F-Droid repository metadata
This software enables you to transparently encrypt your Dropbox folder on your PC. It also lets you confirm the decryption operations on an Android smartphone, which is used as an NFC-enabled token. Additionally, it supports sharing files with other Dropbox users, while still encrypting the shared data. To really use the app, you also need to install the encrypting program on your PC. It can be found in the source code repository.
How to install
- Download the APK from the button at the top of this page.
- Allow “Install unknown apps” for your browser or file manager only, not for every app.
- Open the downloaded file and confirm the installation.
- If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
