Self-destructing messages

Project description

ephemeral - Self-destructing messages

Ephemeral is a web application for sharing short messages. Messages can be opened only once, giving an instant feedback to recipient on whether the message was compromised(read by someone else) or not. This makes the app a reasonably secure, and convenient way to share secrets.


  • Simple, easy-to-audit code
  • Messages are encrypted at rest


pip install ephemeral

After installation you can use the command to start the application (see below).


Always put this application behind an HTTPS-terminating reverse proxy when exposing to public networks!

Ephemeral uses Redis as the data store. Assuming Redis is running on localhost,


will start the application listning on port 8080 on all network interfaces.

Point your browser at http://localhost:8080/add to add a message.



Initialize a virtualenv with dev dependencies installed:

make develop

Project dependencies

Project dependencies shoud always be specified in using the compatible release notation.

Updating dependencies in virtualenv

Run the following after updating

make update-deps

Installing development dependencies

Replace <PACKAGE> with the actual name, and <VERSION> with the MAJOR.MINOR (or MAJOR.MINOR.PATCH for versions below 1.0.0) version of the package. Read more on compatible releases.

pipenv install --dev <PACKAGE>~=<VERSION>

Running unit-tests

make test

Starting a development instance of the application

Start the application in development mode with debugging enabled:

make dev-server

Starting/stopping a development Docker stack

The development Docker (Compose) stack includes Redis container and an application container built from source.


  • Docker
  • docker-compose

(Re)Build the application image, start a stack in background, and show running containers:

make compose-build

make compose-up

make compose-ps

Stop and destroy running stack:

make compose-down

Running E2E tests

Start a stack and run Behave tests against it:

make compose-up

make e2e-test

Starting a release


  • RELEASE_REMOTE set to the name of the Git remote. Set to empty to disable pushes to remote. Default value: origin
  • RELEASE_VERSION override the release version, or leave empty to release the current snapshot (-SNAPSHOT will be stripped off). Empty by default
make release-start

Finishing a release


  • RELEASE_REMOTE set to the name of the Git remote. Set to empty to disable pushes to remote. Default value: origin
  • RELEASE_PUBLISH set to 1 to enable publishing of the sdist tarball after the release`
make release-finish

release-finish will leave the release Git tag checked out on completion.

Building and publishing the source distribution:

make publish
