About RSA
Asymmetric — Two keys: anyone encrypts with your public key, only you decrypt with your private key.
Web Crypto API — Hardware-accelerated, built into your browser. Nothing leaves your device.
Key sizes — 2048-bit is standard. 4096-bit offers stronger long-term security but is slower to generate.
