I've searched "Python masking" and various other terms in Google and the
python docs and came up with nothing useful.
This is just a bit of a hobby project that was inspired by some assembly
homework that one of my friends is now doing and I did last semester. The
assignment was to create a program that took two strings and XOR'ed the one
by the other.
For example:
mask: secret
data: This is a secret message!
and you would have:
s XOR T
e XOR h
<skip a few>
e XOR i
t XOR s
<starts at the beginning of the mask>
s XOR ' '
So I basically want a mask the same length as my data (in this case, 25), so
I would have:
mask = 'secretsecretsecretsecrets'
The way I'm currently doing it is:
mask = mask * (len(message)/len(mask))
for l, m in zip(message, mask):
word += chr(ord(l) ^ ord(m))
but I'm wondering if there are any easier/more pythonic ways.
Thanks,
Wayne
