Answers to Questions

How to encrypt using Barcode 128 cipher?

Encryption uses the EAN-128 barcode coding standard which includes 3 encoding tables: the 128A, 128B and 128C codes.

The barcode therefore includes alternate black and white lines of variable width (between 1 and 4).

The code starts with Start and ends with End, between are the characters to encrypt each represented by 6 bars (3 blacks and 3 whites).

If you want to code DCODE with 128B.

You have to code Start, D, C, O, D, E, End

211214,112313,131321,133121,112313,132113,2331112

Normally the code 128 includes a checksum (modulo 103href), here it is ignored.

How to decrypt Barcode 128 cipher?

Decryption requires performing a simple reading of the bar according to EAN-128 standard.

Many app for smartphones facilitate this work.

If you have the message 2112141123131313211331211123131321132331112

You can check the first 6 digits (corresponding to the first 3 black bars and 3 white bars), here 211214 that stands for 128B Code. Then split each 6 characters, before translating them.

The message contained in the bar code is dCode.

How to recognize 128 Barcode?

The barcode may have a conventional graphical form (black and white lines) or a binary equivalent (of 0 to vacuum and 1 white bars) or a base 4 code (1,2,3 and 4 for the size of the bar, alternating black and white).

The bar code may have a variable length. It begins (usually) by Start and ends with the character End (see table).

What is the difference between codes 128A, 128B and 128C?

Coding table 128A has ASCIIhref characters from 00 to 95.

Coding table 128B has ASCIIhref characters from 32 to 127.

Coding table 128C has all numeric values from 00 to 99.
