Hello! I am a Uni student and for a project in Information Systems Security due in just under two weeks, I have tried to make a Python version of the Biham / Anderson Tiger Hash function. I have put the original C source and my two files Tiger.py and doHash.py on my website:
http://www.users.on.net/~mlivingstone/ My problems are doubtless basic since I have been teaching myself Python. My best knowledge is Java :-( Firstly, in doHash.py, I cannot invoke tiger() without getting unbounded errors and / or complaints about no such method. The C code is peppered with typedefs for word64 and word 32 and byte and I am unsure how to treat these. t2, t3, t4 are some sort of index into the S-Box table. How can I pythonise them? I don't expect you to write my program for me but any help / clues would be gratefully received. I have been using the latest Core Python Programming 2E by Wesley Chun which has been very helpful but I have not found help for these specific areas. I have taken out all the Bigendian code, Alpha code and ternary operator within ternary operator code but the C is still a bit complex for me. Many thanks in advance for your help MarkL -- http://mail.python.org/mailman/listinfo/python-list
