mssun commented on issue #134: Refactoring build time configuration 
URL: https://github.com/apache/incubator-mesatee/issues/134#issuecomment-563921649
 
 
   According to #135, `mr_signer_path` is useless. Here is an update of the build time config file:
   
   ```toml
   # Service provider's root CA certificate to verify clients
   sp_root_ca_cert = { path = "../cert/ca.crt" }
   
   # Intel Attestation Service root CA certificate to verify attestation report
   ias_root_ca_cert = { path = "../cert/AttestationReportSigningCACert.pem" }
   
   # Auditors' public keys to verify their endorsement signatures
   auditor_public_keys = [
       { path = "../auditors/godzilla/godzilla.public.der" },
       { path = "../auditors/optimus_prime/optimus_prime.public.der" },
       { path = "../auditors/albus_dumbledore/albus_dumbledore.public.der"},
   ]
   
   # RPC max message size
   rpc_max_message_size = 409600
   ```
   
   The corresponding generated code will be like this:
   
   ```
   format!(r#"
       pub struct BuildConfig<'a> {{
           pub sp_root_ca_cert: &'a [u8],
           pub ias_root_ca_cert: &'a [u8],
           pub auditor_public_keys: &'a [&'a [u8];{}],
           pub rpc_max_message_size: u64,
       }}
   
       pub static BUILD_CONFIG: BuildConfig<'static> = BuildConfig {{
           sp_root_ca_cert: {},
           ias_root_ca_cert: {},
           auditor_public_keys: {},
           rpc_max_message_size: {},
       }};"#,
           config.auditor_public_keys.len(),
           sp_root_ca_cert,
           ias_root_ca_cert,
           auditor_public_keys,
           config.rpc_max_message_size
       )
   ```
