.SH NAME
hashcracker \- GPU\-accelerated password cracker
.SH SYNOPSIS
.B hashcracker
[\fIOPTIONS\fR] [\fIPASSWORD\fR]
.SH DESCRIPTION
hashcracker is a GPU\-accelerated password cracker supporting 41 hash types.
It runs on Vulkan, Metal, and DirectX 12 via wgpu, requiring no CUDA or OpenCL
driver installation. Targets can be specified as raw hex hashes, prefixed
formats (e.g. \(la$1$salt$hash\(ra), or hashlist files.
