Cryptosak

Design choices

We chose to use AES-256-GCM for encryption and signing, and argon2 for key derivation. We are lazy so everything upladed to the server is stored in RAM.

Client

Commands

• upload <file> <password>
• retreive <id> <password> [out] (optional out parameter to specify output file)

Server

Endpoints

• POST /file - Uploads a file (a EncFile struct serialized as JSON with serde), returns a UploadResponse struct serialized as JSON with serde
• GET /file/<id> - Retrieves a file, returns a RetrieveResponse struct serialized as JSON with serde
