Security
- WhisperNote uses AES 256 bit encryption to store your data, this is a very strong form of encryption.
- WhisperNote uses your browser as the execution environment, you probably use your browser for your banking too.
- WhisperNote does not store your data on a server, it saves it to the device you are using.
- If you lose your password, it cannot be recovered.
- Providing high quality security tools is very difficult and like other tools WhisperNote has known weaknesses.
- For more information please see the website.
Create your note
- Just type or cut and paste the text content you want to encrypt in the Message area.
- You can optionally select a single file from your device to be included with your note. This file should be less than 10Mb in size.
- Once you're done editing your note, at the bottom of the screen type in a password to protect the note contents.
- Optionally, provide a hint for yourself, but don't make it obvious.
- Hit the Encrypt button. This will encrypt the note and package everything neatly into a single HTML file. You can save it to your local disc or perhaps a cloud service.
Share your note
- Due to technical limitations of current browsers, if you send a WhisperNote through email (or other insecure channel) the recipient needs do one of three things to read it securely:
- Download a new WhisperNote and Import your note into theirs.
- Use the Consunet Validator service to check that the note has not been maliciously modified in transit.
- Temporarily disconnect from the Internet when they are reading the note.
- When sharing the password you should use a different channel to the one you sent your note through (i.e. call the recipient over the phone).
