Trusted Build Process signatures

This repository contains gitian signatures for Litecoin. It should be updated on each release. Random members of the public are encouraged to participate in this process in order to better secure the integrity of the Gitian builds.

Generating Gitian Sigs

Checkout litecoin, gitian-builder and gitian.sigs.ltc

mkdir workdir
cd workdir
git clone https://github.com/devrandom/gitian-builder.git
git clone https://github.com/litecoin-project/litecoin.git
git clone https://github.com/litecoin-project/gitian.sigs.ltc.git

Create Gitian Base VM Images

cd ./gitian-builder
    bin/make-base-vm --arch i386
    bin/make-base-vm --arch amd64
    bin/make-base-vm --arch amd64 --suite precise

Fetch and build inputs: (first time, zor when dependency versions change)

Choose your GPG identity and git tag VERSION that you wish to build.

export SIGNER=(your gitian key, ie bluematt, sipa, etc)
export VERSION=0.8.0

Build litecoind and litecoin-qt on Linux32, Linux64, and Win32:

./bin/gbuild --commit litecoin=v${VERSION} ../litecoin/contrib/gitian-descriptors/gitian.yml
./bin/gsign --signer $SIGNER --release ${VERSION} --destination ../gitian.sigs.ltc/ ../litecoin/contrib/gitian-descriptors/gitian.yml
./bin/gbuild --commit litecoin=v${VERSION} ../litecoin/contrib/gitian-descriptors/gitian-win32.yml
./bin/gsign --signer $SIGNER --release ${VERSION}-win32 --destination ../gitian.sigs.ltc/ ../litecoin/contrib/gitian-descriptors/gitian-win32.yml

It is customary to rename your directories in gitian.sigs.ltc to match your github username. Submit a Pull Request against this repo. If you are uncertain, please see previous commits for examples.
