Weak Rsa ..?

Hi everyone, as soon as I entered hackthebox I started with the first challenge of. cryptography (as I had never done this before). I have scrapped Weak Rsa, the simplest I think.
I found a "RsaCtfTool" tool on github.
When I start it in my virtual machine with backbox it gives me an error and I can not fix it.
Can someone tell me another tool?

Hack The Box



  • Hi, it's the tool for this challenge (i used it) maybe it's your command.
    you can PM me if needed

  • I'll try ! thanks.

    Hack The Box

  • I've had to give up on this as I just can't get the dependencies for RsaCtfTool installed. I got bored of messing around with trying to get it working


  • @sender said:
    Actually it is working with an older version I had in my notes. Could not get it to work with the recent version either. I uploaded the working tool https://www.file-upload.net/download-12991101/rsa_ctf_tool.zip.html .

    This is from another Weak RSA forum. It worked for me.

    I was having trouble using the exact same tool that I found through google, but apparently there is something wrong with the easily found version.

    The website it links to is kind of a pain in the ass, but the download is legit.
