Data Security: Building Architecture When Integrating Encryption Algorithms
summary
Aleksey presents a financial accounting app for SMBs built with React, Redux and TypeScript that emphasizes end-to-end data security beyond backend protections. He compares services’ support for encryption, identifies common client-side attack vectors (XSS, CSRF, bruteforce), and describes an architecture that keeps data inaccessible to the system while allowing server-side computation and math over encrypted data using RSA, AES and the Paillier cryptosystem, implemented with RxJS, Web Workers and WebAssembly.
