Configuring certification authorities to deliver EFS certificates to users as part of your public key infrastructure simplifies the manageability of recovery agents. EFS automatically obtains the recovery agent’s public key for file recovery from the recovery agent’s X.509 version 3 certificate, which is stored in the EFS recovery policy.

Otherwise, encrypted files are stored as plaintext and encrypted folders lose the encryption attribute. If no profile can be located, EFS creates one for the user. The cipher utility can be called in a logon script to automatically and invisibly migrate users. EFS writes the encrypted data, along with the DDF and the DRF, back to the file.

Figure 18-3 illustrates the process of obtaining an FEK to encrypt the data and obtaining public keys to encrypt the FEK, and it shows the structure of the encrypted file. That should do the trick.
