is a portable encrypted message container. WhisperNote
is free to use, open source, free from app stores and compatible with most modern devices (computers, tablets, phones).more
is different to other message encryption software because everything you require is contained in the HTML file you are reading right now.
- 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).
