Enarx Keep Loader

enarx-keepldr

This crate provides the enarx-keepldr executable which loads static-pie binaries into an Enarx Keep - that is a hardware isolated environment using technologies such as Intel SGX or AMD SEV.

Building

Please see BUILD.md for instructions.

Run Tests

$ cargo test

Build and Run an Application

$ cat > test.c <<EOF
#include <stdio.h>

int main() {
    printf("Hello World!\n");
    return 0;
}
EOF

$ musl-gcc -static-pie -fPIC -o test test.c
$ target/debug/enarx-keepldr exec ./test
Hello World!

Select a Different Backend

enarx-keepldr exec will probe the machine it is running on in an attempt to deduce an appropriate deployment backend unless that target is already specified in an environment variable called ENARX_BACKEND.

To see what backends are supported on your system, run:

$ target/debug/enarx-keepldr info

To manually select a backend, set the ENARX_BACKEND environment variable:

$ ENARX_BACKEND=sgx target/debug/enarx-keepldr exec ./test

Note that some backends are conditionally compiled. They can all be compiled in like so:

$ cargo build --all-features

Or specific backends can be compiled in:

$ cargo build --features=backend-sgx,backend-kvm
