How the Encryption Works

STEP 01

Generate Keys

Your RSA-4096 key pair is generated locally. The private key never leaves your browser.

STEP 02

Share Public Key

Share your public key with anyone who should send you encrypted messages or files.

STEP 03

Encrypt

A random AES-256 session key is created, encrypts your data, then is itself encrypted with RSA.

STEP 04

Decrypt

Only the holder of the matching private key can unwrap the session key and decrypt the payload.
