My script is designed to compress (UDZO) [and optionally encrypt] a
read-write (UDRW) or an uncompressed read-only (UDRO) disk image
file. It should ignore other disk image files. It should ignore any
encrypted disk image file. Here is the script to test that ...
try
"hdiutil imageinfo " & sourceImage & " -format"
set dmgInfo to (do shell script the result)
on error
-- notify user that format is not available
return
end try
if dmgInfo is not in {"UDRW", "UDRO"} then
-- notify user that input file is not right format
return
end if
If the dmg file is encrypted, the 'do shell script ...' shows a
dialog asking for the password. I see the illogic of this and simply
click Cancel. My users will probably be confused by this dialog. To
avoid the dialog, I need to be able to determine if the file is
encrypted WITHOUT reading the file. Or I need to be able to supress
the password dialog, if possible.
The 'hdiutil imageinfo ...' command, without '-format', does return
encryption status, but not until you enter the password via the dialog.
I've looked at the DiskImageMounter application. It's scriptable, but
no commands to handle encryption.
Any ideas? ... or am I screwed?
