Hashstack ™ is the ultimate password cracking software stack, designed and developed by the world's top password crackers for true password cracking professionals, and exclusively available on Terahash ® turn-key password cracking appliances.

Optimized Workflow

Modeled after Team Hashcat's own workflows, Hashstack ™ works the way you work and is designed with team collaboration at the forefront. Hashstack ™ is project-centric and list-centric rather than job-centric, which means that hash lists are logically organized by case/engagement. You may then add collaborators to each hash list, optionally organized into groups/teams, so that multiple simultaneous users may work together against multiple simultaneous hash lists. And Hashstack's ™ advanced, multi-dimensional queueing mechanism and job scheduler ensures that all resources are fairly shared across the cluster, with the option to assign job priorities and resource limits. So whether you work in law enforcement, military/defense, information security, security consulting, digital forensics, or litigation support, Hashstack ™ provides the perfect environment for collaborative, multi-user password cracking!

Extreme Performance

Unlike other software which only supports GPU acceleration for a small subset of available hash formats, Hashstack ™ has full GPU acceleration for ALL 375+ highly-optimized hash formats. Coupled with Terahash's ® finely-tuned appliances which deliver up to 35% more performance over other solutions using similar hardware, Hashstack ™ offers unparalleled hash cracking performance. And unlike other software that allows you to queue up a batch of multiple hashes/files but then works on them in serial – exahusting all attacks on one file before moving on to the next – Hashstack ™ works on multiple hashes in parallel, and on multiple jobs in parallel too, enabling you to find the most passwords in the least amount of time.

Infinitely Scalablity

One Terahash ® appliance is great – 20 Terahash ® appliances are better! Password cracking has exponential complexity, so there's literally no such thing as having "too many" cracking resources. But password cracking is also an embarassingly parallel problem, and thus Hashstack ™ was designed to be infinitely scalable – you can purchase and stack as many appliances as your budget permits, and Hashstack ™ will fully utilize all of them for distributing password cracking jobs. Contrary to popular belief, the biggest advantage to operating a cluster of multiple Terahash ® appliances is actually not the ability to utilize the raw compute power of all resources combined, but rather the ability to run many simultaneous jobs in parallel. Posting up 12 TH/s on NTLM is certainly impressive, but the ability to run 200 jobs in parallel is far more impressive and far more practical!
