The password in question unlocks these files from the protection of locally stored AES-256 encrypted disk image. A location where an 'email me a password reset link' is not an option. Encrypted the same way with the same password. Password paper backup? I'll get to that. I somehow needed to 'crack' this. Decrypting the disk image This is the easy part, on Mac and Windows and many Linux Desktops: Simply double-click and you will be presented with a box asking for a password. I enabled the full disk encryption or at least I think so. The HD shows up as 'Encrypted Logical Partition' in Disk Utility. When I boot up the macbook however I can choose between logging in as Andreas Bonini - with my user account password - or entering the disk password. If I choose the former option, I am never asked for the disk password.

What is DMG file
A DMG File stands for Disk Image file and it is a file format which is used to create mountable disks on the Macintosh operating system. The DMG File format contains data in the form of blocks which are often secured using encryption methods or are compressed using compression algorithms. DMG files are used for installing tools and softwares into the Mac OS operating system. The file is downloaded from the internet from the software manufacturer's website and upon mounting the DMG file, a virtual disk is generated from where the user can either copy the application to the applications folder or run an installation script depending on the type of installation.
The newer disk image file was used in place of the original IMG or image file which was used in earlier versions of mac that are classic mac operating systems. Disk Image Files are only meant to be used in Mac based systems and not on the Windows operating systems. However, using some image softwares like Daemon tools on windows, we can mount disk images of DMG type on windows too. Some tools can also convert DMG Files to windows-recognizable image files like .ISO files.
Benefits of DMG Disk Image format
- DMG Images are read only which ensures that the files inside the installer are not altered with. This makes the software supplied inside the dmg secure from viruses as no one can alter the file after it is created.
- Instead of sending more than one file over the internet, the creators have to send a single dmg disk image which contains all the required installation files of the software that can be simply dragged and dropped into the applications folder of Mac to install them.
- DMG files can be customized according to the manufacturer's wish so that the installers look pleasing when people download the files for installing software.
- Disk images can be mounted on a computer just like a physical cd. This is a good thing as people can save a copy of the DMG file as a backup which can be used later to restore the previous state of the files.
What is ISO File
-Step-7.jpg "Disk image .dmg does not ask for password when encrypted file")
An ISO file stands for International Organization for Standardization file format which specified ISO as the standard file format for disk image files in Windows. It is a file which can be used to mount disk image files in Windows operating systems. It can be used to emulate a CD, DVD or any other disk drive in Windows virtually.
It is generally used to hold disk images of operating systems like linux which can be burned into a disk or a USB drive. It is also used to send installation files of Windows softwares through the internet but they are usually sent through a binary package with an executable or an msi installer.
Basically ISO files are an image of something so you could have an image of a computer software package that would be all the files that existed on that computer software in one finite image. You can also burn that image file to a CD because these are optical images.
How to Convert DMG File to ISO
The ISO file format can be used on the Macintosh operating systems, however, almost all of the software packages for Mac is downloaded from the internet as a DMG Disk Image file. Although the DMG file format has some features which are not available in the ISO format like file encryption methods and compression algorithms, DMG files cannot be used anywhere else instead of a Mac. This is why we may need to convert DMG FIles to the ISO File format.
To convert dmg to iso file on Windows, you should install third party softwares like PowerISO. It is a disk image burning software that can be used to convert DMG File to ISO on Windows. You can also directly burn DMG Files to a CD/DVD using this software.
Before downloading PowerISO, check the system requirements that is required to install and run Power ISO.
System Requirements
- Any one of the following Windows Operating systems: Windows 98 / Windows Me/ Windows NT 4.0 / Windows 2000 / Windows XP / Windows 2003 / Windows Vista / Window 7 / Windows 8 / Windows 10 operating system or above.
- PowerISO can be used in both 32-bit and 64-bit versions of windows.
- Processor: Intel Pentium with 166 MHz clock speed or better.
- 64 Megabytes of RAM.
- A minimum of 128 Gigabytes of storage space is required to install and run PowerISO.
Steps to download PowerISO on Windows
- Visit the official website of the PowerISO.
- Go to the download section of the website
- Select the version 32 bit / 64 bit according to your computer.
- Click on download PowerISO 64 /32 bit
Now, an installer file will be downloaded on your computer, open the file and do the required steps to install PowerISO on your computer.
To convert DMG to ISO, first open the PowerISO application on Windows and then select the tools option from the top ribbon.
From the dropdown list, select the option labeled as convert. Now you will see a dialog box titled convert image file. You can use this to convert image files from one file format to another. In our case, we have to convert it from dmg file format to iso file format so we will set it up accordingly.
Now, we have to select a source image which will be your dmg file you want to convert. After that, select the destination image file and name it as the name of the iso file you want at the end. Below that, there is a drop down menu where you have to select the output file format, select iso file format there.
After that, there are image file settings options where you can password protect the images but since we are converting dmg file to iso, iso doesn't have password protection options so that section is greyed out.
Now, select OK to start the conversion process. Wait for a few minutes for the conversion to complete. When the conversion is complete, you should get a message which says 'Converting image file completes successfully'. If there is an error, check whether the input dmg file is corrupted or not. If there are no errors, go to the location of the output file you specified earlier, you should have an iso output file of the name you have given.
I like to tinker with encryption, not because I have any real use-case for it, but because I find the entire subject enjoyable.
Just thought I'd take a moment to share with you the bit I was working on tonight: A symmetric (passphrase) encrypted disk image usable on Mac, Linux, and Windows.
WARNING: I am in no way responsible if you do something to break your data or your computer. Make sure passphrases you use are accurate and you can remember them, there is no way to recover an encrypted file without them.
First up: Create the disk image, I chose ExFAT as the filesystem as it is reasonably portable and standardized on as the filesystem for SDCards means out of the box support on most systems (including Raspberry Pi). I'm using .dmg as the file extension because Mac requires it on creation. Feel free to use whatever suits you.

