wolfSSL Intel SGX Support and Testing

Providing Secure, Well-Tested SGX Integration with wolfSSL and wolfCrypt

Did you know that wolfSSL has support for Intel SGX?  Not only do we have support for SGX, but we do continuous integration testing on that support to offer our users a more robust and mature solution. This means that every night a process starts up and runs unit tests on crypto operations in a secure SGX enclave. Here’s a peek at some of the on going tests in action:
