nymphemeral 1.3.5

An ephemeral nym GUI client

nymphemeral

nymphemeral is a tool made for users searching for secure and anonymous communication on the internet.

It is a GUI client that relies on a pseudonymous remailer that communicates to its users by posting messages to a shared mailbox, a Zax-type nym server. Both the server and the client apply an ephemeral encryption layer on their messages based on the Axolotl Ratchet protocol, providing forward and future secrecy to the conversation.

Features

• Manages pseudonymous actions: creation, configuration and deletion, as well as message dispatch and retrieval

• Communicates with the new nymserv, a Zax-type nym server with forward secrecy

• Uses python-gnupg and pyaxo for encryption

• Uses aampy to retrieve messages from alt.anonymous.messages

• Sends messages through Mixmaster, sendmail, or outputs the resulting ciphertexts to be sent manually

• Supports End-to-End Encryption

Current Release

The current version of nymphemeral is 1.3.5, a beta, released 2015-09-09.

Quick Install

If you use pip, you can easily install nymphemeral with:

sudo pip install nymphemeral

You should at least read news server to make sure you have one running and configured so that your nyms can receive messages.

Documentation

You can find installation and usage instructions (with screenshots) on the documentation, as well as nymphemeral’s limitations.

Protocol Update

nymphemeral 1.3.3 was updated to use pyaxo 0.4 that follows the latest (Oct 1, 2014) version of the protocol, which changed the order of the ratcheting. For that reason, old conversations (created with nymphemeral < 1.3.3) might not work properly after the update. We suggest that users update nymphemeral and restart their conversations by changing their nyms’ ephemeral keys. The Configuring the Nym section explains how that can be done.
