Need Boosting service from wood rank to grandmaster

Issue with creating QR codes for the nhs travel pass or just a EU one in general, using several sources of information and posts on github. either way I can't output a QR code after trying several things so thought I'd post about it to see if I can get some help, would be much appreciated.

Can someone give me an idea on what software they are using to get these QR codes asap please.

Here's what I've looked through to try and get this to work but can't find enough nor experienced enough to make it happen, need someone to show me the road.

@Cifinta Just to understand your request correct: you want to generate and sign a DCC structure beginning from the scratch?

If yes, you should start here:

https://github.com/ehn-dcc-development/hcert-kotlin

A very good library for generating DCCs. How to use it's in the readme. Works as well for JAVA. But please keep in mind, that you can not proper sign a DCC without a valid document signer certificate from your country.
