rust-sgx-sdk-playground's Introduction

Hello World to rust-sgx-sdk

Docker playground

All examples can be built and run in simulation mode within docker containers provided by the official repository.

To speed up daily development, the play.sh can be used to bootstrap a ready container for you, with a simple command

# this will mount ${PWD} into the /workspace directory within the container
./scripts/play.sh

Preparation

Pull in the official incubator-teaclave-sgx-sdk submodule
```
git submodule update --init 
```

Build

# as many as you want
mkdir build 
cd build
# default is SIM mode. For hardware mode, use 'cmake -DCMAKE_BUILD_TYPE=Release ..'
cmake ..
make -j

Run

# the hello-world example
make run-hello-world

Examples

The mitigration towards [email protected] is WIP

Project	Description
crypto	cryptographic primitives
hello-world	hello-world example with app built with cargo build script
hello-world-debug	hello-world example demonstrating `sgx-gdb`-based debugging and `sgx_emmt`-based memory measurement
hello-world-i-dont-like	hello-world example
https-client	a https client running within enclaves
massive-stdio	test the maximum buffer size of arguments in ecalls/ocalls
mini-ecdh	demonstrate how to do ECDH
prost-based-protobuf	a demo of using protobuf implemented by the prost library
tls-server	a TLS server running within enclaves

FYI

In the hardware mode, please employ the specific rust toolchain tagged by nightly-2019-08-01
```
rustup install nightly-2019-08-01
rustup default nightly-2019-08-01
```
For errors of pattern as follow, it's because dependencies bring std into the no_std environment. As for how to address this, check apache/incubator-teaclave-sgx-sdk#31
```
error: duplicate lang item in crate `sgx_tstd`: `f32_runtime`.

= note: first defined in crate `std`.
```
When generating the trusted and untrusted bridges, projects would need to search rust-sgx-sdk/edl for extra edl files. We should keep the these edl synchronized to the version of rust-sgx-sdk in use.
libcompiler-rt-patch.a is to address a potential bug, so it's optional.

Git Tips

delete submodules

git submodule deinit ${path-to-submodule}
git rm --cached ${path-to-submodule}
