* changes v3.20 -> v3.21:

|
##
|
|
## Features
|
|
##
|
|
|
|
- New option --progress-only: Quickly provides ideal progress step size and time to process on the user hashes and selected options, then quit
|
|
- Files: Use $HEX[...] in case the password includes the separater character, increases potfile reading performance
|
|
|
|
##
|
|
## Bugs
|
|
##
|
|
|
|
- Fixed infinite loop when using --loopback in case all hashes have been cracked
|
|
- Fixed double fclose() using AMDGPU-Pro on sysfs compatible platform: Leading to segfault
|
|
- Fixed kernel loops in --increment mode leading to slower performance
|
|
- Fixed custom char parsing code in maskfiles in --increment mode: Custom charset wasn't used
|
|
- Removed access to readlink() on FreeBSD: Causes problem building hashcat
|

|
|
|
|
- Sanity: Added sanity check to disallow --speed-only in combination with -i
|
|
- Potfile: In v3.10 already, the default potfile suffix changed but the note about was missing. The "hashcat.pot" became "hashcat.potfile"
|
|
- Threads: Replaced all calls to strerror() with %m printf() GNU extension to ensure thread safety
|
|
- Threads: Replaced all calls to ctime() with ctime_r() to ensure thread safety
|
|
|
|
* changes v3.10 -> v3.20:
|
|
|
|
The hashcat core was completely refactored to be a MT-safe library (libhashcat).
|
|
The goal was to help developers include hashcat into distributed clients or GUI frontends.
|
|
The CLI (hashcat.bin or hashcat.exe) works as before but from a technical perspective it's a library frontend.
|

|
|
## Features
|
|
##
|
|
|
|
- New option --speed-only: Quickly provides cracking speed per device based on the user hashes and selected options, then quit
|
|
- New option --keep-guessing: Continue cracking hashes even after they have been cracked (to find collisions)
|
|
- New option --restore-file-path: Manually override the path to the restore file (useful if we want all session files in the same folder)
|
|
- New option --opencl-info: Show details about OpenCL compatible devices like an embedded clinfo tool (useful for bug reports)
|
|
- Documents: Added colors for warnings (yellow) and errors (red) instead of WARNING: and ERROR: prefix
|
|
- Documents: Added hints presented to the user about optimizing performance while hashcat is running
|
|
- Hardware management: Support --gpu-temp-retain for AMDGPU-Pro driver
|
|

|
|
- Password candidates: Allow words of length > 31 in wordlists for -a 0 for some slow hashes if no rules are in use
|
|
- Password candidates: Do not use $HEX[] if the password candidate is a valid UTF-8 string and print out as-is
|
|
- Pause mode: Allow quit program also if in pause mode
|
|
- Pause mode: Ignore runtime limit in pause mode
|
|
- Status view: Show core-clock, memory-clock and execution time in benchmark-mode in case --machine-readable is activated
|
|

## Bugs
|
|
##
|
|
|
|
- Custom charset from file parsing code did not return an error if an error occured
|
|
- Fix some clSetKernelArg() size error that caused slow modes to not work anymore in -a 1 mode
|
|
- Hash-mode 11600 = (7-Zip): Depending on input hash a clEnqueueReadBuffer(): CL_INVALID_VALUE error occured
|
|

|
|
- Hash-mode 6000 = RipeMD160: Fix typo in array index number
|
|
- If cracking a hash-mode using unicode passwords, length check of a mask was not taking into account
|
|
- If cracking a large salted hashlist the wordlist reject code was too slow to handle it, leading to 0H/s
|
|
- Null-pointer dereference in outfile-check shutdown code when using --outfile-check-dir, leading to segfault
|
|
- On startup hashcat tried to access the folder defined in INSTALL_FOLDER, leading to segfault if that folder was not existing
|
|
- Random rules generator code used invalid parameter for memory copy function (M), leading to use of invalid rule
|
|
- Sanity check for --outfile-format was broken if used in combination with --show or --left

##
|
|
|
|
- Fixed a bug in speed display: In some situation, especially with slow hashes or lots of salts, it showed a speed of 0H/s
|
|
- Fixed a bug in restore handling: user immediately aborting after restart broke the restore file
|
|
- Fixed a bug in line counter: conditional jump or move depends on an uninitialised value
|
|
- Fixed a bug in rule-engine for NVidia devices: code for left- and right-shift were switched
|
|
- Fixed a bug in dive.rule: rules were not updated after the function 'x' was renamed to 'O'
|
|
- Fixed a bug in memory allocation "OpenCL -4 error": used unitialized value in a special situation
|
|
- Fixed a bug in memory handling: heap buffer overflow
|

- Fixed a bug in memory handling: out of bounds access
|
|
- Fixed a bug in implementation of DCC2: forced default iteration count for hashes to 10240

|
- Workaround missing clEnqueueFillBuffer() support in certain OpenCL runtimes
|
|
- Added amd_bytealign() support in non-AMD OpenCL runtimes
|
|
- Added amd_bfe() support in non-AMD OpenCL runtimes
|
|
- Added several macros to allow writing optimized code for the different OpenCL platforms
|
|
- Replaced typedef for bool with stdbool.h
|
|
- Added special DEBUG environment variables to the makefile
|
|
- Hashcat now acquires an exclusive lock before writing to any file
|
|
- Changed buffers to not use same buffer for both input and output at the same time with snprintf()
|
|
- Check for allocatable device-memory depending on kernel_accel amplifier before trying to allocate
|
|
- Added additional check for max. ESSID length to prevent possible crashes
|
|
- Use a GCC equivalent for __stdcall where applicable
|
|
- Synchronize maximum output line size with input line size
|
|
- Increased maximum hash line size to 0x50000
|
|
- Run weak-hash checks only in straight-attack mode, this greatly reduces code complexity
|
|
- Restrict loopback option to straight attack-mode
|
|
- Moved rules_optimize to hashcat-utils
|
|
- Stick to older libOpenCL in binary package to avoid errors like this: version `OPENCL_2.0' not found
|
|
- Tightened hash parser for several algorithms
|
|
- Updated old RC4 code in Kerberos 5
|
|
- Limited the salt length of Juniper Netscreen/SSG (ScreenOS) hashes to 10
|
|
- Updated algorithm used to automatically select an ideal --scrypt-tmto value
|
|
- Renamed option --gpu-accel to --kernel-accel
|
|
- Renamed option --gpu-loops to --kernel-loops
|
|
- Renamed option --gpu-devices to --opencl-devices
|
|
- Added inline declaration to functions from simd.c, common.c, rp.c and types_ocl.c to increase performance
|
|
- Dropped static declaration from functions in all kernel to achieve OpenCL 1.1 compatibility
|
|
- Added -cl-std=CL1.1 to all kernel build options
|
|
- Created environment variable to inform NVidia OpenCL runtime to not create its own kernel cache
|
|
- Created environment variable to inform pocl OpenCL runtime to not create its own kernel cache
|
|
- Dropped special 64-bit rotate() handling for NV, it seems that they've added it to their OpenCL runtime
|
|
- Completely get rid of HAVE_ADL, HAVE_NVML and HAVE_NVAPI in sources
|
|
- Replaced NVAPI with NVML on windows
