    ednel, have you found all the sponsor clues yet?
    Yes, found the sponsors clues - but still have not worked on them as of yet.
    Any hints for the above? I have spent many days on this and still cannot get it. Do not know what I am doing wrong.

    OK!!! Wow and I still have hair. The sponsor clue did not help me, but I tried again to crack it and got some letters, unfortunately I was thinking of another thing .... restarted and got it. OH boy ... why? Who knows.

    I do not understand the Peter's clue at all .. so if someone would PM me on that one ... would be much appreciated. I deciphered it, but now what?

    Default Ch. 11, Q. 4

    I am also having problems with this one? Any hint on what type of cipher, etc. was used is appreciated.

    I just kept trying different phrases, words .... but first I completed the rest of the questions before tackling this one again.

    For the type of cipher, I usually look first to see if letter distribution is completely random, or follows standard probabilities. If the probabilities are standard then it's probably some sort of substitution cipher. Otherwise it's probably a Playfair or Vigenere. To tell the difference there I usually look for things that might break a rule - an odd number of characters can't be Playfair, or if you break the ciphertext into pairs and get a double-letter combo, again probably not a Playfair. Also, if you see some repeating doubles (forward or backwards), this leans a little towards Playfair.

    Simetimes you just can't be sure though.

    Good luck!

    Thx Steve. Will take a look at this one again. Down to about 15 more questions . . . some easy (just need to watch the Da Vinci code) but others appear to be ones that people have struggled with on the message board. I do not think I have had a Vigenere yet so perhaps that is what I am missing. Will let you know how it goes.

    Good luck! BTW, I just noticed I misspoke on my last point; doubles probably indicates Vigenere since you normally won't get doubles with a Playfair (although you always need to be aware of twists!)

    still confused on Q.4 but down to 8 questions remaining to 240!!!! i think I understand your hints but the parenthetical is throwing me off. appears to be a reference to a movie like other questions which should help me back into the key . . . but it only comes up gibberish. don't see this one as a "play" but rather a "v". any other nudges appreciated. having similar issues on C. 6, Q. 14, C. 8, Q. 3, C. 10, Q. 15 and Ch. 12, Q. 10. you can see my lack of experiece in this ciphers.

    Sorry about the parenthetical; in retrospect it was a little unclear. What I meant was that certain pairs of letters are more common than others in normal language, and some of those occur in both directions more fequently (i.e. "at/ta" "le/el"). In a vigenere, these letter pairs are usually represented by different ciphertexts (due to being encoded by different parts of the key), but in a Playfair cipher they always show up the same. So if you see pairs of ciphertext doublets that repeat more than a couple of times, it's probably a Playfair and not vigenere.
