Some basic xor related python scripts that I wrote a long time ago. xor.py: Simply XORs ascii strings given on the command line e.g. ./xor.py "AAA" "123" xor_files.py: XORs two files together e.g. ./xor_files.py file1.py file2.py xor_fkey.py: XORs a file with a "key" from the command line e.g. (key = 0x4141419999EE) ./xor_fkey.py test0.bin 41 41 41 99 99 EE
