Large file partial encryption proof of concept

Inspiration

The inspiration behind the application came from the need to address the challenge of efficiently encrypting large files. The goal was to create a proof of concept for chunk encryption in React, exploring methods to handle the encryption of files in a way that is scalable and resource-efficient.

What it does

The application demonstrates a proof of concept for chunk encryption of large files. It divides a large file into smaller, manageable chunks and encrypts 5MB every 10MB, ensuring more efficient memory usage and processing. This approach enables the secure handling of large files in a resource-conscious manner.

How we built it

The application was built using the React framework, leveraging its component-based architecture for creating a user interface. File handling and encryption logic were implemented using JavaScript, and a tweetnacl npm package, specifically designed for cryptographic operations, was incorporated to enhance efficiency and security. The process involved breaking down the file into chunks, encrypting chunk, and combining them into a secure format for storage or transmission.

Challenges we ran into

Efficiently managing memory and processing for large files posed a key challenge. Balancing encryption granularity with overall performance required careful consideration throughout the development process.

Accomplishments that we're proud of

What we learned

The project provided valuable insights into handling large files in a web-based environment and implementing cryptographic operations in a resource-efficient manner.

What's next for Large file partial encryption proof of concept

The next steps for the proof of concept involve further optimization and refinement of the segmented encryption process. The plan is to encapsulate the logic into a dedicated BOS component, enhancing modularity and reusability. This component will encapsulate the file handling, segmentation, and encryption logic, allowing for easier integration with other parts of the application and providing a foundation for future feature enhancements.
