SPIRE Ciphertrust KMS Plugin

This repository contains an external Key Manager plugin using Thales CipherTrust KMS for SPIRE.

• Thales CipherTrust Manager is an independent 3rd party tool dedicated to efficiently managing keys on behalf of SPIRE.
• It enables the initial enrollment of the SPIRE server architecture.
• CipherTrust KMS provides the Root Key and the keys identifiers.

Demo

Here's a quick demo that shows how this plugin looks when run:

The demo commands can be found on the SPIRE getting started

Get started

Prerequisite

CipherTrust Manager Setup

There are 3 options to setup a CipherTrust Manager instance.

1. Locally using Virtual Box

2. Host on Azure

3. As a service

Quick Start

Before starting, create a running SPIRE deployment and add the following configuration to the agent and server:

Server Configuration

 KeyManager "ciphertrust_kms" {
	plugin_cmd = "/path/to/plugin_cmd"              <- a binary is provided in the bin folder
	plugin_checksum = "sha256 of the plugin binary" <- the hash is provided in the bin folder
	plugin_data = {
         key_metadata_file = "metadata/key-spire-id"
         ctm_url = "https://<CipherTrustManager-instance>"
         username = "<uname>"
         password = "<pwd>"
        }
}

Details of the plugin data

key	type	required	description	default
key_metadata_file	string	Yes	The directory to the spireID metadata, it will be used as the keys unique ID	None
ctm_url	string	Yes	The address to your CipherTrustManager (local or remote)	None
username	string	Yes	Username needed in exchange for a jwt token to access the CTM API	None
password	string	Yes	Password needed in exchange for a jwt token to access the CTM API	None

Directory Configuration

For this plugin to work, all field must be valid and the directory containing the spire metadata must exists prior to running spire.

How it Works

The plugin uses CipherTrust Key Manager to bootstrap the SPIRE Server identity and Signs SVIDs. The plugin operates as follows:

1. Fetches keys from CipherTrust Manager if any
2. Generates keys Pairs for SVIDs bundles (x509 and JWK)
3. Signs SVIDs when needed

Building

To build this plugin on Linux, run make build. The plugin binary will be placed in the bin folder

Important note

• make build will automatically parse the code to detect any anomaly.
• Prior runing the make build, install the staticcheck, gofmt & go vet (go analysis tools) and the goreportcard tool.
• if no anomaly found, the binary and its hash will be generated in the bin folder.

Testing

• Functional plugin testing is located in tests/ciphertrust_spire_plugin_test.go
• Unit testing are located in pkg/ciphertrustkms/tests

Prior to the functional testing make sure you have a valid CipherTrust Manager instance running and update the following variables from tests/ciphertrust_spire_plugin_test.go:

ctmService        = "https://<local/remote IP/name>"
username          = "user"
pwd               = "pwd"

Prior to the unit testing make sure you have a valid CipherTrust Manager instance running and update the following variables from pkg/ciphertrustkms/tests/cihpertrustkms_test.go:

ctmService        = "https://<local/remote IP/name>"
username          = "user"
pwd               = "pwd"
