Use the two prime numbers p = 5 and q =13 in the first step to give ONE integrated example to show how the five steps in the basic process of RSA Cryptography works. Based on your example, demonstrate how the number 60 as an original message is encrypted into ciphertext and decrypted back correctly to the original message. If you need to choose a number in any step, you must choose it from the set {x e R: 8 < x < 12}. You must show all detailed steps involved.

Can I have the solution for this question.
A Caesar cipher is a simple substitution cipher based on the idea of shiftingeach letter of the plaintext message a fixed number (called the key) ofpositions in the alphabet. For example, if the key value is 2, the word"Sourpuss" would be encoded as "Uqwtrwuu." The original message canbe recovered by "reencoding" it using the negative of the key.Write a program that can encode and decode Caesar ciphers. The input to the program will be a string of plaintext and the value of the key.The output will be an encoded message where each character in the original message is replaced by shifting it key characters in the Unicode character set. For example, if ch is a character in the string and key is theamount to shift, then the character that replaces ch can be calculated as:chr (ord(ch) + key) .
Evaluate the following FOL-wff using the given interpretation: (Vz)(Q(x) (By)(P(r,y) (Vx)P(y, r))) 1. U= {a, b} IT y P(r,y) y Q(y) a a. a a. b. a
Write a Perl program that uses a hash and a large number of operationson the hash. For example, the hash could store people’s names and theirages. A random-number generator could be used to create threecharacter names and ages, which could be added to the hash. When aduplicate name was generated, it would cause an access to the hash butnot add a new element. Rewrite the same program without using hashes.Compare the execution efficiency of the two. Compare the ease ofprogramming and readability of the two.

The Reflection algorithm can be used to encrypt a C-string (character array terminated with the null character) before it is transmitted over the Internet. The Reflection algorithm works as follows: Each letter in the message is converted to the letter in that is 13 positions to the right of that letter in the English alphabet. If the end of the alphabet is reached, counting continues from the first letter in the alphabet. The case of the letters must be maintained. For example,'M' →'Z', 'x' → 'k', 'A' → 'N'The numeric characters ('0' to '9') are shifted 5 positions to the right of that number in the character set '0' to '9'. If ‘9’ is reached, counting continues from ‘0’. For example,'0' → '5', '2' →'7', '8' → '3' All other characters are left as they are. a) What would the following string be encrypted to by the Reflection algorithm?“Call me at 662-2002 Ext 85393” b) Write a function, getPosition, which finds the position of a letter in the alphabet regardless of the case of the…

Write the program in PHP....You are given a dataset of N students belonging to the same class. The data containsname of the student followed by marks they scored in five subjects which are Physics,Chemistry, Mathematics, English, and Hindi. Your task is finding the average markof the class for each individual subject (Use Associative array and function)Input Format:First line will contain an Integer N, denoting the number of students in the class.Each of the Next N lines will contain a string S denoting the student name, followed byfive integers m1, m2, m3, m4, m5 denoting the marks scored in each subject.Constraints1 <= N <= 10^3 1 <= S <= 10^2 0 <= m1, m2, m3, m4, m5 <= 100
just need an advice language: python so I'm working on this substitution cipher where a user will input a statement plus randomized a-z letters. so the scenario goes like this: alphabet = abcdefghijklmnopqrstuvwxyz statement = abyz if the randomized a-z letters = qwertyuiopasdfghjklzxcvbnm then output should be: qwnm (q=a, w=b, e=c, and so on..). where every small caps letter on the statement excluding the punctuation marks or whatsoever, will be substituted with its equivalent in the randomized a-z letter. my problem is, i am limited to using only while loops, iterations, if-elif-else statements. i CANT use for loops, len(), lists, and other stuffs. any idea on how i can make my program work out? i've been thinking since earlier morning and over 24hrs later and i still cant figure it out.
The Virtual Weight (VW) of an integer number (which consists of more than 1 digit) is the sumof the individual digits that are composing the number. For example, consider the followingtwo numbers; 5638 and 1145, then the VW of each is calculated as following:VW(5638) = 5+6+3+8 = 22VW(1145) = 1+1+4+5 = 11Then, the VW can be classified as L (mean Low) or H (means High) using a specific cut-offvalue. For example, if the cut-off value is 15, then the VW of the number 5638 is H (High),and the VW of the number 1145 is L because 22 > 15 and 11 ≤ 15 respectivelyWrite a C++ program that: reads a positive integer n (where 5≤n≤20) from the user. If the user enters invalidnumber, then the program should continue prompting until he/she enters a valid numberwithin the specified range. Then, the program should generate n random numbers using the built-in rand()function. Every time a random number is generated, the program will classify that number as Lor H using the above method. Use a…
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1 Ex: If the input is: 7 the output is: fibonacci (7) is l3 Note: Use recursion and DO NOT use any loops.
