Job Description

I have a file that I want to know how it was encrypted and develop an application that can encode it and decode it back.
I am attaching the file here, see if you can do it, because I will ask you what the file means because I already know how it looks like.
So, if you are sure of yourself and you know you can give me what can decode and encode the file, apply for this job.

Skills: software-development, data-collection, data-conversion
