Need help writing code for RC4. C++ Implement the RC4 stream
Implement the RC4 stream cipher in C++. User should be able to enter any key that is 5 bytes to 32 bytes long. Be sure to discard the first 3072 bytes of the pseudo random numbers. THE KEY OR THE INPUT TEXT MUST NOT BE HARD CODED IN THE PROGRAM. Test your program with the following plain text: In cryptography, RC4 (Rivest Cipher 4 also known as ARC4 or ARCFOUR meaning Alleged RC4) is a stream cipher. While remarkable for its simplicity and speed in software, multiple vulnerabilities have been discovered in RC4, rendering it insecure. It is especially vulnerable when the beginning of the output keystream is not discarded, or when nonrandom or related keys are used. Particularly problematic uses of RC4 have led to very insecure protocols such as WEP. You should write two programs: encryption and decryption. The encryption program should input the plaintext file and output a cipher text in hex. The decryption program should input the cipher text file in hex and output the plaintext. Submit the following: 1. Source code of the encryption program. 2. A screen shot showing the encryption with a 5 byte key. 3. The cipher text from the encryption, saved in hexadecimal (you may want to use the “hex” output manipulator) 4. Source code of the decryption program. 5. A screen shot showing the decryption of the cipher text with the same 5 byte key. 6. The plaintext from the decryption of the cipher text (you need to convert hex text to number) … read more

I have a troubling python question. A company wants to
A company wants to transmit data over the telephone, but it's concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a Python method that will encrypt its data so that the data may be transmitted more securely. Your program should read a four-digit integer entered by the user and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Write your encryptDigits() method in such a way that it accepts the user inputted number as an argument and returns the encrypted one! … read more
