A barcode is a graphic identifier made of black bars and spaces of varying widths arranged by set encoding rules to express a group of information
A common barcode is a parallel-line pattern of black bars and white spaces with very different reflectance

It is therefore widely used in many fields such as retail distribution, library management, postal services and banking systems

No. MD5 is a one-way digest — you can compare it, never reverse it. So-called "decryption" is a rainbow-table hit.
Salts, random IVs, or a different case or source encoding all change the output. Normalise to UTF-8 before comparing.
Use it for learning and format checks. Generate and store production keys server-side; never paste a live secret into a web page.
