题目给了一个pdf文档

 

 

这应该是一个PEM文本的截图，从第一行可以看出这是rsa私钥，有了私钥就好说了，直接解密就可以

但是只有部分数据可见，现在的任务应当就是恢复完整的PEM文本

 

先从图片里提取文字：

把pdf转化为图片，使用imagemagick，采用这条命令安装：sudo apt-get install imagemagick

再用tesseract-ocr提取图片中的文字，采用这条命令可以安装该软件：sudo apt-get install tesseract-ocr

convert  -density 400 ./RSA_key.pdf ./abcd.png
tesseract abcd.png abc

如果执行convert命令报错

convert: not authorized `./RSA_key.pdf' @ error/constitute.c/ReadImage/412.
convert: no images defined `./abcd.png' @ error/convert.c/ConvertImageCommand/3210.

可以尝试把/etc/ImageMagick-6/policy.xml里的 <policy domain="coder" rights="none" pattern="PDF" />

改为<policy domain="coder" rights="read|write" pattern="PDF" />，

 

我们看下生成的abc.txt的内容：

不是很理想，可能因为我参数设置的有问题

还是用photoshop分离图片，再tesseract提取文字，从图片的大小和行间距离，可以估测出整个文本在50行左右，那应该就是rsa 4096位的加密，我们把隐藏的文本用0代替

用PEM文件存储RSA私钥，实际上是把私钥用base64加密，按照n,e,d,p,q, d mod(p-1), d mod(q-1), q-1 mod (p)的顺序排列，其间有特定的分隔标志。我们构造一个正常的PEM文件，观察下它的结构

from Crypto.PublicKey import RSA
key = RSA.generate(4096)
print("n:"+hex(key.n))
print("e:"+hex(key.e))
print("d:"+hex(key.d))
print("p:"+hex(key.p))
print("q:"+hex(key.q))
print("dp:"+hex(key.d%(key.p-1)))
print("dq:"+hex(key.d%(key.q-1)))
print("q_mod_p:"+hex())
pem = key.export_key('PEM')
print(pem.decode())

现在我们利用dp来恢复整个私钥

 

可以一一求出p和q，也可以求出p后，通过q=inverse(q_inv,p)求出q（因为(q*q_inv)%p=1）

因为(p-1)>dp，所以Kp<e，Kq也是一样，许多情况下e等于65537，因此K完全是可以遍历得到的（如果e不等于65537该怎么办呢）
