subnotes

Simple, secure, encrypted, zero-knowledge note-taking application. Key features:

  • no database - everything is stored in a single encrypted vault file on a server
  • no metadata - as the folder structure is faux and recreated from an array of objects in javascript, there are absolutely no data stored, nor exposed on transmission
  • password never touches the server - even for the authentication, raw password is washed in hundreds salted rounds, one output is checked against the server, the other separate output is used to decrypt the vault
  • tamper-proof - no need to trust even your neighbour, as no sensitive data leaves the client, you can let a friend install subnotes on their server for you and then compare checksum of javascript files loaded in your browser from said server with the ones in this github repo. This way, security is guaranteed regardless of location

Install

Simply copy this repository on your PHP server and access its URL from the browser. No plugins required. You will choose your password on the first opening as it recognises no hash generated on the server. The installation is very small, but you can go even further and minify the content of data/ if you need. Timestamps in the listing are using czech locale/format. You can change this to english or any other format in data/do.js on line 54 in toLocaleDateString('cs', options) to yours.

Future & what am I working on

[ ] - change password option (requires reencrypting the vault) [ ] - ability of a user to change the order of displayed notes [ ] - keyboard shortcuts from common text editors [ ] - backlinking from other notes & displaying what notes link to selected one
