I'm trying to learn how to go about cracking RC4 ciphers (nothing illegal, its an old, i.e., not active challenge for a job application, so no cheating).
I have nine md5 hashes with their own ciphers. One cipher is significantly shorter than the rest. Two "ciphers" are blanks with only MD5 hashes. Six ciphers are of the same length.
They hint that the key is very long, and my assumption is that brute forcing the key is out of the question. In the python code that they provided, I can see that the same key has been used for each cipher.
Any guidance on how to do this? I've been at it for the past week, learning quite a bit, but not enough.
There is one class in their code that says it's a test and will be removed later. That could be a possible hint and potentially be plaintext I suppose.
