.dmg -- opening encrypted images in Windows

Ideally, I'd like to encrypt my entire hard drive in this MBP. I use Time Machine, though -- and my understanding is that FileVault (a) is exploitable, and (b) requires that users be logged out for backups to occur. Both of those are big problems for me.

Behind that, the easiest way to encrypt things that really, truly should be protected somehow is to use Disk Utility to create a protected image, or such is my assumption. From what I understand, a .dmg can be converted to ISO within Windows (or opened with 7-zip). Is it at all possible for an encrypted .dmg to be converted/opened under Windows?

I ask because I'm not convinced I won't be on a Windows 7 notebook at some point, especially with updated HP Envy and Sony Vaio models coming. Could be wrong, but I like flexibility.

(I know that TrueCrypt serves a similar function to encrypted .dmg files via Disk Utility and is cross-platform, but still.)

 

a dmg can be encrypted... an iso cannot. You can use a 3rd party tool to encrypt one.. then unencrypt it before using it.... but to convert an encrypted dmg over to iso, you have to remove the encryption. iso was never designed to be secure.

PowerISO (not free) is supposed to be able to handle .dmg files just fine on Windows.

 

Right, I understand. Do you happen to know if PowerISO -- or 7-zip -- can handle encrypted .dmg files under Windows?

 

this one is supposed to be able to do encrypted dmgs...

What I'd do though.. is make a test encrypted DMG, and test it on something you want, and check... like 7-zip

 

Thanks for the link -- looks useful. Just trying to keep options open in the event that I end up back on a Windows 7 notebook at some point; haven't yet confirmed that 7zip can, or can't, handle encrypted DMG files.

(ETA: This suggests that it can't, as expected.)

Don't currently have a Windows install with which to test, though. Removed my BC Win7 partition quite awhile back.

 

Not sure, but you can look into HFSexplorer, and macdrive to see if they have the ability to open encrypted disks in windows.
