Keychain-MDIP CLI User Manual

warning

This feature is currently in the experimental stage of development. Do not use it in production environments or presume it is secure. Expect breaking changes.

The CLI is a Command Line Interface to the Keychain implementation of the MultiDimensional Identity Protocol (MDIP). kc (short for KeyChain) is a script invoked in a unix-like terminal environment (bash, zsh, etc).

Quickstart

The Keychain-MDIP CLI is a user-facing tool used to interact with the MDIP sub-systems and networks.

The Keychain CLI brings together functionality from three important sub-components:

Decentralized Identity (DID) registration and management as defined by W3C DID Core.
Verifiable Credential (VC) credential and management as defined by W3C VC Data Model.
Crypto keys and wallet management.

Installation

Keychain is provided as a set of docker containers and scripts:

From your terminal, download the repository and move to it:

# SSH
git@github.com:KeychainMDIP/kc.git
#HTTPS
https://github.com/KeychainMDIP/kc.git

cd kc

Copy sample.env to .env:
```
cp sample.env .env
```

Edit the KC_NODE_ID and KC_NODE_NAME with unique values. The remaining values will be covered in futher documentation:

.env
# Gatekeeper
KC_DEBUG=false
KC_NODE_NAME=mynode
KC_NODE_ID=mynodeID
KC_GATEKEEPER_DB=json
KC_GATEKEEPER_REGISTRIES=hyperswarm,TBTC,TFTC

...

Run the keychain start script:

# Tied to the shell session:
./start-node

# Daemonized:
./start-node -d

There's also a script to stop Keychain:
```
./stop-node
```

CLI

All the CLI commands are self-documented using the --help flag, or by running kc with no flags:

kc --help

The following examples use a $ to denote the shell prompt:

$ kc

note

Unless you edit your shell's $PATH variable, you need to invoke kc with a ./ prefix to run the script in the current directory:

$ ./kc

Begin by creating a new identity. This will be described in more detail later, but try it now with your own first name:

$ kc create-id yourName
did:mdip:test:z3v8AuaYd1CGfC6PCQDXKyKkbt5kJ4o3h2ABBNPGyGNQfEQ99Ce

The long string returned starting with did will be unique to you. This is your new Decentralized IDentity (DID for short).

Think of a DID as a secure reference. Only the owner of the reference can change what it points to. What makes it decentralized is that anyone can discover what it points to without involving a third party.

Creating a new ID automatically creates a new wallet for your ID, which we will describe next.
