Do you need to store sensible passwords in an cloud environmemt like EverNote, Confluence, DropBox, Dokuwiki?...
It seems secure until someone break security. And then your passwords are exposed.
This project is a chrome extension that encrypt your passwords using local resources or using a php code acting as a API.
Additionally, you can select the encrypted text and decrypt directly to the clipboard using the right button.
Personally, I recommend store passwords unencrypted in a local storage like keepass or a plane text field. This software comes with no warranty and his purpose is to add a securyty layer if you have to expose your sensible information like passwords in a cloud and more vulnerable site.
