Previously, this site has introduced some of the EFS encryption and mentioned that there is no means to crack EFS encryption. On the past few days, a foreign software company claims that his software can already crack the EFS encrypted file. . Is this true, or the company picked up? Let's verify it together. This software is called Advanced EFS Data Recovery (unified here is AefSDR), you can download it here to the trial version, which can only decrypt the top 512 bytes of the file, and the registration software requires $ 99. In order to verify that Aefsdr is effective, I have made the following test: Windows XP Professional SP1 and Windows 2000 Pro installed on a computer.
