I am new to this platform and I am able to do registration and download Permission Artefact. I was trying to verify the signed data from the artefact with signature and by extracting public key from x509 certificate.
I am using c++ and openssl for verification of code. The signed data is taken in a char pointer before verification process.
Also the signing and verification is working fine if the data is signed at my end using x509 Certificate.
Can you please share your side of implementation of x509 certificate verification using openssl using c.
