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. IN C ++ please
Test your program with the following plain text:
The user should be able to input there own plain text file very important no hard code please
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.

Source code of the encryption program.
A screen shot showing the encryption with a 5 byte key.
The cipher text from the encryption, saved in hexadecimal (you may want
to use the "hex" output manipulator)
Source code of the decryption program.
A screen shot showing the decryption of the cipher text with the same 5 byte key.
The plaintext from the decryption of the cipher text (you need to convert hex text
to number) Put everything in one PDF or WORD file. Do not zip.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx, fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx, fs) does automatic scaling and then calls sound(xx, fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2

Between 1932 and 1938, chester carlson developed a process that enabled a "picture" of a document to be taken and then have it reproduced on another
