Available for Google Chrome and ChromeOS, miniLock provides a tool for encrypting all kind of files inside the Chrome browser. Portable, easy to use, it is a replacement for the venerable crypto program PGP.

Quoting from the conclusion report of Cure53 :
Cure53 was tasked to test against the application security of miniLock and evaluate its cryptographic properties and promises. Over the course of four days of manual testing, no severe errors have been spotted. The code is soundly and neatly written, well structured, minimal and therefore offers no sinks for direct exploitation.

Here's a user flow :
This section outlines an example user flow in order to help demonstrate how miniLock is supposed to help people.

Alice wants to send a scan of her passport to Bob. Sending it over email would compromise personal information, so Alice decided to first encrypt the scan using miniLock.

Bob opens miniLock and enters his email address and passphrase. miniLock displays his miniLock ID, which is tied to his passphrase and is persistent. He sends Alice his miniLock ID, which looks something like this: quBSaJLXKsRiaSrhgkPnswKocth711H29ZamMi1H9j4Mb

Alice drags and drops her passport scan into miniLock and enters Bob's miniLock ID as the recipient. She clicks the encrypt button and sends the resulting .minilock file to Bob. Once Bob drags the encrypted file into miniLock, it automatically detects it as a miniLock-encrypted file destined to Bob, and decrypts and saves the passport scan on his computer.
