  4. 看大佬文章这是要字频统计,大量无特征、无规律字符。
    先上大佬的脚本

alphabet = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890!@#$%^&*()_+- =\\{\\}[]"
strings = open('./flag.txt').read()

result = {}
for i in alphabet:
	counts = strings.count(i)
	i = '{0}'.format(i)
	result[i] = counts

res = sorted(result.items(),key=lambda item:item[1],reverse=True)
for data in res:
	print(data)

for i in res:
	flag = str(i[0])
	print(flag[0],end="")
