Private Note Link
Write a note, get a link that holds it encrypted. Nothing is stored anywhere.
Free tools that run in your browser. Nothing you type, open or create is uploaded to NerdBible or anyone else.
Someone sent you a private note. It is stored inside the link itself and is decrypted on this device when you press the button.
This is not a self-destructing note. Nothing is stored on any server, so there is nothing to delete: the encrypted note and its key both travel inside the link. Anyone who has the link can open it, as often as they like, for as long as the link exists in a chat, an email or someone's browser history. For extra protection tick the password option and give the password by a different route, such as a phone call.
How to use it
- Type your note, up to 4,000 characters.
- Optionally tick Also require a password and choose one.
- Press Create link and send the link to the person. Send the password, if you set one, some other way.
- They open the link, press Reveal note and read it on their own device.
Questions
Can NerdBible read my note?
No. The note is encrypted in your browser with AES-256-GCM and a random key. The key sits after the # in the link, and browsers never send that part of an address to the website. When the page opens a link, it also removes that part from the address bar before any analytics could see it.
Does the note delete itself after reading?
No, and the page does not pretend to. Since nothing is stored on a server, there is no copy to delete. The note lasts as long as the link does, so treat the link like the note itself.
What does the password add?
Without a password, the link alone opens the note. With one, the note is encrypted a second time with a key made from the password (PBKDF2, 600,000 rounds), so someone who finds the link in a chat history still cannot read it.
Why is the link so long?
Because the whole note is in it, encrypted. A longer note makes a longer link. Some apps shorten or break very long links, so keep notes brief.
