sgx-cpu

A tiny application giving information from your CPU about Intel© SGX support.

This is a Rust rewriting of SGX-hardware that can be run easily using Cargo.

It is based on rust-cpuid library.

Use the ark.intel.com database to list all Intel CPUs that have the SGX feature.

Example

``` $ cargo run SGX CPU information

CPU features

stepping 13 model 14 (extended 9) family 6 (extended 0) ❌ SMX support

Intel SGX capabilities

✅ SGX availability ✅ SGX launch control configuration ✅ SGX 1 support ❌ SGX 2 support ```

getting details using verbose mode

``` $ cargo run -- -v SGX CPU information
