ECTF Web200

It was not at all a web challenge. They gave us a PCAP file and told us to find the secret message passed during the conversation.  I opened it up in Wireshark and examined its stream content. And found these two streams interesting:

Encryption method is Plain text -> Base 64 -> tigo 3FX -> feron 74 -> Encrytion

Cipher: dYauRT/HQz0PPFoTdmRFRzkFNFwnqvOjdF=HWlMbuaw4

Decrypting technique is just to reverse the encrypting process:

Cipher -> feron74 -> tigo3FX->Base64 -> Plain text

This website helped me to solve this problem: http://axcrypt.anonimosx.net/

And the Secret Key was the corruption Queen: Sonia Gandhi
