Verification of the signature always false

I have updated the key list with the latest available, but in the console the result of "isValid" is always false with any green pass entered.

Are other operations necessary to make everything work?

createqr generates unrecognizable code for decodeqr

The HC1 prefixes of your sample images do not result in the same image as the corresponding sample images and can not be read by decodeqr.

Dutch qr decode failed. It's using a custom base45 encryption

Hi.. I cannot decode a dutch QR code with it as it uses a custom base45 variant.

You can read more about it here: https://www.bartwolff.com/Blog/2021/08/21/decoding-the-dutch-domestic-coronacheck-qr-code

Is there a possibility to add something so that dutch codes also work?

Thanks in advance!
