Zip Password Recovery

  • Zip Password by is a feature-rich and flexible password recovery tool for ZIP, PKZip and WinZip (*.zip, *.zipx) archives.
  • It works with '.zip' (default and most common) as well as with '.zipx' (PBKDF2, SHA and AES based) encryption methods.
  • Password recovery basics are covered in Password Search FAQ.

Zip Password Recovery Features:

  • Several attacks can be configured and queued:
  • "Save passwords to a file" option to verify search settings or to generate a new wordlist, etc.
  • Highly optimized code (SSE, AVX, AVX2, AVX-512) guarantees best
  • Utilizes NVIDIA and AMD Graphics processing units with a high-performance methods.
  • Supports up to 64 simultaneous processing threads (multi-CPU, multi-GPU).
  • Audio, script or web address based post-search notification.
  • Windows 7 - Windows 10.

Password recovery speed:

.zip (most common and default encryption):
Password recovery speed is very high (tens of millions passwords per second), but affected by several factors, such as number and size of files, compression method used, etc.

Intel® Core™2 Duo
T7500 @ 2.20GHz
Intel® Core™ i3
2100 @ 3.10GHz
Intel® Core™ i3
4130 @ 3.40GHz
> 20 000 000 p/s > 40 000 000 p/s > 50 000 000 p/s

.zipx (AES-128, 192 and 256 bit encryption):
The protection methods are based on PBKDF2 and AES algorithms, thus recovery speed is limited, but we did our best to enhance this tool performance as well as recovery speed with some advanced methods. The final password recovery speed is equal to CPUspeed + GPU(1)speed + ... + GPU(N)speed.
For example .zipx (AES-128) password recovery speed on Intel i3 + AMD Radeon R9 270 = 51 000 + 670 000 = ~720 000 p/s (passwords per second).

Discrete GPUs
Compute units or stream multiprocessors (CU, SM, SMX, SMM) are the main building blocks of GPU calculation power, thus 32xCU GPU card is almost 2 times faster than 16xCU GPU card of the same family and architecture running on the same frequency.

For cards with compute capability sm_35 (Kepler 2.0) and above (Maxwell, Pascal, Volta) you can expect approximately 50,000 p/s per every SM running at 1000Mhz. Test results below are shown to be very close to this estimation.

GTX 470 (sm_20)
14xSM, 625 MHz
GT 640 (sm_35)
2xSMX, 1046 MHz
Tesla K80 (sm_37)
2x13xSMX, 876 MHz
Tesla V100 (sm_70)
80xSM, 1246 Mhz
+ 235 000 p/s + 135 000 p/s + 1 500 000 p/s + 5 000 000 p/s

AMD GPUs are very "password recovery friendly" and consistent with architecture change from VLIW5 to VLIW4 and now to GCN. You can expect approximately 35,000 p/s per every CU running at 1000Mhz.

HD 6770
10xCU, 850 Mhz
R9 270
20xCU, 925 MHz
RX 480
36xCU, 1266 MHz
+ 350 000 p/s + 650 000 p/s + 1 600 000 p/s

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 noticeably different from the data above.

Trial Version Limitations:

Trial version can be used to check format and hardware compatibility. It allows you to setup and test run any password search for up to 15 min per set. Recovered passwords are hidden behind the asterisks "***".
