Open An Encrypted, Password Protected Saprsebundle Disk Image With iPhone?

Question

Is it possible to open an encrypted, password protected sparsebundle disk image using an iPhone/iPad/iPod Touch that is stored on a NAS drive connected to an AirPort Extreme Base Station?
If so, how do I do it?
If not, would you be able to explain why not?
Thanks, Alex

Hi Robert,

to have a regular user
   That's not really true. Sudo is one of the most flexible commands around and not only can a regular user use it but they can use it without a password. Mind you I'm not suggesting that you make all users admins; you can specify both of these privileges for this command only. All you have to do is to put a line like the following in your /etc/sudoers file. (with sudo visudo of course)
ALL ALL = NOPASSWD: /usr/bin/hdiutil create -encryption -certificate*-stdinpass -type SPARSE -fs "HFS+" -volname-size
I've included wildcards so that the cert file, volume name, size and image are arbitrary but the others must be in the user's command to qualify. I realize that you'll want different options to use FileVault certs but I don't know how to do that so I used your original example as my example.
   Of course it wouldn't be that easy for your lusers to get all of those options correct so the next thing you do is to wrap the command, with it's sudo preface, in a shell script that parses the cert file, volume name, size and image from the options the user passes to the script and puts those into the command with the right syntax. If you want to get really fancy, the script could prompt the user for any arguments that were omitted. Your lusers will think that you created this really cool command and never know that sudo was involved.
