With Google Keep Encryptor, you can easily keep your sensitive information only with you and your trustworthy friends. Your text will be encrypted into ciphertext with the help of Stanford Javascript Crypto Library .

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 titles of your encrypted notes.

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 (bookmark it).

• Android: You will need to install Kiwi Browser. Then install the Chrome extension
• iOS: You will need to install Userscripts Safari extension. Afterwards, you should be able to install the script when you open this link on Safari. Here is a nice tutorial of how to run Tampermonkey scripts on iOS.
