## Simple GRPC protocol for the demo
|
||||||
|
|
||||||
#### Executing the demo in Occlum
|
* Server side, holds a [`json file`](./secret_config.json) including secret name and the secret's base64 encoded string.
|
||||||
|
|
||||||
The following command will download the gRPC source code and apply the ra-tls patches, then build gRPC source code and demo.
|
* Client side, request the secret by the secret name.
|
||||||
|
|
||||||
|
## Example libraries/executables in the demo
|
||||||
|
|
||||||
|
* libhw_grpc_proto.so
|
||||||
|
* libgrpc_ratls_client.so
|
||||||
|
* libgrpc_ratls_server.so
|
||||||
|
* client
|
||||||
|
* server
|
||||||
|
|
||||||
|
### APIs defined for sample server and client
|
||||||
|
|
||||||
|
* Server
|
||||||
```
|
```
|
||||||
./prepare_and_build_package.sh
|
int gr_start_server(
|
||||||
|
const char *server_addr, // grpc server address+port, such as "localhost:50051"
|
||||||
|
const char *config_json, // ratls handshake config json file
|
||||||
|
const char *secret_json // secret config json file
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
* Client
|
||||||
|
```
|
||||||
|
int gr_client_get_secret(
|
||||||
|
const char *server_addr, // grpc server address+port, such as "localhost:50051"
|
||||||
|
const char *config_json, // ratls handshake config json file
|
||||||
|
const char *name, // secret name to be requested
|
||||||
|
const char *secret_file // secret file to be saved
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
All source could be found on [`example`](./grpc/v1.38.1/examples/cpp/ratls/)
|
||||||
|
|
||||||
|
|
||||||
|
## Executing the demo in Occlum
|
||||||
|
|
||||||
|
The following command will download prerequisite source and the gRPC source code.
|
||||||
|
```
|
||||||
|
./download_and_prepare.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
The following command will patch the gRPC source code and do the build and install.
|
||||||
|
```
|
||||||
|
./build_and_install.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
If musl-libc version is expected.
|
||||||
|
```
|
||||||
|
./build_and_install.sh musl
|
||||||
```
|
```
|
||||||
|
|
||||||
The following command will generate the client and server occlum images. It automatically parses the mr_enclave and mr_signer of the client, and write the value into dynamic_config.json. If you want to verify the other measurements of client, please modify the dynamic_config.json before run the script.

```
|

|
|
||||||
***Note:*** 1. The demo runs in the same machine by default. If you want to run server and client in different machines. Please modify the examples/cpp/ratls.

|

// Two APIs provided:
|
|
||||||
//
|
|
||||||
// 1) Simple functional api `getarg(...)`.
|
|
||||||
// - No initialization required: (argc, argv) pair automatically retrieved.
|
|
||||||
// - First argument is default option value, then all option indentifiers follow.
|
|
||||||
//
|
|
||||||
// int main() {
|
|
||||||
// bool help = getarg( false, "-h", "--help", "-?" );
|
|
||||||
// int version = getarg( 0, "-v", "--version", "--show-version" );
|

// int depth = getarg( 1, "-d", "--depth", "--max-depth");
|

||||||
// std::string file = getarg( "", "-f", "--file" );
|
|
||||||
// [...]
|
|
||||||
// }
|
|

//
|
|
||||||
// 2) Simple OOP map-based api `getopt class`. Initialization (argc, argv) pair required.
|
|
||||||
//
|
|
||||||
// This getopt class is a std::map replacement where key/value are std::string types.
|
|
||||||
// Given invokation './app.out --user=me --pass=123 -h' this class delivers not only:
|
|
||||||
// map[0] = "./app.out", map[1] = "--user=me", map[2]="--pass=123", map[3]='-h'
|
|
||||||
// but also, map["--user"]="me", map["--pass"]="123" and also, map["-h"]=true
|
|
||||||
//
|
|
||||||
// Additional API:
|
|
||||||
// - .cmdline() for a print app invokation string
|
|
||||||
// - .str() for pretty map printing
|
|
||||||
// - .size() number of arguments (equivalent to argc), rather than std::map.size()
|
|
||||||
//
|
|
||||||
// int main( int argc, const char **argv ) {
|
|
||||||
// getopt args( argc, argv );
|
|
||||||
// if( args.has("-h") || args.has("--help") || args.has("-?") || args.size() == 1 ) {

// std::cout << args["0"] << " [-?|-h|--help] [-v|--version] [--depth=number]" << std::endl;
