Environment

- **OS**: Not OS related
- **Sage Version**: 10.0

Steps To Reproduce

from sage.crypto.sbox import SBox
S = SBox(0,0,0,1,0,0,1,3)
S.difference_distribution_table()

Expected Behavior

The correct distribution table.

Actual Behavior

IndexError Traceback (most recent call last)
Cell In [23], line 3
1 from sage.crypto.sbox import SBox
2 S = SBox(Integer(0),Integer(0),Integer(0),Integer(1),Integer(0),Integer(0),Integer(1),Integer(3))
----> 3 S.difference_distribution_table()

651 for di in range(nrows):
--> 652 L[di*nrows + si ^ self._S_list[i ^ di]] += 1
653
654 A = matrix(ZZ, nrows, ncols, L)

IndexError: list index out of range

Additional Information

It works with a square SBox, but fails with non-square one. I presume the "range(nrows)" in line 651 should be "range(ncols)".
