S32G3 HSE x.509 certificate signature verification with root certificate and extract public key.

[Subramanya]

Hello Team,

looking for below inputs, how it can be achieved in S32Gx devices via HSE service. I see these examples are not covered in HSE Demo application for S32G2/3 devices:

1. Verify x.509 certificate via another certificate/key.
2. Extract public key from x.509 certificate.

An external parser is required for x.509 certificate parsing or do we have a HSE service to do this x.509 parsing? Kindly provide the hint/ code snippet for the same for ECC/RSA certificate.

Thanks

When I look at the RTD of crypto, I find that the certificate functions all return CRYPTO_RET_NOT_SUPPORTED, Does this mean that HSE cannot parse the certificate ? ,If so ,how can I do it?
