Description

Implement client-side (Flutter) file encryption before upload and decryption after download using libraries like AES or ChaCha20. Ensure keys are securely established or exchanged, possibly using Diffie-Hellman or similar. Update both backend and frontend workflows, and clearly document the encryption flow for users and contributors. Test files for corruption and provide error recovery steps

Contributor guide

Research direction
Review the existing file upload/download flow, then implement encryption using AES or ChaCha20 in the client before upload and after download. Ensure secure key exchange via Diffie Hellman and update both backend and frontend. Write documentation and tests.
