![]() (D) First, change all occurrences of "goats" to "foxes." then, change all occurrences of "foxes" to "sheep." Last, change all occurrences of "sheep" to "goats. It is fairly strong for a pencil and paper style code. Playfair: This cipher uses pairs of letters and a 5x5 grid to encode a message. (C) First, change all occurrences of "goats" to "foxes." then, change all occurrences of "sheep" to "goats." Last, change all occurrences of "foxes" to "sheep." A virtually uncrackable cipher that relies heavily upon a random source for an encryption key. (B) First, change all occurrences of "goats" to "sheep." then, change all occurrences of "sheep" to "goats." Last, change all occurrences of "foxes" to "sheep." (A) First, change all occurrences of "goats" to "sheep." then, change all occurrences of "sheep" to "goats." Which of the following algorithms can be used to accomplish the programmer's goal? Consider the programmer's goal of changing all occurrences of "goats" to "sheep" and all occurrences of "sheep" to "goats." The programmer will use the fact that the word "foxes" does not appear anywhere in the original text. A programmer completes the user manual for a video game she has developed and realizes she has reversed the roles of goats and sheep throughout the text. Hard drive encryption uses a specific algorithm, or cipher, to convert a physical disk or logical volume into an unreadable format that cannot be unlocked by anyone without the secret key or password that was used to encrypt the drive. ![]()
