A free online notepad is called Publicnote. To start a new note or access an existing note, enter any title. Publicnote can be used without creating an account.
As you type, all notes are automatically stored to the cloud. The success of a note’s saving is shown by the check mark in the upper right corner.
Each note is AES-256 encrypted, with the title serving as the encryption key. The encrypted message is then index in a database using the title’s SHA-256 hash. The title is never revealed because SHA-256 is a one-way function and the process happens in your browser; as a result, neither the website owner nor the web host (AWS) can access the plaintext contents of any note (unless the note is encrypted).
