So I am trying to solve this really interesting Crypto challenge, Infinite Descent. I (think) have decoded the given message using private key and I used the result to generate AES key (don’t know it’s correct or not). Now I am not sure what’s the next step, I tried submitting the key as flag but failed. Can anyone please give me a hint? Thanks.
take a look at the files provided to you again, especially the python scripts. Read them again (including the comments) and figure out the next step.
I’m close but I think I’m similarly stuck. Have extracted the private key and verified it’s write by just using it in encrypt/decrypt operations on dummy data. Decrypted the message but think I’m screwing up the last part inadvertently. May be misreading the context from the comments.
