Static Library: Building libwolfssl.sgx.static.lib.a for use with SGX Enclaves
Requirements:
This code was created to use Intel's SGX hardware. It is expected that the user has gone through the steps of both turning on the hardware in bios if needed and has installed the necesary software from Intel to make use of the hardware. (https://software.intel.com/en-us/sgx) If these steps have not been done then it is expected that the user is familure with simiulation software being used in place of hardware.
Overview and Build:
This project creates a static library to then link with Enclaves. A simple example of an Enclave linking to the created wolfSSL library can be found in wolfssl-examples on github. This project has been tested with gcc 5.4.0 on Ubuntu 16.04.
To create the static library, simply call make:
make -f sgx_t_static.mk all
This will create a local static library, libwolfssl.sgx.static.lib.a, that can be linked with SGX enclaves to access wolfSSL APIs using SGX hardware.
Limitations: Single Threaded (multiple threaded applications have not been tested) AES-NI use with SGX has not been added in yet
