9 years ago I discovered how attachments can be sent and received over Mixmaster and nymservers. This needs base64 as a dependency.

I also found bash scripts that automate file conversion to base64 and append it to the message body. nymphemeral could loosely replicate this behavior with python.
Supporting attachments is important for communication flexibility. Can potentially allow sending confidential documents. Nymphemeral should probably manage the attachment file encryption as it does with messages to simplify things for newbies and prevent mistakes.
