You have to answer the following question-

We received the given ciphertext which was encoded with a shift cipher: xultpaajcxitltlxaarpjhtiwtgxktghidhipxciwtvgtpilpitghlxiwiwtxgqadds.

Problem- 1 Perform an attack against the cipher based on a letter frequency count: How many letters do you have to identify through a frequency count to recover the key? What is the cleartext?

Problem - 2 Who wrote this message?

Please give a detailed answer so that I may learn from it. Thank you!
