AES Encryption for Web Data - 04/01/2026 10:52 EST
Budget: $10 – $30 USD
I need to integrate robust AES encryption into my current web application so every piece of personal data that moves through the platform is protected end-to-end. The objective is simple: any time a user submits, stores, or retrieves personal information, that data must be encrypted with AES before it ever touches the database or travels across the network.
The codebase is built with standard web technologies (JavaScript on the front end, Node.js on the back). You can work in a different language for the crypto module if it is better suited, as long as you expose clean APIs I can call from Node. Key generation, secure storage, and rotation logic should follow best practices; hard-coding keys is not acceptable.
Deliverables
• AES implementation (256-bit preferred) wired into the existing data flow
• Functions for encrypting and decrypting strings and JSON payloads
• Brief usage guide and comments in the source so future maintenance is straightforward
I’ll spin up a test environment for you right away. Once the encrypted routes pass integration tests and a quick code review, we’re done.
