Thank you for decryption this. Although I have to agree with the comments above. If in the exam they ask "How would you attack this cipher if you were given this info" I don't think they would be to impressed if i said "Post to crypto.stackechange.com". I would be interested to know how you achieved this so I could do it again to a different ciphertext with a different key/plaintext.

PS I have now tried Pygenere again and it does not yield the message. Keep in mind that I am only guessing that this is Vigenere. Is there any way to work out if that is correct?

Hey thank you for the advice, I had noticed the HIMFTF myself. but the reason why I know the length is 6 is because the person that encrypted the message (The tutor for my class) told me that it was 6 long and that it repeats.

I disagree with the fact that this isn't the place to ask. Reading the FAQ it says that its not ok to "Can I challenge people to decode something?" but it does also say that you can ask homework questions. I believe thats what im asking. I am not really after the solution more how would one approach this question given the limited ciphertext and that I have tried the attacks I know of.
