Kryptos 7 Challenge 3
Our contact with the Red River Gang is under suspicion. She managed to get us a very valuable message that she thinks was encrypted using the Vigenere cipher. However she was questioned before she could send us the key. She later posted a webpage which we think is her way of communicating the key for the Vigenere cipher, but we can’t figure it out. Please help find the key and decode the message!
