# sgx-cpu

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

This is a Rust rewriting of [`SGX-hardware`](https://github.com/ayeks/SGX-hardware) that can be run easily using `Cargo`.

It is based on [`rust-cpuid`](https://github.com/gz/rust-cpuid) library.

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

## Installation

```
cargo install sgx-cpu
```

Usage
```
sgx-cpu
```

## Examples

```
$ sgx-cpu
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
```
