[mbed-tls] Re: extract AKI info from cert via mbedtls ?

Hello Danny,

What is the version of mbed TLS you are using?

I think latest version expose AKI with

mbedtls_x509_authority authority_key_id;

as a member of the mbedtls_x509_crt class.

Best regards,

François

Hi,

How can I extract the AKI (Authority Key Identifier) from a certificate using mbedtls ?

I could parse the certificate file itself, I guess, but isn't that what mbedtls does?

Thanks,

Danny
