Error: could not load path(s) in 'data/bestpath.bin.gz'! #3

Closed 3r1kd0f closed 5 years ago

Hi, First of all thank you for making this great tool available to everyone ! When trying to reproduce the example with the PNG file I get the error below. Any suggestions how to fix this ? I wanted on purpose to re-run everything from scratch using Hashcalsh (not to use the pre-computed file) Many thanks !!

$ python2 pngStd.py yes.png no.png

just retry, sometimes UniColl is not working at the first try. if it keeps failing, you may want to try the autokillfix branch of hashclash.

cr-marcstevens commented 5 years ago

The log shows that it tries to load precomputed upper paths directly, but that these either do not exist or are corrupted. Try to remove the directory upper1 and then rerun.

Many thanks for the fast response! Indeed removing upper1 fixed the issue
