Install Certifier (Ubuntu 20.04)

Setup Environment variables

git clone https://github.com/vmware-research/certifier-framework-for-confidential-computing.git export CERTIFIER=certifier-framework-for-confidential-computing export CERTIFIER_PROTOTYPE=$CERTIFIER export EXAMPLE_DIR=$CERTIFIER_PROTOTYPE/sample_app

Install Dependencies

sudo apt install libgtest-dev libgflags-dev

We note that the versioning of protobuf and golang matters. One shall not use the distribution directly apt-ed from Ubuntu.

Install the latest protobuf from source by

sudo apt install autoconf automake libtool curl make g++ unzip
git clone https://github.com/protocolbuffers/protobuf.git
cd protobuf
git submodule update --init --recursive
./autogen.sh && ./configure
 make -j$(nproc)  &&  sudo make install
 sudo ldconfig # refresh shared library cache.

the detailed installation procedure can be found https://github.com/protocolbuffers/protobuf/blob/main/src/README.md.

Install the latest golang by

sudo apt install wget 
wget https://go.dev/dl/go1.18.4.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.18.4.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin && export PATH=$PATH:$(go env GOPATH)/bin
rm go1.18.4.linux-amd64.tar.gz

The protobuf compiler(protoc) for golang is installed by

go get github.com/golang/protobuf/proto
go get google.golang.org/protobuf/cmd/protoc-gen-go

Ensure OpenSSL library and OpenSSL headers are installed or install by

sudo apt install openssl
sudo apt install libssl-dev

Current tests on Ubuntu are with OpenSSL 1.1.1f.

Compile Certifier Library

The certifier library can be compiled by

 cd $CERTIFIER/src
 make -f certifier.mak

cd $CERTIFIER/utilities
make -f cert_utility.mak
make -f policy_utilities.mak

Build the Certifier Service

  1. Compile the protobuf required by certifier service by
 cd $CERTIFIER/certifier_service/certprotos
 protoc --go_opt=paths=source_relative --go_out=. --go_opt=Mcertifier.proto= ./certifier.proto
  1. Install the certifier as go library by
go install  github.com/jlmucb/crypto@latest
# TODO: this is a workaround to an existing path issue 
mkdir -p $(go env GOPATH)/src/github.com/jlmucb/crypto/v2
sudo cp -r $CERTIFIER $(go env GOPATH)/src/github.com/jlmucb/crypto/v2
  1. Build the simple server
 cd $CERTIFIER/certifier_service
 go build simpleserver.go

If showing error of go.mod not found, run go env -w GO111MODULE=off before building.

Run sample_app

To run sample application, follow the README in sample_app or directly run

cd $EXAMPLE_DIR
chmod +x ./script
./script
