addition to: What is the best way to go about using Cryptanalysis to decrypt a message?

I am glad that I found this thread, as I now have the same assignment. I am having a problem with this.. I have followed the instructions and have solved most of the assignment. However, the addition to the assignment is to find the KEYWORD. I am having a problem with that part of it.

Can anyone point me in the right direction to find the keyword?

Thank you in advance

Do you know what kind of encryption was used?
if it is a simple substituton cypher, you might start with a frequency analysis and compare it the frequency distributions of plaintext strings.
If it is a Vigenère cipher, you might compute the index of coincidence at various shifts to get an idea of the length of the key, and do separate frequency analysis for each column
If you have an idea of some if the words that may be included in the message, you might try crib dragging, to see if it fits anywhere, and if that produces some clues

You might want to try a software application called CypTool.  It allows you try to play with different algorithms.  

As for decrypting that, if it is AES or similar, I doubt you will be able to crack it with publicly  available tools.

Do you have any decrypted text?  Or only the cyphertext?

I figured it out.  It was a substituton cipher.  The keyword was embeded in the cipher.
