用记事本打开 介绍.txt 会忽略后面内容，用VScode比较好

属猴，测试密码是1992，打开flag.txt内容是

5+58==327a6c4304ad5938eaf0efb6cc3e53dcCFmZknmK3SDEcMEue1wrsJdqqkt7dXLuS

5的意思是MD5，58的意思是base58

选择前32位进行md5解码md5在线解密破解,md5解密加密 (cmd5.com)

Base58在线编码解码-ME2在线工具 (metools.info)

也可用脚本解Base58

def b58encode(tmp:str) -> str:
	tmp = list(map(ord,tmp))
	temp = tmp[0]
	base58 = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
	for i in range(len(tmp)-1):
		temp = temp * 256 + tmp[i+1]
	tmp = []
	while True:
		tmp.insert(0,temp % 58)
		temp = temp // 58
		if temp == 0:
			break
	temp = ""
	for i in tmp:
		temp += base58[i]
	return temp
 
def b58decode(tmp:str) -> str:
	import binascii
	base58 = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
	temp = []
	for i in tmp:
		temp.append(base58.index(i))
	tmp = temp[0]
	for i in range(len(temp)-1):
		tmp = tmp * 58 + temp[i+1]
	return binascii.unhexlify(hex(tmp)[2:].encode("utf-8")).decode("UTF-8")
 
#print(b58encode("ABDCDEFGA"))
print(b58decode("CFmZknmK3SDEcMEue1wrsJdqqkt7dXLuS"))
