解法：
legal_chars = "01234567890abcdefghijklmnopgrstuvwxyzABCDEFGHIGKLMNOPQRSTUVWXYZ "
with open("f:\\4.txt") as fin:
for line in fin.readlines():
x = bytes.fromhex(line.strip())
for i in range(256):
y = [chr(i^sx) for sx in x]
if len([c for c in y if c in legal_chars]) > 0.8 * len(x):
print(line, i, ‘‘.join(y))
感想：
没有仔细读题，还以为就是S1-3的放大版
