Google Keep Encryptor Extension

With Google Keep Encryptor, you can easily keep your sensitive information on Google Keep only with you and/or share it with your trustworthy friends. Your text will be encrypted as ciphertext with Stanford Javascript Crypto Library (http://bitwiseshiftleft.github.io/sjcl/).

> SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes. Just as importantly, the default parameters are sensible: SJCL strengthens your passwords by a factor of 1000 and salts them to protect against rainbow tables, and it authenticates every message it sends to prevent it from being modified.

**WARNING**: If you don't remember the password, you will lose all the information on that encrypted note!!!** It's strongly recommended to use password hints as labels or add them to the title of your encrypted notes.

Android and iOS:
Currently the Chrome mobile app doesn't support extensions. In order to decrypt your notes, you have to install the Tampermonkey script on your phone and use the Google Keep website on mobile browsers. Further information can be found at https://github.com/Naiqus/Google-Keep-Encryptor/blob/master/README.md

Artur Santos (ID: 00000007bfc5e793) Voted 1 ★ - Updated 10/15/2023 Lost info when unlocked. It was keep encrypted.

Astro Biological (ID: 0000002649027a39) Voted 3 ★ - Updated 03/09/2022 Um.. question. The encrytpion works great. UInfortunately notes are also encrypted when I go in through other devices. I probably should have thought of that. Is there any way to decrypt this stuff on another device?

Orch 1 (ID: 000000bf25bf0172) Voted 2 ★ - Updated 01/13/2022 It is the first method I can see on keep to password notes. Thank you. Unfortunately this is very dangerous to use. If you change the code (type there something), all is gone. Also this is unusable on android phone and if you change the code, all is gone. If you have sensitive information's, probably you also don't want to loose them...

Michael (ID: 00000004785173a6) Voted 4 ★ - Updated 10/31/2020 This is fantastic!...When it works. Could you please update the app to fix the following issue? I've noticed that the extensions lock icon will show up on any note I click on a freshly loaded page, but I can maybe encrypt one or two notes before having to: A. Refresh the page. B. Switch from dark mode to normal mode (or vice versa). C. Switch to a different Keep label, then back to the label I was on (most convenient option). This is because after encrypting a note or two the lock icon straight up disappears and I have to do one of the above methods to refresh the page, then the lock icon shows back up again. For reference, I'm using the latest version of Google Chrome (Version 86.0.4240.111) and I do use a VPN extension, as well as uBlock Origin. I disabled both of those and refreshed the page just to see if they were causing problems and the issue still persists. This extension is excellent, but a quality of life update would really go a long way. Once you've encrypted your notes, then it's not really a big deal for new notes (assuming you're encrypting each note that needs it), but this is obviously really inconvenient when you either have a lot of notes to encrypt or you're creating several new notes at a time. Otherwise, excellent!
