In my application, I need to check the list and attribute values in the accepted certificate under “issuer”. For this I plane to use “mbedtls_x509_dn_gets”. For one of the attributes “Organization Identifier - (0x61)”, the function returned “??” - unknown attribute.
How do I proceed? Should I add the attribute to the code?
Is it possible to use “issuer_raw” for this check? Does the “issue_raw” value change with the same number of attribute values but changed their order?
