Glitched Epistle

Windows Client

What is this?

Glitched Epistle is a messaging service that encrypts messages locally (client-side) and submits them to a server-side stored "Convo" (conversation).

• Every message is encrypted using every convo participant's public RSA key individually.
• The server NEVER stores messages in plaintext and DOES NOT under any circumstance know the user's private message decryption key at any given time.
• Requests to the backend are cryptographically signed using 4096-bit RSA keys. For more information, check out the client's shared codebase.

This specific repository here is the Windows client, but anyone can implement any client that communicates over the Epistle backend by using the provided shared codebase (also available as a NuGet package) GlitchedEpistle.Client.

For mobile users: there is also an Android client available on the Google Play Store.

How to set up the development environment:

• Make sure you have Visual Studio >2017 installed with the .NET Framework SDK v4.7.2.
• If you use the SSH URL, make sure you have your git SSH keys set up to authenticate with git correctly!
• Make sure you have git lfs installed and enabled (run git lfs install at least once on your system).
• Navigate to a directory where you wish to clone this repository into.
• Open the command line interface in that folder and execute the following command:

  git clone https://github.com/GlitchedPolygons/GlitchedEpistle.Client.Windows "GlitchedEpistle.Client.Windows"

Where are my messages stored

Your entire Glitched Epistle user data, including settings, convos, metadata and messages are stored inside C:\Users\{YOUR_USERNAME}\AppData\Local\GlitchedPolygons\GlitchedEpistle\{YOUR_EPISTLE_USER_ID}.

The messages are stored (in their encrypted form!) inside SQLite database files inside the Convos/ directory.
