In the past, encryption and decryption were mostly done by substitution and permutation of letters in a text message. study those classic cryptographic schemes Then, develop an automatic cipher using Javascript The cipher should be able to perform the following tasks:
generate keys
encrypt a given plaintext message with a key selected from the list of keys generated
decrypt a given ciphertext message with a known cipher key
List reasons why teachers should and shouldn’t be replaced by computers? State your response in a descriptive context. Provide five references from the with internet with your answers.

- Case Study Instructions: Offshore Wind Energy in the North Sea For this case study, students will analyze the institutional challenges and social rules surrounding offshore wind energy development in the Dutch North Sea, as explored in the case study from the textbook (pages 44-46). Additional resources in this week’s learning module will provide further perspectives on the impact of wind energy on different stakeholders. Students should refer to the syllabus for specific guidelines regarding length, format, and content requirements. Reflection Questions to Consider: What are the key institutional challenges in implementing offshore wind energy in the North Sea? How do formal and informal social rules shape the use of this shared space? What conflicts arise between different stakeholders (e.g., fishermen, naval transport, military, and wind energy developers)? How can policymakers balance economic, environmental, and social considerations when allocating space for wind energy?…arrow_forwardAlphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.arrow_forwardI would like help to resolve the following casearrow_forward
