A alogrthim for encrypting and decrypting text by key using numbers.
A text can be converted to no. like 1-4564-43 and it have to unlock by a key that is inside the no. generally when plain text and key is placed on this algos text get converted to no [for ' ' = 1 , '1' = 2 on and on] and appending '-' after each no. In key converting to no is different as compared with plain text it just mutiplied the no on character '-'. Then again no. text is split by - and each no is multiplied by key again we repack it and we get brand new no. on decrypting it's just opposite
Code is on git
