EFS encryption algorithms in Vista RRS feed

  • Question



    I have the following problem with EFS.

    I use the same certificate since july 2000, and tested it on Windows 2000, 2003 Server, XP and different early builds of Windows Longhorn-Vista.

    But now, after installed Vista RC1 build, I can't access files from Windows XP or 2003 server, which have been encrypted in Vista. In the file properties it is shown that files were enypted with AES 256 bit using my certificate - but I still cannot access them in Windows XP.

    I suppose that encription algorithms were changed, but I found no technical documentation at all, and moreover cipher.exe says all files are encrypted using AES 256 bit, algorithm which is also used in Windows XP.

    Please, don't tell me about wrong certificate - this not the problem I experience. Can someone explain me what happened with EFS compatibility in Vista?
