Secret Keeper for Windows

Program used to securely store passwords, notes, documents, and credit card numbers. Data is stored encrypted on your hard drive, protected by a single master password.

It can be used to generate very strong, random passwords for your sites/accounts, any notes you do not want anybody to ever see, documents you want to keep secret (such as tax returns).

You can also export documents for use with secure emailing to other users of Secret Keeper.
