Despite concerns that its phones may be tapped, a corporation wants to send data over the phone. It transmits four-digit integers. To secure data transmission, it wants you to develop a script to encrypt it. The user enters a four-digit number in a prompt dialogue, and your script encrypts it: Replace each digit with (the sum of that digit plus 7) modulus 10. Then switch the first digit with the third and the second with the fourth. Display the encrypted integer in HTML5. JavaScript and HTML

Encode the number using the given public key. Encode the number M = 14 using the public key n = 77 and e = 13. Assume you are encoding the number using the RSA cryptosystem. Note: You can use the Modular Exponentiation calculator to help with the calculation. a 46 (mod 77), encoded number = 46 47 (mod 77), encoded number = 47 48 (mod 77), encoded number = 48 d. 49 (mod 77), encoded number = 49
PYTHON!!! A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right. For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation. Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input. The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position. The script shiftRight performs the inverse operation. Each script prints the resulting string. An example of shiftLeft.py input and output is shown below: Enter a string of bits: Hello world! ello world!H An example of shiftRight.py input and output is shown below: Enter a string of bits: Hello world! !Hello world The program produces correct output for given input. Test Case: SL Hello world! Input: Hello world! Results: ello world!H Test…
Samething this is not a graded question it's all in python.
Passwords that are created by users are usually very simple and easy to guess. Create a Python program that takes a simpler pswrd + makes it stronger by taking characters using the rules below, and by appending "!" to the ending of the input string. i becomes 1 a becomes @ m becomes M B becomes 8 s becomes $ Example: If the input is: mypassword the output is: Myp@$$word! Hint: Python strings are immutable, but support string concatenation. Store and build the stronger password in the given password variable This is what I have so far.... word = input()password = ''
On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fo* r, where n is the distance (number of keys) from that key, and r is 21/12) Given an initial key frequency, output that frequency and the next 3 higher key frequencies. Output each floating-point value with two digits after the decimal point, then the units ("Hz"), then a newline, using the following statement: printf("$0.21f Hz\n", yourValue); Ex: If the input is: 440.0 (which is the A key near the middle of a piano keyboard), the output is: 440.00 Hz 466.16 Hz 493.88 Hz 523.25 Hz Note: To compute the next 3 higher key frequencies, use one statement to computer = 2(1/12) using the pow function (remember to include the math library). Then use that r in subsequent statements that use the formula f = f0 *r¹ with n being 1, 2, and finally 3. O Run v main.c 1 2 3 int main(void) { #include Reset Lab Tutorial Ⓡ
