@NameOfFool unless you patched the binary I don't think that is correct. There is a "hash function" that needs to be reversed to reveal the key to print the correct input message.
key sha1 e6f2df5e3248824c62840e71dcfe639e7da7a569

As mentioned by dev0 hash function needs to be reverse engineered.
CTF key hash sha2-256 is 76bd1ce2c417d18ab997fc6b27e6782b164ee451bf729cfea56e7dfeff2d5d6e

Use ghidra to disassemble and decompile, then observe the call and functions...
anon786 on 2024-10-15 18:29:
sha3-256 of the CTF key is: 7a616e031f268ca600e41ae389b7a116e9cdeaaa1ea3cf4ec136cef01631247f

Just wanted to thank you for this submission!
This was the first CTF I've ever done and it was super fun!

Solution by NomanProdhan on 2024-10-29 15:01: I used Ghidra to analyze and solve the challenge and included a Python script in the PDF to generate the actual.
