https://docs.python.org/3/library/stdtypes.html#int.to_bytes To convert an int to the exact number of bytes required, the docs recommend "x.to_bytes((x.bit_length() // 8) + 1, ...)". This is incorrect when length is a multiple of 8, e.g. 296. The correct way is "x.to_bytes((x.bit_length() + 7) // 8, ...)".
