Summary

In this challenge, you’ll contribute to the heart of Cere’s Developer toolkit: the DDC SDK. Using this SDK, developers interact with Cere’s decentralized data cloud (DDC).

Problem:

• Data is currently stored “as is”. This means developers are responsible for encrypting content before uploading if they feel it’s important.
• Preserving data privacy is important and Cere Network wants to make it as easy as possible for developers to do so.

Proposed Solution (where you can help):

1. Integrate a new functionality into the DDC SDK that allows to encrypt data using one or more encryption algorithms
   1. Both encryption & decryption will happen on the client side
   2. Secure key management is outside the scope
2. Integrate this new functionality into Cere Network’s tooling
   1. There is a Developer Console UI component where this processing option can be invoked.
   2. The same functionality should also be available in the CLI
   3. Both integrations should work using the Cere Wallet

Goal/Values:

• Built-in data privacy
  • Enhance the DDC SDK by introducing built-in encryption capabilities, enabling automatic encryption during uploads and decryption during downloads.
• Privacy by default
  • Making encryption the default option in both the CLI and the Developer Console will ensure all dApps built on Cere Network are safe & secure

Deliverables

• Modified DDC SDK with a configuration-based encryption that support secure encryption algorithm (e.g., AES, ChaCha20, or another suitable method). Users should be able to enable encryption by passing a simple configuration option when initializing the SDK.
• Modified DDC SDK playground showcasing the encryption and decryption
• Modified DDC SDK documentation and examples explaining how to use the new encryption functionality.
• Modified DDC CLI with ability to encrypt content before upload and decrypt content after download (the same upload/download commands but with optional encryption parameter)
• Modified Developer Console that allows user optionally encrypt/decrypt content. One of the options is to use Cere Wallet’s embedded encryption feature (see Tools & Resources section in WIKI for more details).

Technologies

• TypeScript, React, cryptography
