Keymint Go

A professional, production-ready SDK for integrating with the Keymint API in Go. Provides robust access to all major Keymint features, with idiomatic Go error handling.

Features

• Idiomatic Go: Clean, type-safe API using a Client struct and keymint.New() constructor.
• Comprehensive: Complete API coverage for all Keymint endpoints.
• Consistent error handling: All API errors are returned as *ApiError.
• Machine Identity: Built-in utilities for hardware fingerprinting and stable installation IDs.

Installation

Add the SDK to your project:

go get github.com/keymint-dev/keymint-go

Usage

package main

import (
    "os"
    "fmt"
    "github.com/keymint-dev/keymint-go"
)

func main() {
    apiKey := os.Getenv("KEYMINT_API_KEY")
    productId := os.Getenv("KEYMINT_PRODUCT_ID")

    client, err := keymint.New(apiKey, "")
    if err != nil {
        panic(err)
    }

    // 1. Get a stable, unique ID for this machine
    hostId, err := keymint.GetOrCreateInstallationID("")
    if err != nil {
        panic(err)
    }

    // 2. Create a key authorized only for this machine
    key, err := client.CreateKey(keymint.CreateKeyParams{
        ProductID:    productId,
        AllowedHosts: []string{hostId},
    })
    if err != nil {
        fmt.Printf("Error: %v\n", err)
        return
    }
    
    fmt.Printf("Created Key: %s\n", key.Key)
}

Machine Identity

Keymint provides utilities to uniquely identify machines for node-locking:

• keymint.GetOrCreateInstallationID(storagePath): Recommended. Generates a stable UUID anchored to hardware and persists it to ~/.keymint/installation-id.
• keymint.GetMachineID(): Generates a SHA-256 fingerprint based on BIOS UUID, OS machine ID, and MAC address.
