Secure Enough is a simple application for saving small text files using a cipher. It can be used to keep low security passwords/notes from prying eyes. It was originally designed to help me keep track of the hundreds of passwords I have for different web sites and passwords for work. It syncs up with Google Docs, so I can access my passwords from any connected computer.
Secure Enough is not meant for storing sensitive information such as the launch code to ICBMs. There are many easy ways to get around its 'security', e.g., memory scanners and key loggers. However, it is probably secure enough for some kind of personal use - use your own discretion.

Secure Enough lets you save your password-encrypted text files on your Google Documents account.
To start using Secure Enough with Google, click on the "Google Docs Online" icon.
If this is your first time using Secure Enough, there will be no Secure Enough data files on your Google
Docs account, which means you need to create one.
