Prerequisites:

1. Make sure you've installed the SGX software stack (driver, PSW and SDK) and tested the installation by running sample apps.

Following command will check whether the SGX driver was loaded:

$ sudo lsmod | grep isgx

The above command should display 'isgx'.

Following command will check whether the AESM background service is loaded and running:

$ sudo service aemsd status

If it's not running, please run it with:

$ sudo service aesmd start or $ sudo service aemsd restart

NOTE: If AESM service fails to run even after the above, then it means the SGX driver was not loaded. Please re-check whether SGX driver was loaded.

2. Source environment for using SGX tools:

$ source /environment

For example, if you installed SGX SDK in your home directory, then the command would be:

$ source ~/sgxsdk/environment

3. The sample uses OpenSSL libraries to encode the output files. Install libssl-dev:

$ sudo apt install libssl-dev

4. Compile the demo

   If you have hardware support for Intel(R) SGX:

   (4a) make

   If you would rather use the simulator:

   (4b) make SGX_MODE=sim

5. Run the pure-software simulation of the sample (after making it executable):

$ chmod +x run_demo_*.sh $ ./run_demo_openssl.sh

6. Run the same flow, using an SGX enclave:

./run_demo_sgx.sh
