In these questions you will be asked to provide encryption functions. In all cases

assume an alphabet of $26$ characters. Use the interactive cypher tool from the

assessment tools for this week to check your functions. The functions you enter

here must work in that tool $($copy and paste the text$).$

$2\mathrm{.}1$

Create a shift cypher with a non$-$zero shift.

$1.$ Provide an arithmetic expression for the encryption function, E$($X$)$

$2.$ What is the shift of this cypher?

$3.$ Give the encrypted form of the string $$password$.[3]$
