Overview of how to use file repositories.


File repositories are external storage provider (e.g. Google Cloud Storage) that can be used to store encrypted data. The data is encrypted in the browser, and then uploaded to the repository. The data is uploaded directly to the repository without passing through the psono server. The file repository provider has no way to gain access to the decrypted files.


File repository configuration can be shared with other users to allow them to upload something to the providers themself, without the hassle that every use has to configure the repository. The possibility to download a file is controlled similar to the capabilities to access secrets by the share permissions.
