Zip password unlocker with GPU acceleration

Under the hood of Accent ZIP Password Recovery there is a highly optimized source code. It drives and boosts the program to the highest possible speed of password searching on any Intel or AMD system. That is what makes the program stand out of the crowd of similar solutions on the market.

And the top benefit is soaring acceleration on graphics cards:

Performance comparison of brute force search – CPU vs. single GPU

AccentZPR accelerates on all NVIDIA and AMD graphics cards that have appeared in the last ten years. Depending on characteristics of the CPU in the system, number and performance of GPUs, the Zip password unlocker can run dozens times faster (see GPU rating).

Please note: in the demo version there is no limit to the speed of brute force, while only one GPU device is supported.

Improved password attacks

By means of flexible range customization option Accent ZIP Password Recovery additionally reduces the time to search for Zip/WinZip passwords thus cutting of unnecessary checks and unlocking Zip passwords much faster.

Here is what is cool about AccentZPR:

Brute force with extended (position) mask

The program lets you assign a character set individually for each position in the generated password and get rid of unnecessary checks. This works effectively when you know the password structure.

For example, you known that the password begins and ends with a digit, the length of middle part is unknown, all you know it contains only capitalized vowels, and there is an arithmetic character in the last-but-one position.

AccentZPR allows you to define such criteria in a mask, and then generate password while checking only those meeting the defined criteria:

+ the number of passwords to be tested and time spent is dramatically reduced

the method requires have at least a rough idea of the password structure

Dictionary attack with customizable mutations

Accent ZIP Password Recovery supports simultaneous working with up to 4 dictionaries: merge words from various dictionaries, change characters in generated passwords, replace characters etc. Over 20 mutations supported.

For example, you known the password is a combination of words, all the letters of which could be either uppercase or lowercase; leet-spelling could be used.

All these criteria can be defined with the visual «Rules Editor» of AccentZPR. Then passwords are generated based the specified rules:

+ the number of combinations to be tested extends as much as needed for successful unlocking of a zip password

the method requires you to have at least a rough idea of the password phrase

Same old attacks at higher speed

Of course, AccentZPR features a "classic" set of attacks to crack totally unknown Zip passwords: brute force, mask attack and dictionary attack:

Password attacks in Passcovery programs

All the attacks can be used both individually and as part of multi-phase password search scenarios. In the latter case, the program sequentially, phase by phase, performs all the attacks specified in the scenario. AccentZPR lets you choose a ready-made script for unlocking Zip passwords or create a script of your own with the required complexity.

See detailed instructions on how to create attack scenarios in the help file.
