bad typecode in tiger.hash on line 106

[UntouchedWagons]

Hello

I am trying to use your python implementation of tiger in a personal project. Your code runs fine on my laptop which is using python 2.7.3 but on my desktop it fails which is using python 3.2.3. python 3 complains that 'c' is an invalid typecode as the first parameter to array.array

temp = array.array('c', str[i:])
ValueError: bad typecode (must be b, B, u, h, H, i, I, l, L, f or d)

thanks.
