Why Client-Side Encryption Matters
Encryption exists to protect data from third parties. If you send your plaintext to a server to be encrypted, you're trusting that server with the very data you're trying to protect.
How DevUtility's AES Encryption Works
DevUtility uses the Web Crypto API's AES-256-GCM algorithm — the same standard used by governments and banks. It generates a random initialization vector (IV) for every encryption, derives the key using PBKDF2 with 100,000 iterations, and performs authenticated encryption that detects tampering.
The Server-Side Problem
Online-Encrypt.com and similar tools send your plaintext over HTTPS to their server for encryption. Even with HTTPS, the server operator can see your data. You're trusting them not to log, store, or misuse it. With DevUtility, there's no trust needed — the code runs in your browser.
Bottom Line
For sensitive data, client-side encryption is the only sane choice. DevUtility gives you military-grade AES-256-GCM without exposing a single byte to any server.
