Simple ASCII encoder and decoder using Python

I’m skipping a little bit ahead in the chapters because I think this is pretty cool.

Ever want to send hidden messages to somebody, but don’t know how? Here’s a simple ASCII encoder and decoder for you. You can modify this any way you want, but sure that you change both the encoder and the decoder.

A basic rundown of the program is such:
The program takes the letters of whatever message you are encoding and turns it into the ASCII equivalent. You can find the complete table here ASCII Table . The encoded message you get out of it will just be numbers. Whoever you send the numbers to puts the message into the decoder and that turns the numbers back into letters! Awesome right? Simple, easy, and most normal people don’t know it.

If you want to modify it to be a little bit harder for somebody to catch onto, you could take the numbers that you’re encoding and add 2 or multiply by 7. Remember in the encoder you would have to do the opposite to make the message come out right. Be careful dividing in the encoder, the numbers might not come out right. If you wanted to be really sneaky, You could even do the mod of the number and then find out the numbers equivalent to the mod and have the decode print out what the different messages could be based on the mod. That actually sounds like fun, I might try that sometime 🙂

Remember, my indents are not correct do to the layout of the page. It should look like what’s in the pictures.

Encoder:

def main():
    mess = input("Message: ")

    for ch in mess:
        print(ord(ch), end = " ")
    print()

main()

Decoder:

def main():

    for i in range(10000):
        inString = input("Code: ")

        chars = []
        for numStr in inString.split():
            codeNum = eval(numStr)
            chars.append(chr(codeNum))

        message = "".join(chars)

        print(message)

main()

Here’s a little bit of extra information. Run it through your decoder to find out what it says 🙂
