Encrypt It. Compute on Ciphertext. Decrypt It.
Paste data below. It encrypts live in your browser with real AES-256-GCM. The computation-on-ciphertext step is illustrative — it depicts how the production H33 FHE Platform computes on encrypted data without decrypting it. Verify the real FHE in the Proof Lab.
