Implement this key cipher
Use the algorithm (explained in the Algorithm section) to implement a certain cipher.
The program must read input from STDIN or the closest available equivalent, use the algorithm to generate the ciphertext and a key.
The ciphertext and the key will be written to STDOUT or the closest available equivalent. Any format is allowed, as long as it outputs the ciphertext and the key.
Convert the characters in the string into the respective ASCII values. For example:
Hello -> 72 101 108 108 111
Next, you will need to generate a key as long as the string with random numbers in the range of 0-9.
Hello -> 62841
Add the integers in the random number sequence to the ASCII values of the string. In the above examples, 72 would become 78, and 101 would become 104.
72 + 6 = 78, 101 + 2 = 103, 108 + 8 = 116, etc
Next, convert the new values back to characters. In the above examples, the text
Hello has become
(These are simply examples of what the output might look like. The output can and will vary.)
Hello World Lfrlu)_supg 41606984343

- You can assume that the input will only contain characters in the range a-z, A-Z, and spaces.
- Submissions must be full programs or functions.
- Submissions will be scored in bytes.
- Standard loopholes are forbidden.
- This is code-golf, so the shortest code wins.
(This is one of my first challenges, if there's something wrong with it, feel free to tell me how I could improve it.)
