Question
Use each pair of keys to encrypt and decrypt KIBIRANGO SAUL KKUBO. You may use the provided Ascii Table (Appendix A) to convert your name to binary. If you plain test is not multiple of the block size you can add extra zeros at the end of the plain text to make it multiple of the block size.
Solution
The question seems to be incomplete as it does not provide the pairs of keys or the block size to be used for encryption and decryption. However, I can guide you on how to generally encrypt and decrypt a message using ASCII and binary.
-
Convert each character in the message "KIBIRANGO SAUL KKUBO" to its ASCII value. For example, the ASCII value for 'K' is 75, 'I' is 73, 'B' is 66, and so on.
-
Convert each ASCII value to binary. For example, the binary for 75 (K) is 1001011, for 73 (I) is 1001001, for 66 (B) is 1000010, and so on.
-
If the binary string is not a multiple of the block size, add extra zeros at the end until it is. For example, if the block size is 8 and you have a binary string of 1001 (which is 4 bits), you would add four zeros to make it 10010000.
-
To encrypt the message, you would typically use a key to somehow alter the binary string. The exact method depends on the encryption algorithm being used, which isn't specified in the question.
-
To decrypt the message, you would use the decryption key (which could be the same as the encryption key or different, depending on the algorithm) to reverse the encryption process and get back the original binary string.
-
Convert the binary string back to ASCII, and then convert the ASCII back to characters to get the original message.
Without the specific keys and block size, I can't provide a more detailed answer. If you provide those, I'd be happy to help further!

You are given a string s and an integer k. Encrypt the string using the following algorithm:For each character c in s, replace c with the kth character after c in the string (in a cyclic manner).Return the encrypted string. Example 1:Input: s = "dart", k = 3Output: "tdar"Explanation:For i = 0, the 3rd character after 'd' is 't'.For i = 1, the 3rd character after 'a' is 'd'.For i = 2, the 3rd character after 'r' is 'a'.For i = 3, the 3rd character after 't' is 'r'.Example 2:Input: s = "aaa", k = 1Output: "aaa"Explanation:As all the characters are the same, the encrypted string will also be the same. Constraints:1 <= s.length <= 1001 <= k <= 104s consists only of lowercase English letters.
