How to Obtain Microsoft Support Files from Online Services
There are two files in the patch package, a new version of Psbase.dll, the software module that performs encryption and decryption of the Protected Store and a tool, Keymigrt.exe, which decrypts and re-encrypts all items currently in the Protected Store. While the patch ensures that any future data added to the Protected Store is encrypted using the strongest cryptography available, it cannot upgrade the protection on items that already exist. The Keymigrt tool is used for this function. It decrypts what is already in the Protected Store, and then re-encrypts it using stronger cryptography. This is also true for the Service Pack. The service pack provides the patch but does not re-encrypt the Protected Store. To do this you need to download the hotfix, extract the files and run the keymigrt.exe tool. The tool is not extracted when you install the hotfix. To extract the tool, run the hotfix package using the -x option. This causes the patch files to be extracted into a folder of your choice. Keymigrt.exe is one of the files in the patch. Please remember that the -x option does not install the patch. NOTE: The tool cannot be run unless the patch has already been installed. On any post-Service Pack 1 (SP1) Windows 2000-based computer, you do not have to run the Keymigrt.exe tool if:
