π HOW THE ENCRYPTION WORKS
1. You select text and click "Upload to OctoPaste"
2. A random 128-bit AES encryption key is generated in your browser
3. Your content is encrypted locally using AES-128-GCM
4. Only the encrypted blob is sent to our servers
5. The decryption key is added to the URL after the # symbol
6. Browsers NEVER send the # fragment (URL hash) to servers
7. Only someone with the complete URL can decrypt your content
The encryption key exists only in the URL fragment. This means:
- The server never receives your key
- We cannot decrypt your pastes
- Your data remains private even from us
