Build
|
|
-----
|
|
|
|
It requires an OpenCL framework.
|
|
|
|
If required, edit Makefile and adjust INCLUDE and LIBS directives to your setup.
|
|
|
|
```
|
|
make clean
|
|
make
|
|
```
|
|
|
|
Run
|
|
---
|
|
|
|
You'll need just two nR aR pairs. These are the
|
|
encrypted nonces and challenge response values. They should be in hex.
|
|
|
|
```
|
|
./ht2crack5opencl <UID> <nR1> <aR1> <nR2> <aR2>
|
|
```
|
|
|
|
UID is the UID of the tag that you used to gather the nR aR values.
|
|
|
|
Usage:
|
|
|
|
```
|
|
$ ./ht2crack5opencl
|
|
./ht2crack5opencl [options] {UID} {nR1} {aR1} {nR2} {aR2}
|
|
|
|
Options:
|
|
-p : select OpenCL Platform(s). Multiple allowed (1,2,3,etc.). [Default: all]
|
|
-d : select OpenCL Device(s). Multiple allowed (1,2,3,etc.). [Default: all]
|
|
-D : select OpenCL Device Type. 0: GPU, 1: CPU, 2: all. [Default: GPU]
|
|
-S : select the thread scheduler type. 0: sequential, 1: asynchronous. [Default 1]
|
|
-P : select the Profile, from 0 to 10. [Default: auto-tuning]
|
|
-F : force verify key with OpenCL instead of CPU. [Default: disabled]
|
|
-Q : select queue engine. 0: forward, 1: reverse, 2: random. [Default: 0]
|
|
-s : show the list of OpenCL platforms/devices, then exit
|
|
-V : enable debug messages
|
|
-v : show the version
|
|
-h : show this help
|
|
```
|
|
|
|
Example,
|
|
|
|
```
|
|
simple
|
|
|
|
./ht2crack5opencl 2ab12bf2 4B71E49D 6A606453 D79BD94B 16A2255B
|
|
|
|
select devices 1, 2 and 3 using platform 1 and 2, with random queue engine:
|
|
|
|
./ht2crack5opencl -D 2 -Q 2 -p 1,2 -d 1,2,3 2ab12bf2 4B71E49D 6A606453 D79BD94B 16A2255B
|
|
```
|
|
|
|
|
|
You can find the correct OpenCL Platform ID (-p) and Device ID (-d) with:
|
|
|
|
```
|
|
./ht2crack5opencl -s
|
|
```
