Semel Secure Message

Visit seme.li to share expiring secrets once. Encryption and decryption is done exclusively in the browser. No secret reaches the server.

Semper Semel Simplex!

Run your own

This is a 12factor app using the Apt and Crystal Heroku buildpacks. Installation is as easy as clicking this button.

Warning Be aware though that you'll loose your SQLite database often if you use Heroku. You may want to hook into a Postgres database or use Dokku with a volume on your own server. Sticking to a SQLite database also means that you can run on 1 "dyno" only.

Development

Install required prerequisites:

• Crystal >=1.1
• SQLite3
• mkcert

Then run those convenient scripts from the project root:

bin/setup
bin/check
bin/run

FAQ

• Why is there no file upload support?

  File upload capabilities would increase demands for the backend and complexity in general. The idea is rather that you encrypt a file and send it through an insecure channel. You would then only share the encryption key via seme.li.

  If you really want file upload support, you can add it yourself. Have a look at this PR.

  Alternatively I know about the following more bloated (less auditable) alternatives. They all support file uploads:

  • wormhole.app
  • hemmelig.app
  • transferly.swiss
