It was a small, focused library — a JavaScript/TypeScript counterpart to <a href="https://github.com/ecies/py">eciespy</a> — born from a simple gap: the JavaScript ecosystem needed a clean, correct Elliptic Curve Integrated Encryption Scheme implementation.</p> <p>Seven years and fifty releases later, the core API is still two functions: <code>encrypt</code> and <code>decrypt</code>. That simplicity is deliberate. Cryptographic libraries should be boring — prevent misuse and get out of your way.</p>
