0 supports draft with the exception of requiring 1024 bit minimum key size (this matches the planned changes in the next update).
