✨ Store Encryption Package File in Mongo

[lprichar]

Is there an existing issue for this?

• I have searched the existing issues

Suggestion

The encryption package is currently saved in the file system because Mongo doesn't support file sizes over 16 Meg. However, storing it in the database would be cleaner.

Possible Implementation

Use GridFS: https://www.mongodb.com/docs/manual/core/gridfs/

Anything else?
