Ancient Signal
Additional Info
Description
The starship Voyager received an unusual communication. The flag is with „curlybraket” word in place of ’{’ and ’}’ but you have to submit it in the CTF{sha256} format.
The challenge is based on a network capture file containing two communication streams: an FTP stream and a TLS stream.
The FTP stream contains the TLS sessions keys used to decrypt the TLS stream.
