DMG Password Recovery

DMG Password by is a feature-rich and highly-optimized password recovery tool for OS X and macOS Disk Image files ('.dmg', '.sparseimage'). Both 128 and 256 bit AES encryption methods are supported. DMG Password is designed for MS Windows. Please use trial version to test compatibility layers and virtual machines on other platforms.

Disk Image password protection:

.dmg and .sparseimage disk image files password protection is based on PBKDF2 key derivation function and AES-128 or AES-256 encryption algorithms. Passwords are hashed with thousands of iterations, thus recovery speed is limited, but we did our best to enhance this tool performance (recovery speed) with some advanced methods. DMG Password allows you to setup a very precise search range to exploit known password details (parts and patterns) and reduce the search time required in comparison to traditional attacks. Just check mixed attacks for example.You may also check Password Search FAQ.

Password Recovery Speed:

Disk Image encryption complexity (number of hash iterations) is variable from file to file (from 1000 upto 300 000). The following tables are based on .dmg files with 100 000 iterations.
The final password recovery speed is equal to CPUspeed + GPU(1)speed + ... + GPU(N)speed.
For example: Intel Core i3 + AMD R9 270 = 250 + 3500 = ~3750 p/s.

AMD and Nvidia GPUs
Compute units or stream multiprocessors (CU, SM, SMX, SMM) are the main building blocks of GPU calculation power, thus 32xCU GPU card is usually twice as fast as 16xCU GPU card of the same family and architecture running at the same frequency.
You can expect approximately 300-400 p/s performance per every Nvidia SM running at 1Ghz and approximately 150-200 p/s per every AMD CU.

It is important to mention that AMD and NVIDIA architectures are quite different and although AMD per CU performance is lower, there are more CUs per card in a similar price range. Moreover GPU performance is somewhat variable with number of factors including GPU/CPU combination and even a driver version. Please contact us if your recovery speed is noticeable different from the data above.

Trial Version Limitations:

Trial version is available to check format and hardware compatibility. It allows you to setup and test run any password search for up to 15 min per run. Recovered passwords are hidden behind the asterisks.
