recently released version 2.0 of their encryption and password protection utility
CipherDisk. The new edition allows you to burn password-protected and encrypted CDs and DVDs as well as create disk images. It also features a streamlined interface that provides access to all features within a couple clicks, according to the company, and it adds Advanced Encryption Standard (AES) to the available encryption methods.
CipherDisk allows you to encrypt and password protect any hard drive, CD, DVD, or other storage medium. It’s hidden until you scan your Mac with the utility and pull up the password window. With the newly added ability to create disk images, you can use CipherDisk to build a disk image with a predetermined size, or a custom one that dynamically grows as you add data to it, and password protect and encrypt it too.
Available encryption methods are: Exclusive bitwise-or (XOR), which is the fastest, but weakest, method provided; Tiny Encryption Algorithm (TEA), a 128-bit method that is more robust than XOR; SubRosaSoft, a proprietary method that balances speed and security; BlowFish, a 448-bit method developed by a leading security expert; and 128- and 256-bit versions of AES, which are widely used in cryptography circles.
This upgrade is free to all version 1 owners. The price for the full version is US$59.95.
