How the encryption works

Step 1
🔑
A secret key is generated

Before anything is sent, your browser creates a unique 256-bit encryption key. It never leaves your device.

Step 2
🔒
Your file is locked locally

Your file is encrypted on your device using AES-256-GCM - the same standard used by banks and governments. Only then is it uploaded.

Step 3
📡
We only receive noise

What arrives on our servers is unreadable data. We cannot see your files. Nobody can - not even us.

Step 4
🔗
The key travels in the link

The decryption key is embedded after the # in your download link. Browsers never send this part to any server. Only your recipient has it.
