I generate a hexadecimal number 0xffffffffffffffffffffffffffffffff like
s=0
for i in range(128):
s=s+2^i
s=hex(s)
I want to make it string like 'ffffffffffffffffffffffffffffffff' so that I can pass it as follows:
from sage.crypto.mq.rijndael_gf import RijndaelGF
rgf = RijndaelGF(4, 4)
state = rgf._hex_to_GF('ffffffffffffffffffffffffffffffff')
