Simple shift cipher
WebbSubstitution of single letters separately—simple substitution—can be demonstrated by writing out the alphabet in some order to represent the substitution.This is termed a substitution alphabet.The cipher alphabet may be shifted or reversed (creating the Caesar and Atbash ciphers, respectively) or scrambled in a more complex fashion, in which case … http://www.crypticwoodworks.com/basic-shift-cipher

Your goal is to create a function that allows a user to input a string and a shift index and outputs the shifted cypher-text as a string. The shift index is an integer that tells the encryption method how many letters to shift each letter in the message forward.
WebbShift ciphers are child’s play, simply keep your seed phrase secure, add a pass phrase. I mean, if someone got a hold of the paper, they'll still figure it out if they really wanted to. …
