Clear Cache, erase History permanently with NetShred X, the easy-to-use internet track eraser for Mac OS X that securely erases cached files your browser and email programs leave behind. NetShred X is the internet privacy software that is easy, fast and cleaner. Easy because it runs automatically - you dont have to remember to use it. Fast because it runs in the background - you dont have to wait for it. Cleaner because it will erase, not just delete all internet tracks for almost every browser and email program on Mac OS X.
Your web browser stores copies of the images and text that you see when on the internet. This information can be recovered by anyone with access to your computer. These internet tracks - browser cache, history, download cache, quicktime cache, favicons, cookies and email cache, trash, spam and junk mail - not only potentially compromise your privacy, they also take up a lot of disk space. Clearing your cache, throwing these files in the trash, or deleting them will not remove the file contents from the hard drive - it just removes the file name from the directory, leaving the data intact and recoverable. To dispose of these internet tracks, you need an internet track eraser to erase them so they cant be recovered.

Requirements: Mac OS X

Whats new in this version: Added support for Firefox 3, Camino 1.6, Omniweb 5.7, iCab 4.1, Opera 9.5, SeaMonkey 1.0

SubRosa Encryptor allows you to take files or folders and convert them to an encrypted secure, "Internet friendly" archive that can be stored on your computer or sent to a friend without worrying about prying eyes. Your personal stuff gets translated into a secure format using technology similar to that used with online banking (128 bit dynamic encryption with rolling keys, and stream encryption).

Subrosa Shredder allows you to securely erase files from your computer in a manner which makes it impossible for anyone to retrieve those files. Much like the common office shredder, it will take any documents you throw into it and turn them into pulp. Technically, this is achieved by writing an industry recognized secure pattern over the entire contents of the file, changing the relevant directory information, and then instructing the operating system to remove the remnants.
