Simple implementation of client side encryption for file upload with backblaze as storage backend.
When uploading a file it will be encrypted client side with the AES algorithm using a randomly generated key. Then it will be uploaded to the server and made available through a unique URL containing the file id and the key.
If you lose the key you will not be able to decrypt the file.
The project uses MongoDB, Flask and Backblaze.
You will need to get a backblaze account on https://www.backblaze.com/ and get three informations : the account id, the account key and the bucket id.
When this is done you must put them in your environement whith the name specified in the config file. You can also put them in a .env file at the repository root level if you want to launch the server with docker-compose.
You can launch the server using docker-compose up.
$ virtualenv env
$ source env/bin/active
$ pip install -r requirements.txt
$ python run.py
The web server is listenning on the port 5000 by default.
