Per guidance from your instructor, in a terminal run the following commands: Check the version of OpenSSL by running: openssl version. Create a text file named txt with any text as its contents. Encrypt this file using AES: openssl enc -aes-256-cbc -salt -in test.txt -out test.enc Encrypt this file using AES and Base64 Encode: Same as above but add –a option and use the output enc file as the input into the decrypt. Why would you Base64 encode a file? Decrypt both of the files. Download or locate 2 image files (shown as pic1.png and pic2.png below). Create MD5 Hash on Pic 1 by running: openssl dgst –md5 pic1.png Create MD5 Hash on Pic 2 by running: openssl dgst –md5 pic2.png What is steganography? How could hashing be used to prevent steganography? Create a password by running: openssl passwd [Your Text Here] Take a screenshot of the demonstration.
No written by hand solution Encrypt the plans.txt file using the password pinky and save the output to /opt/book/encryption/secret-key/plans.aes. h. Provide a screenshot of the output in terminal and a screenshot of the contents of the folder opt/book/encryption/secret-key /. Commands to be used: • cd /opt/book/encryption/secret-key • aescrypt -e plans.txt -p pinky -o plans.aes i. Explain what type of encryption aes is, and what is the main difference between aes and RSA encryption algorithm
This question is designed to gain more experience on symmetric encryption algorithms, encryption modes. The cryptographic library implemented by OpenSSL project will be used in this question. Using OpenSSL from the command line interface Create a new text file using a notepad or any other software, The text file contains your name(first 8 chars) and the file must be exactly 8 bytes in size only and name it “txt”. Print screen of your public ip address, repeat it twice and convert it to hexadecimal format then Create another text file and name it “key.txt” contains the doubled IP address in hexadecimal format. Encrypt the file “txt” using DES, using key.txt as a key and ECB mode of operation. The ciphertext should be in a file named “your_id.enc” and print screen your steps in details. [ Prove and explain by details that the avalanche effect is exist in DES algorithm. you don’t have check the existence of avalanche effect using different plaintext only you can use different keys to…
