I don’t know about you, but I still haven’t got over the death of TrueCrypt. It was a fantastic program for making encrypted folders in all respects, and its demise was totally unexpected.
The first is Disk Utility, which is primarily intended as a disk repair and imaging utility. But it can also be used to create a disk image that contains a folder’s worth of encrypted files. Likewise, Print to PDF is a way to create a standard-format file that you can send to people on any OS. Create An Encrypted DMG. Any user with admin rights on the computer can change the permissions on a file. More importantly, anyone can take the disk and connect it to a different machine and change the permissions. Encrypted files are different. The only way to access an encrypted file is with the password.
The reason it’s so slow is because your AES256-encrypted DMG uses 250,000 rounds of PBKDF2-HMAC-SHA-1 to generate the encryption key. The ludicrous round count makes it extremely computationally expensive, slowing down the HMAC-SHA1 process by a factor of 250,000.

Examview download mac. Now I know that it has a successor – VeraCrypt – and it is more or less twin siblings. But VeraCrypt still doesn’t feel the same. And I have had lots of issues opening encrypted folders using VeraCrypt, and losing valuable files in the process.
But if you use a MacOS computer, then you don’t need VeraCrypt, because Disk Utility will make your encrypted folders for you.
Encrypted Folders With MacOS Disk Utility
It wasn’t that long ago that I showed you how to format a USB stick or SD card using Disk Utility. Many MacOS users routinely overlook Disk Utility, but it is really a nifty little program. The encryption abilities is just the icing on the cake.
An encrypted folder on MacOS has the file format DMG (similar to many MacOS software installation programs). DMG stands for “Disk Image”, and is not much different than an ISO file on Windows. Once the DMG folder has been created, you simply “mount” it to open it, and you can start dragging items in.
The process to make an encrypted DMG folder is absurdly simple.
Open Up Disk Utility
Obviously you are not going to get very far without opening Disk Utility! You will find it in the “Utilities” sub-folder of the “Applications” folder. It doesn’t matter which area of the computer is currently highlighted. When it comes time to make the disk image, you will be asked where you want to save it.
Start a New Blank Image
Go to the Menu bar and choose File–>New Image–>Blank Image.
Start Filling Out The Details Of The Encrypted Folder
Here is where you set up and configure the container to your specifications. Let’s go through each one.
Choose Your Encryption Protocol
When you drop down the Encryption menu, you are given 2 options. 128-bit AES encryption, and 256-bit AES encryption.
Essentially, both are extremely secure, but the 256-bit version is more secure than the 128-bit version. The only downside (as the menu says) is that if you encrypt with 256-bit, you are going to see a noticeable time-lag.
However, unless you are hiding Top Secret files, or running Wikileaks from your MacOS computer, then the 128-bit version will be more than sufficient.
Set The PasswordEncrypted Dmg File
When you choose the encryption standard that you want, it will immediately ask you to set a password. Obviously it goes without saying to choose an extremely strong password. No dictionary words. Instead, a combination of letters and numbers.
If you can’t think of one yourself, you can make it easier on yourself, by clicking the key icon, and a Password Assistant will open up. Next to “Length“, slide the slider along to the number of characters you want. Under “Type”, choose which kind of password you want. As I said, the letters and numbers one is the most secure, but ultimately it is up to you.
It will then show you a password you can use under “Suggestion”, and under “Quality”, the green bar will tell you how secure it thinks the password is. If for some reason you don’t like that password suggestion, drop the menu down, and you will get lots more suggestions.
Choose one, then copy and paste the password into a secure document. If you lose the password, you lose access to the disk image!
Wait For The Encrypted Container To Be Made
When you have filled in all of the details, and you have clicked “Save”, it will create the disk image folder for you. When it has been made, click “Done”….and you are done.
![]()
Go to the Finder location where you told it to save the disk image, and it will be sitting there open waiting for you. To access it, go to the folder name in “Devices”.
Double-Click To Mount & Open The Folder
To normally open the folder (such as when it is closed), double-click the DMG file and a window will jump up, demanding the password. It should be noted at this point that you cannot copy and paste passwords into the box. You need to type them manually.
For obvious reasons, you do not want to have checked “Remember password in my keychain“. Otherwise, when you put the mouse cursor inside the password box, the password will automatically be entered!
Kind of defeats the whole purpose of encryption doesn’t it?
Drag Your Files Inside The New Window
Once you have successfully entered the password, the folder will appear in the Devices section. Click on it to enter the folder. You can now view the contents, delete files from the folder, and add new files.
When you want to close the encrypted disk image folder again, click the upwards arrow icon next to the folder name. https://kzcqxw.weebly.com/ygopro-2-download-mac.html. This will dismount the folder and close it.
Conclusion
TrueCrypt and VeraCrypt may have its legions of fans (and I was one of them). But MacOS (and Windows, for that matter) have their own built in encryption tools. You just have to know where to look.

Backup Firmware Image
- Start iTunes on your computer, and then connect your iPhone to your computer using its sync cable.
- Click the button for your device near the upper-right corner of the iTunes screen, and then click the 'Summary' tab if it isn't already selected.
- Select 'This Computer' in the Backups section, and then click 'Back Up Now.' ITunes backs up your entire iPhone, including iOS, to the hard drive.
- Confirm that the backup was successful by selecting 'Preferences' from the main iTunes menu, clicking the 'Devices' tab, and then making sure that the time and date next to your iPhone's entry correspond to when you finished the backup.
- Disconnect your iPhone from your computer.
Decrypting with ipsw_decrypt.py
-
Run the
ipsw_decrypt.py
script on the firmware you downloaded or backed up.The output should look like this: -
Go into the
iPhone 4, 5.1 (9B176)
folder or whatever folder was created depending on the firmware you chose. -
Open the biggest file ending with
.decrypted.dmg
in order to mount the disk image. In this example:038-1768-165.decrypted.dmg
-
Run iOS Artwork Extractor. If the mounted iOS firmware version matches your simulator version, then you will discover much more artwork.
