You may also want or need to know that WinZip encryption and several other ZIP, file, folder and full disk encryption implementations are not FIPS-140-2 certified.
WinZip's AES implementation is FIPS-197 certified by NIST, however FIPS-140-2 certification (which is given in assurance levels 1, 2 or 3) considers more than just the specific encryption cipher as implemented in code.
You may need or want FIPS-140-2 certification, such as in cases where you wish to achieve HITECH Act "Safe Harbor" from EPHI disclosure notification requirements or if you need to meet DOD or FISMA C&A requirements for a particular government agency grant or contract.

it should be noted that you can typically peruse the directory structure and view all file names within a password protected zip archive without having the password. in some cases, that may be unacceptable data leakage.best, alex Alex Keller Systems Administrator Academic Technology, San Francisco State University Office: Burk Hall 153 Phone: (415)338-6117 Email: alkeller () sfsu edu On 6/11/2010 9:10 AM, Adam Nave wrote:7-zip gets a lot simpler if you use the right-click menus.

Otherwise your users will be fumbling with multiple versions of the same zipped file, overwriting each other's work and generally being confused. There is a learning curve to TrueCrypt, but if you set it up correctly to start (automouting the folder for instance), then it won't be too bad.--Adam
