How to create eIDAS certificate with QWAC and QSealC profiles (PSD2 specific attributes) for testing

Question

I want to create a eIDAS certificate with QWAC and QSealC profiles with PSD2 specific attributes as mentioned in the doc. Please help me, this is just for testing purposes.<

Answer 1

For me the simplest option was to use OpenSSL command line utility:

openssl req -new -config qwac.conf -keyout qwac.key -out qwac.csr && openssl x509 -req -in qwac.csr -signkey qwac.key -out qwac.crt

qwac.conf is openssl config where you have to set PSD2 specific fields as described here. Configs for QWAC and QSealC can be exactly the same, just need to run command twice.
