Professional Data Security (PDS) for Mac

From Everything Penguin:

Have you ever needed to enter a username and passphrase, but you didn't have it with you? Do you store your authentication credentials on a unprotected thumb drive, or worse, on a piece of paper in your pocket? Would you like the ability to encrypt multiple large files simultaneously, writing them to disk *OR* tape, with a very small memory footprint? If you answered yes to any of these, this application can help. Many of us need anywhere/anytime access to our "private" data. More importantly we need to ensure that the access and our data are secure. The goal of this application is to deliver an easy and intuitive tool to provide secure anywhere/anytime access to your data, allowing you to carry sensitive information (account numbers, login credentials, etc.) on your thumb drive without worrying that your data will be compromised should the thumb drive be lost. In addition, this application can also encrypt any existing files you may have, keeping them protected as well. This application was designed to be installed to and executed from a thumb drive; a thumb drive that can be plugged in to any Java enabled computer. As an enhancement, the application is also delivered via JNLP (Java Web Start) to add a few additional features (desktop icon, control panel configuration, etc.) that we have come to expect. Using either mode of installation, this application will encrypt your data, rendering it useless to anyone that does not have the encryption key. In addition, the application provides configuration options that allows full interoperability among different installations; a file encrypted "on the road" using the using the thumb drive installation can be decrypted on another machine that has the JNLP installation. PDS provides a multi-window editor for your files. To open a file, select it and provide the passphrase. Files can be opened in read-only (view) mode or read-write (edit) mode. The encryption key protecting your data is kept a KeyStore, and both the key and the KeyStore are protected by passphrases. Without the correct credentials, the key remains secured and your data cannot be decrypted. In addition to the ability to securely view and edit PDS files, this application also provides the ability to encrypt and decrypt your existing files. If you use this application, a single passphrase can protect all your sensitive digital information. Or, if you prefer more than one passphrase, each file could be protected by up to two unique passphrases.
