Ubuntu - what are the commands used to decrypt a ciphertext with an encryption key? - Use pictures to show the commands used for this
Is it feasible to encrypt anything from my device to your server? I don't see how this helps anything. Describe an application of encryption and the benefits it brings.
Assume that you want to make the message available to the users who are authorized to read the respective message. Each message contains some confidential data; therefore, instead of sending the plain text to each user, you decided to encrypt each message using secret key encryption and make the encrypted messages available for read. You need to distribute the encryption keys with the encryption methods to the authorized users. The communication channel between the users and the website is insecure; however, the pubic keys of the users are encrypted through double encryption methods for 2-layer of authentication mechanism and convert into cipher text as follows.
The following cipher message was produced using the Rail Fence algorithm with 3 rails: “WECRLTEERDSOEEFEAOCAIVDEN” What is the corresponding plain text?What’s wrong with the shift cipher? Provide any three reasons.
