Implement a subroutine of the Caesar shift encryption. It is a simple substitution encryption algorithm, in which each letter is replaced by a letter with a fixed number of offset down in the alphabet. For example, with a shift offset of 3, A would become D, and B would be replaced by E, and so on.

Implementing a very basic encryption scheme known as a caesar cipher. The caesar cipher involves shifting every letter in the given string by a given number in the alphabet. Please help me write a NASM assembly language program that: Asks the user for a number between -25 - 25 (-25 <= num <= 25) You have to do error correction

Write a python program. Add a function called reverse() that outputs a DNA strand in reverse. Example: reverse(AATC) returns CTAA Note: you should not use the built-in reverse method.

Write a program on python that simulates the toss of a six sides die. What is the ratio of the number 2 with the other sides?. Assume that each side has equal probability to appear when a die is tossed.

Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the choice to return to the main menu or select a person to overwrite. When…

Write Python commands, within a print command, that output the following. (E.g. print(list(range(10))) , in spyder (vi)   Let x = [1,3,5] and let y = [2,4,6]. If we interpret these as vectors x and y then the vector sum can be written x + y = [x[0]+y[0],x[1]+y[1],x[2]+y[2]]. Find an the equivalent expression for the vector dot product x⋅y. (vii)   With x,y as above find an expression for the vector cross product x * y.

Discrete distribution. Write a program DiscreteDistribution.java that takes an integer command-line argument m, followed by a sequence of positive integer command-line arguments a1,a2,…,ana1,a2,…,an, and prints m random indices (separated by whitespace), choosing each index i with probability proportional to ai.  example: input = 25 1 1 1 1 1 1  output = 4135236543212345634523453

Print the following pattern in C

USING KEIL PLEASE.. Ciphers use many bitwise operations for cryptography. Write an ARM assembly program to use ciphers. See the steps below to implement the cipher. In this program, you will implement a "Symmetric Encryption".    Create three variables, Plaintext, Key, and Cipher (5 Points) For encryption, design a key value, assign the last nonzero number of your student ID (#900 number) in a variable called “Key” (5 Points) For example: if your 900 number is 90012450. Assign 5 to the variable Key and use it as the Key for encryption. Use this link for the Links to an external site.video to understand Symmetric Key Cryptography and implement that for encryption and decryption.  For the variable Plaintext, assign any four-letter word. Encrypt the plaintext using the value in Key and store the encrypted text in the variable Cipher.  Test the encryption by decrypting and storing the decrypted text into register R5.
