Hashcat
Hashcat is a high-performance hash cracking software and OpenCL compute application used to recover plain-text passwords from hashed data. It functions as a GPU-accelerated recovery tool and distributed password cracker, leveraging CPUs and GPUs to perform intensive cryptographic computations.
The system differentiates itself through a distributed cracking workflow that coordinates tasks across multiple machines via an overlay network to share computational load. It further optimizes recovery speed using Markov chain keyspace optimization to prioritize the most likely password candidates.
The software supports multiple attack modes, including mask-based brute force and dictionary-based recovery. It includes hardware performance tuning, hash algorithm benchmarking, and a thermal watchdog for hardware health monitoring. Long-running operations are supported by session management for pausing and restoring progress.
Containerized deployment options are available to simplify installation and runtime configuration across different platforms.
