PrivateTalk – Secure Identity

Send and receive fully private messages using your own public and private keys. Your keys never leave your browser.
Back to PrivateTalk
Here you can write and encrypt a message for a public key (PTPUB1). Only someone with the corresponding private key will be able to read it.
Quick Instructions
Messaging
  • To write: In the left block, paste the recipient’s PTPUB1, write your message, and click “Generate secure link”.
  • To read: Open a link containing ?id=...&rt=.... The left block will switch to “Read message” and ask for your PTPRIV1.
  • Privacy: Private keys and plaintext messages never leave your browser. The server only stores the encrypted blob and minimal metadata.
  • Message destruction: After a successful read, the message is permanently deleted from the server.
Identity creation
  • Generate keys: In the right block, click “Generate new key pair” to create your PTPUB1 (public) and PTPRIV1 (private) keys.
  • Public key: Starts with PTPUB1:. Share it with others so they can send you encrypted messages.
  • Private key: Starts with PTPRIV1:. Keep it secret — never share it. Use it to decrypt messages sent to your public key.
  • Backup: Download your private key as a .key file or copy it manually. Without it, you will not be able to read messages sent to you.
