Interestingly, you can get this on Windows if you have ActivePerl installed, using the Win32::File module.

The catch (apart from the fact that you'd like to do this from Linux) is that Win32::File doesn't seem to have a constant for "ENCRYPTED", but it does return the correct bit set...

grep FILE_ATTRIBUTE_ENCRYPTED *\*.h
Include/WinNT.h:#define FILE_ATTRIBUTE_ENCRYPTED            0x00004000
[download]

And running GetAttributes on an encrypted file yields:

C:\>perl -MWin32::File -e"Win32::File::GetAttributes('README.TXT',$x);
+ printf
 qq(%X\n),$x;map {printf qq(%-10s %08X\n),$_,&{'Win32::File::'.$_}} qw
+(ARCHIVE C
OMPRESSED DIRECTORY HIDDEN NORMAL OFFLINE READONLY SYSTEM TEMPORARY)"
6021
ARCHIVE    00000020
COMPRESSED 00000800
DIRECTORY  00000010
HIDDEN     00000002
NORMAL     00000080
OFFLINE    00001000
READONLY   00000001
SYSTEM     00000004
TEMPORARY  00000100

I realize that doesn't really help you from Linux, unless you set up an "isencrypted_d" service running on NT :)

If you're curious, the 0x2000 bit is "FILE_ATTRIBUTE_NOT_CONTENT_INDEXED"...