On Mac you can double-click the file, or type open or open disk utility and use file -> open. On Linux you may be able to double-click in some desktop applications, but you can always mount it with mount -t exfat -o loop
Encrypting the disk image
I use GPG Keychain on Mac, which allows me to simply right click the file and then use Services -> OpenPGP: Encrypt File and then uncheck any keys in the main section and check the Encrypt with password box in the lower left.
The commandline option will work under Mac or Linux with GPG installed. I'll do an article on getting GPG installed at some point in the future and try to remember to link it in here.
This will prompt you to enter a passphrase, which will be converted to an appropriately sized key. The -s is optional, it will also sign it with your private key so that it can be verified during decryption. If you get the following error, you don't have a private key set up for signing and can not use -s.
On Windows… right click and hope your GUI has an encrypt function? I've got a Windows computer around here somewhere… I'll try to figure it out later.

Once encrypted you can share it as needed. Depending on your goal you may want to additionally delete the original (non-encrypted file) after you've done some verification. How much verification you do will depend on how paranoid you are, this is a good step, though gpg -d encrypted-file.gpg | cmp - original-file.dmg
Decrypting the disk image
This is the easy part, on Mac and Windows and many Linux Desktops: Simply double-click and you will be presented with a box asking for a password. After decryption is complete, if you signed the file with -s, it will pop up a notice telling you that the signature has been verified and you know that the contents were extracted correctly.
The command line method is:
If all goes well you'll get output like:
Descargar imgburn download freeclubsoftsoftram. You can now mount the disk image just like in the Creating the Disk Image section.
Final Words
These encryption and decryption instructions will also work with any individual file. For small files you can even do fun things like not use --armor instead of -o and get output to the terminal in ASCII text, suitable for including in e-mail or the like.

However, I really actually recommend just encrypting the files with your own key as a recipient in general. As long as you have your private key, then you can access the disk image, file, or whatever. If you are sending the file to someone else you should encrypt it using their public key as the recipient so that they can easily decrypt it. Symmetric encryption is for the times that you are encrypting it for your own use in a case where you will have access to GPG, but potentially not to your own private key.
