MATLAB Please help with encryption. Then main program should then call a function encrypt message which should • take in the message to encrypt and the keyword • subtract 'a' from each element of the message (so the letter a is now 0) • subtract 'a' from each element of the keyword • encrypt the message using the keyword as described above (hint: first handle the letters encrypted using k0, then those encrypted using k1, etc) • add 'a' to...

Kindly follow the instructions provided carefully. C programming Project 6, Program Design One way to encrypt a message is to use a date’s 6 digits to shift the letters. For example, if a date is picked as December 18, 1946, then the 6 digits are 121846. Assume the dates are in the 20th century. To encrypt a message, you will shift each letter of the message by the number of spaces indicated by the corresponding digit. For example, to encrypt...
I need Help to Write a function in C that will Decrypt at least one word with a substitution cipher given cipher text and key My Current Code is: void SubDecrypt(char *message, char *encryptKey) { int iteration; int iteration_Num_Two = 0; int letter; printf("Enter Encryption Key: \n"); //Display the message to enter encryption key scanf("%s", encryptKey); //Input the Encryption key for (iteration = 0; message[iteration] != '0'; iteration++) //loop will continue till message reaches to end { letter = message[iteration]; ...
Security is an important feature of information systems. Often, text is encrypted before being sent, and then decrypted upon receipt. We want to build a class (or several classes) encapsulating the concept of encryption. You will need to test that class with a client program where the main method is located. For this project, encrypting consists of translating each character into another character. For instance, if we consider the English alphabet, including characters a through z, each character is randomly...
Write the programming C please, not C++. The main function should be to find the offset value of the ciper text "wPL2KLK9PWWZ7K3ST24KZYKfPMKJ4SKLYOKRP4KFKP842LK0ZTY43 " and decrypt it. In cryptography, a Caesar Cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be...
(b.) Huffman code is a way to encode information using variable-length binary strings to represent symbols depending on the frequency of each individual letter. Specifically, letters that appear more frequently can be encoded into strings of shorter lengths, while rarer letters can be turned into longer binary strings. On average, Huffman code is a more efficient way to encode a message as the number of bits in the output string will be shorter than if a fixed-length code was used....
The Diffie-Hellman public-key encryption algorithm is an alternative key exchange algorithm that is used by protocols such as IPSec for communicating parties to agree on a shared key. The DH algorithm makes use of a large prime number p and another large number, g that is less than p. Both p and g are made public (so that an attacker would know them). In DH, Alice and Bob each independently choose secret keys, ?? and ??, respectively. Alice then computes...
