Lab Name

crypto-lib

Short Description

A lab for experimentation on creating shared cryptography modules for cross-project collaboration

Scope of Lab

The purpose of this lab is to serve as an initial launching point for what will hopefully become a shared Hyperledger cryptography library. We aim to use this lab to set up a code base and experiment with integrating cryptographic protocols between projects.

See: https://docs.google.com/document/d/1JtFT5L-82egj6shgGXzTsNAg6_UHuMheKfsst6NS_Xo/edit?usp=sharing for more details.

Before you Continue

If you haven't done so already, please visit the main resource for all things "Indy" to get acquainted with the code base, helpful resources, and up-to-date information: Hyperledger Wiki-Indy.

Crypto Lib

This is the shared crypto library for Hyperledger components.

Hyperledger provides a distributed-ledger-based foundation for self-sovereign identity.

The major artifacts of the Crypto Lib are:

  • С-callable library interface
  • Rust сrate

All bugs, stories, and backlog for this project are managed through Hyperledger's Jira in project IS (note that regular Indy tickets are in the INDY project instead...). Also, join us on Jira's Rocket.Chat at #indy-sdk to discuss.

Building Crypto-Lib

  1. Install xcode command line tools
xcode-select --install
  1. Install Rust and rustup (https://www.rust-lang.org/install.html).
  2. Install Libsodium
    • For Mac OS X
brew install libsodium

or to build it from scratch

brew install autoconf
brew install automake
git clone [email protected]:jedisct1/libsodium.git
cd libsodium
./autoconf
./configure
make
sudo make install

  1. Checkout and build the library:

    git clone https://github.com/hyperledger-labs/crypto-lib.git
cd ./crypto-lib/libhl-crypto
cargo build
cd ..

  2. Run tests

    cd libhl-crypto
cargo test

Note: By default cargo build produce debug artifacts with a large amount of run-time checks. It's good for development, but this build can be in 100+ times slower for some math calculation. If you would like to analyse CPU performance of libindy-crypto for your use case, you have to use release artifacts (cargo build --release).

Windows build dependency

System OpenSSL library is required.

  • Download the prebuilt dependencies here
  • Extract them into the folder C:\BIN\x64

It really doesn't matter where you put these as long as you remember where so you can set the environment variables to this path

  • Point path to this directory using environment variables:
    • set INDY_CRYPTO_PREBUILT_DEPS_DIR=C:\BIN\x64
    • set OPENSSL_DIR=C:\BIN\x64

Documentation

Project documentation is available via sphinx. Install sphinx:

pip install -U Sphinx

Build the project docs:

cd docs/
make html

API documentation is now available as rust doc in code. See:

Binaries

Note: Binaries creation is in progress now!!!

Builded binaries can be downloaded from https://repo.sovrin.org:

  • sdk/lib/apt/xenial/{master,stable,rc} - Ubuntu deb packages
  • windows/libindy_crypto/{master,stable,rc} - Windows zip-archive with all required DLLs (include libindy itself) and headers
  • ios/libindy_crypto/stable/ - Pods for iOS
  • rhel/libindy_crypto/{master,stable,rc} - RHEL rpms

Also Ubuntu deb packages can be installed from APT repository:

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 68DB5E88
sudo add-apt-repository "deb https://repo.sovrin.org/sdk/deb xenial stable"
sudo apt-get update
sudo apt-get install -y libindy-crypto
