vetKeys API demo
Advanced
Tutorial
Overview
This demo provides a canister (src/system_api) that offers the proposed vetKD system API, implemented demonstration, testing, and initial development purposes. We stress that it does not offer security yet as no threshold cryptography is used yet to secure the key.
This demo uses files found in this repository.
Prerequisites
- Download and install the IC SDK package as described in the installing the IC SDK page.
- Download and install npm.
- Download and install git.
Step 1: Begin by cloning the Github repository containing this project:
- Motoko
- rust
git clone https://github.com/dfinity/examples/
cd examples/motoko/vetkd
git clone https://github.com/dfinity/examples/
cd examples/rust/vetkd
Step 2: Then, start a local instance of the Internet Computer:
dfx start --clean --background
Step 3: Ensure the dfx uses the canister IDs that are hard-coded in the source code:
dfx canister create system_api --specified-id s55qq-oqaaa-aaaaa-aaakq-cai
Without this, the dfx may use different canister IDs for the system_api and app_backend canisters.
Step 4: Ensure that the required node modules are available in your project directory:
npm install
Step 5: Register, build and deploy the project:
dfx deploy
This command should finish successfully with output similar to the following one:
Deployed canisters.
