Developers implementing client-side encryption face a fundamental challenge: correctly implementing AES encryption requires deep knowledge of key derivation, initialization vectors, and authentication tags. One mistake in parameter selection or implementation can compromise the entire security model. The AES Encryption tool addresses this by providing a reference implementation that handles the cryptographic complexity while keeping sensitive data entirely within the browser.
Why it stands out
Most encryption tools fall into two problematic categories: server-based services that require trusting a third party with your plaintext, or complex libraries that require significant integration work. This tool occupies a unique position — it implements proper AES-GCM encryption with PBKDF2 key derivation using only the Web Crypto API, demonstrating how to build secure encryption without external dependencies.
The implementation choices reflect current cryptographic best practices: AES-GCM for authenticated encryption, PBKDF2 with 100,000 iterations for key stretching, and proper random generation for salts and initialization vectors. As one of 200+ free browser tools on DevTools, it operates with no signup, no tracking — data processed entirely in the browser.
