Austrian cash register fiscalization

Please be aware this repository is still under active development if you plan to use it in a production environment.

In Austria the fiscalization process is called Registrierkassensicherheitsverordnung (RKSV).

In this repository, we use about PrimeSign online sign feature (via Cryptas).

What we took from them is a simple service which accepts RKSV payloads and then gives you a properly encrypted & signed response. Worry free and fewer complications with signing receipts. So what you need for this package to work is the following:

• PHP
• PrimeSign remote signing SaaS service for RKSV (for example: we took this one)

How it works

First you have to create a receipt with data which will be used for signing:

Using the created ReceiptData, pass it on to ReceiptSigner with other PrimeSign arguments and call the desired method for signing:

Getting the result of signing:

Beside normal signer, you can also call:

• cancel receipt signature $receiptSigner->cancelSign();
• training receipt signature $receiptSigner->trainingSign();

Null sign will use the cashBoxId for generating chain value. This is the first receipt you create when initializing receipt sequences. The package will accept items, but will ignore them and overwrite with zero values.

TODO and general

• implement proper unit tests which should cover hashing, encryption, qr code generation and other major-impact topics
• implement proper unit tests for entire process - normal sign, training sign and cancel sign + chaining of all those
• implement command which will gneerate the null reciept that can also be used
• documentation on code and RKSV process
• complete remove sign service factory and implement all logic inside a SignService class.
• revise all exeptions and poperly test them via unit tests
• revise all validators and see on what are needed and which can be added
• expand on info on how to incorporate into other peojects (if needed, discuss)

Updating this package works like this:

• commit
• push to master
• create tag
• push tag
• webhook is triggered to send tag to PHP packages repo
• convert tag to release - example github action is on other repos

Other repos using this one will need to update their packages entry to use latest version.
