Update default hash settings to 64MiB:3:4 for Argon2 in -m 70000, following RFC 9106 recommendations.
Add option OPTS_TYPE_THREAD_MULTI_DISABLE: allows plugin developers to disable scaling the password candidate batch size based on device thread count. This can be useful for super slow hash algorithms that utilize threads differently, e.g., when the algorithm allows parallelization. Note: thread count for the device can still be set normally.
Add options OPTI_TYPE_SLOW_HASH_DIMY_INIT/LOOP/COMP: enable 2D launches for slow hash init/loop/comp kernel with dimensions X and Y. The Y value must be set via salt->salt_dimy attribute.
Change autotune kernel-loops start value to the lowest multiple of the target hash iteration count, if kernel_loops_min permits.
Fixed a bug in autotune where kernel_threads_max was not respected during initial init and loop-prepare kernel runs.
shuffle() present in some OpenCL runtimes
- Updated autotune logic: if the best kernel-loop is not yet found and
the current kernel-loops setting resulting in a kernel runtime which
is already above a certain threshold, do not skip to kernel-threads
or kernel-accel section if no variance is possible
- Revised all plugin module_unstable_warning() checks for
AMD Radeon Pro W5700X GPU on Metal: rechecked with the latest
Metal version and removed those now fixed
- Inform the user on startup when backend runtimes and devices are
initialized
- Fixed some file permissions in the tools/ folder
Improved autotuner tweak logic and added boundary checks for accel and threads
Fixed available host memory detection on Windows
Fixed compilation error in MSYS2 native shell
Introduced an 8 GiB host memory usage limit per GPU, even if more is available
Replaced fixed-size host memory detection per GPU with a dynamic kernel-accel based method (similar to GPU memory detection)
Disabled hash-mode autodetection in the python bridge
Removed default invocation of 'rocm-smi' in 'benchmark_deep.pl' to avoid skewed initial results
Reduced default runtime in 'benchmark_deep.pl' scripts due to improved benchmark accuracy in hashcat in general
Fix the automatic reduction of the kernel-accel maximum based on available memory per device by accounting for the additional size needed to handle register spilling.
Fix the tools/benchmark_deep.pl script to recognize benchmark masks more reliably.
Refactored inc_hash_scrypt.cl almost completely and improved macro names in inc_hash_scrypt.h. Adapted all existing SCRYPT-based plugins to the new standard. If you have custom SCRYPT based plugins use hash-mode 8900 as reference.
Fixed some compiler warnings in inc_platform.cl.
Cleaned up code paths in inc_vendor.h for finding values for HC_ATTR_SEQ and DECLSPEC.
Removed option --device-as-default-execution-space from nvrtc for hiprtc compatibility. As a result, added __device__ back to DECLSPEC.
Removed option --restrict from nvrtc compile options since we actually alias some buffers.
Added --gpu-max-threads-per-block to hiprtc options.
Added -D MAX_THREADS_PER_BLOCK to OpenCL options (currently unused).
Removed all OPTS_TYPE_MP_MULTI_DISABLE entries for SNMPv3-based plugins.
These plugins consume large amounts of memory and for this reason,limited kernel_accel max to 256. This may still be high, but hashcat will automatically tune down kernel_accel if insufficient memory is detected.
Removed command `rocm-smi --resetprofile --resetclocks --resetfans` from benchmark_deep.pl, since some AMD GPUs become artificially slow for a while after running these commands.
Replaced load_source() with file_to_buffer() from shared.c, which does the exact same operations.
Moved suppress_stderr() and restore_stderr() to shared.c and reused them in both Python bridges and opencl_test_instruction(), where the same type of code existed.
Add MAX_THREADS_PER_BLOCK macro to CUDA kernels. It defaults to 1024 or a lower value if limited by the plugin module or specified via the -T command line option.
For CUDA, lower the C++ dialect from C++17 to C++14 to reduce JIT compile time. Also add support for --split-compile and --minimal flags to further improve NVRTC compile performance.
Remove power-hungry NVIDIA settings and fix missing sudo calls in tools/benchmark_deep.pl.
Remove NEW_SIMD_CODE macro from kernels that do not support SIMD (no u32x).
Add support for lower iteration counts per kernel invocation than the default, enabling TMTO for low scrypt configurations, such as N=1024
Use TMTO 2 if it reaches 4 times the device processor count, instead of TMTO 1 always
Improve performance for low scrypt configurations (hash-mode 9300)
Fix unit test for 15700 with correct scrypt configurations
Disable CPU over subscription for SCRYPT based algorithms
Remove hard-coded SCRYPT N, R, and P values in modules, except where they are intentionally hardcoded.
Fix a bug that always caused a TMTO value of 1, even when it was not needed.
Respect device_available_mem and device_maxmem_alloc values even if a reliable low-level free memory API is present, and always select the lowest of all available limits.
Fix benchmark_deep.pl mask to avoid UTF-8 rejects.
Improve error messages when the check verifying that all SCRYPT configuration settings across all hashes are identical is triggered.
Also improve the error message shown when the SCRYPT configuration of the self-test hash does not match that of the target hash.
Fix a bug where a low-tuned SCRYPT hash combined with a TMTO could result in fewer than 1024 iterations, which breaks the hard-coded minimum of 1024 iterations in the SCRYPT kernel.
