Polynomial-Encryption

This is an encryption algorithm that to encrypt any ascii text

Function

Program has a function f(x) that encrypts text f(x) if a polynomial function that has the form $f(x) = a(b\cdot x + c)^d + e $

g(x) is the inverse function of f(x) that returns the decrypted/original text default a,b,c,d,e values are set in the code but can be changed

Basic Usage

import PolyCryption as PC

x = PC.Encrypt(text)
y = PC.Decrypt(x)

To change coefficents

PC(2,4,5,3,2)
# a,b,c,d,e = 2,4,5,3,2

#or
PC.a = 23
# only a is changed

P(1,1,0,1,0)
#or
P()
# get ascii code of each character

Caution

Although the encryption algorithm works fine, using large coefficents for 'd' will result in large encrypted numbers, therefore I recommend using smaller values for d.

To be more technical you could say the length of each encrypted character is $O(a(b\cdot x + c)^d + e)$

0 can only be used for c and e, giving any other value a 0 will result in an error

Negative numbers can be used for some of the values, however I heavily discourage using it
