NPU第三届探索解密趣味密码比赛WriteUp

这是我第一次打CTF，所以也没啥成绩，各位权当一乐

签到

按照提示得到flag{Welcome!}

BASE233

根据源码中

static const string base233_chars = "0B7UDomA2ZtJaOFdje43G9zRX1HTnfkhwqElc{WuLPI}bsypCY5SKrQN8gMiVvx6";

base233_chars也是64个字符，同时向下看

char_array_4[0] = (char_array_3[0] & 0xfc) >> 2;
char_array_4[1] = ((char_array_3[0] & 0x03) << 4) + ((char_array_3[1] & 0xf0) >> 4);
char_array_4[2] = ((char_array_3[1] & 0x0f) << 2) + ((char_array_3[2] & 0xc0) >> 6);
char_array_4[3] = char_array_3[2] & 0x3f;
          

4个一组解密，推测是换表base64加密

利用 http://web.chacuo.net/netbasex 解密即可

确定前5位后爆破起来容易很多

import hashlib

string = "86176"

for num in range(0,99999999):
    tempstr = str(num).zfill(8)
    if (hashlib.sha256((string+tempstr).encode('utf-8')).hexdigest()) == 'd64935ee63aac7d30a734395699093b954ab1487ea4e28fa16cf7c82d44513dc':

        print(hashlib.sha256((string+tempstr).encode('utf-8')).hexdigest())
        break
    else:

寄，就不能晚点给hint么，刚费半天劲查到176就给了个hint

观察txt，全为base64，逐行解密发现均为歌词，考虑base64隐写

base64chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'

flag = ''
with open('in.txt', 'r') as f:
    for line in f.readlines():
        line = line[:-1]
        num = line.count('=')
        if num == 0:
            continue
        lastchar = line[-(num + 1)]

        myindex = base64chars.index(lastchar)
        bin_str = bin(myindex)[2:].zfill(6)
        flag += bin_str[6 - 2 * num:]
print(''.join([chr(int(flag[i:i + 8], 2)) for i in range(0, len(flag), 8)]))

根据p^q和p*q计算出p和q的值，求解代码如下

import math

    kmask = (1 << k) - 1
    p &= kmask

    kbit = 1 << (k-1)
    assert a < kbit
    yield a
    yield a | kbit

def factor(n, p_xor_q):
    tracked = set([(p, q) for p in [0, 1] for q in [0, 1]
                   if check_cong(1, p, q, n, p_xor_q)])

    PRIME_BITS = int(math.ceil(math.log(n, 2)/2))

    maxtracked = len(tracked)
    for k in range(2, PRIME_BITS+1):
        newset = set()

                    if check_cong(k, newp, newq, n, p_xor_q):
                        newset.add((newp, newq))

        tracked = newset

            maxtracked = len(tracked)
    print('Tracked set size: {} (max={})'.format(len(tracked), maxtracked))

    for p, q in tracked:
        if p != 1 and p*q == n:
            return p, q

    assert False, 'factors were not in tracked set. Is your p^q correct?'

def main():
