Access Key Decoder - JS

A simple project to create an access key decoder for brazilian invoices.

1 - How to use

1. Install Node.js on your machine;
2. Run node ./src/index.js, then you'll be asked for an access key;
3. Paste the access key and type Enter;
4. The program will decode and tell you the state, the model of the access key and show the Access Key entity;
5. Then it'll ask for a new access key (recursive loop);
6. You can leave by typing quit, exit, leave, stop or just press Ctrl+C.

Have fun!
