* changes v3.10 -> v3.20:
|

|
||||
The hashcat core was completely refactored into a library (libhashcat).
|
||||
This should help developers to include hashcat into distributed clients or GUI frontends (see main_shared.c for a quick start).
|
||||
The hashcat core was completely refactored into a MT-safe library (libhashcat).
|
||||
The goal was to help developers to 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.

|

##
|
||||
## Algorithms
|
||||
##
|
||||
|
||||

|
||||

|
||||
|
||||
##
|
||||
## 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 22 = Juniper Netscreen/SSG (ScreenOS): Fix salt length for -m 22 in benchmark mode
|
||||
- Hash-Mode 5500 = NetNTLMv1 + ESS: Fix loading of NetNTLMv1 + SSP hash
|
||||
- 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 that 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 in case if used in combination with --show or --left
|
||||
|
||||
