Decrypt the following substitution cipher. Next, create a tool in any language you prefer that will encrypt and decrypt messages using the same key. To complete the challenge, post your code and respond to me in a post below with an encoded message. Good luck!

My solution is is my program encoded. Any character not substituted by the original cipher is to be interpreted as is.
I enjoyed the challenge!
Thanks, limdis

At least you can only replace a teacher in this component https://businessays.net/category/economics/ because all the tips and examples for selecting the topics of your work are always available through this resource, which improves your work every second.
