Creating an encrypted disk image in a shell script

[fluffels]

After jumping through quite a few hoops and filling a sparseimage, the backup script I’m creating needs to convert said sparseimage to a read only disk image, which is encrypted.

Currently, I have this:

[code]hdiutil convert -quiet $bkpath/$tempname -format UDRO -o $bkpath/$endname -encryption -passphrase $password[/code]

Obviously this isn’t ideal as -passphrase has been deprecated in favour of -stdinpass.

Thing is, my brain isn’t working well enough to actually make -sdinpass work. How would I go about passing the variable $password off as input to this line?

Hiya,

stdin can be passed through a pipe. so the following might do what you would like:
[code]
echo -n $password | hdiutil convert -quiet $bkpath/$tempname -format UDRO -o $bkpath/$endname -encryption -stdinpass
[/code]
the -n is important for echo because otherwise you will end up with a password having a newline character.
