Indexing encrypted files by impersonating users

A computer-implemented method for accessing content of an encrypted file by impersonating users associated with the encrypted file, the method comprising:

• determining that a file is encrypted;
• determining one or more keys associated with the encrypted file;
• associating the one or more keys with one or more users;
• receiving a determination that at least one of the one or more users is logged on;
• receiving logon information for the at least one of the one or more users determined to be logged on;
• and
• using the logon information, impersonating the at least one of the one or more users in order to access the encrypted file.

One or more computer-storage media having computer-executable instructions embodied thereon that, when executed, perform a method for indexing an encrypted file by impersonating a user associated with the encrypted file, the method comprising:

• initiating indexing of a directory containing a plurality of files;
• receiving an indication that one of the plurality of files in the directory is encrypted;
• determining one or more keys associated with the encrypted file;
• associating the one or more keys with one or more users;
• determining if at least one of the one or more users is logged on;
• and
• if it is determined that the at least one of the one or more users is logged on, impersonating a logged on user using a logon token handle associated with the logged on user,
• based on impersonating the logged on user, accessing the encrypted file, and
• indexing the encrypted file.
