# Occlum SGX Remote Attestation integrated in TLS connection
Steps to test the project:
The MRSIGNER of the `example/signing_key.pem` is hardcoded in the enclave code:
```
occlum-cargo build --example server --features="occlum,actix-web"
strip -s target/x86_64-unknown-linux-musl/debug/examples/server
./build_server.sh
6871A831CED408CD99F0ED31587CC2B5C728C99D4A0A1ADF2F0C5574EBBB00DC
```
occlum-cargo build --example client --features="occlum,reqwest"
strip -s target/x86_64-unknown-linux-musl/debug/examples/client
You can generate your own signing key. Just use the following command:
```
openssl genrsa -3 -out signing_key.pem 3072
```
To get the MRSIGNER of the key, compile [this project](https://github.com/intel/sgx-ra-sample)
and use the following command:
```
./mrsigner signing_key.pem
```
## Running Examples
Before running make sure you have installed the Occlum and the SGX driver.
You should also have the Occlum Rust toolchain installed to get `occlum-cargo`.
To test the project just run client and server scripts in different terminals:
```
./build_server.sh
./build_client.sh
```
