Murmur

Encrypt a message in your browser and share it as a link. Nothing is uploaded to a server.

Create a link

Pick a passphrase. Anyone with the link and passphrase can decrypt the message.

How it works

  • Encryption: PBKDF2 (SHA-256) + AES-GCM.
  • Storage: the encrypted payload lives in the URL fragment.
  • Passphrase: never included in the URL.

Heads up

Links can get very long. For best results, keep messages short and avoid sharing in places that may truncate URLs.
