An ephemeral secret sharing tool
Send an encrypted secret, retrieve it once, and it’s gone forever!
Send this link to a friend. When they click on it your message will be displayed and deleted.
- Enter plain-text into the box above
- Click the ENCRYPT button ... a secure link is then generated
- Send the link to someone using your preferred method of communication
Encryption keys are never sent to or stored on our servers.
Generated links use the URL anchor (#) tag for encryption IV's and encryption keys. This ensures the server never knows the encryption keys. We could not recover your note even if we wanted to.
Notes are permanently deleted from our servers after one view.
Cryptographic authentication is not performed. This means that BlackNote cannot verify who sent or who is reading the note.
As such, your trust that the author of the BlackNote is who they claim to be is only as strong as your trust in transport mechanism used to send the BlackNote (email, twitter, IRC, etc).
You can, however, be confident that the data you receive is exactly what the sender intended and no one else has viewed it.
