/*
IMPLEMENTATION NOTES FOR USER MANAGEMENT:

Garage uses an administrative RPC interface for managing keys and buckets.
To implement user management, you need to:

1. Install garage-admin client or use HTTP RPC calls
2. Connect to Garage's admin port (typically 3903)
3. Implement the following operations:

   - List keys: GET /v1/key
   - Create key: POST /v1/key
   - Get key info: GET /v1/key?id=<access_key>
   - Delete key: DELETE /v1/key?id=<access_key>
   - Update key: POST /v1/key?id=<access_key>

Example using HTTP client:

import (
	"bytes"
	"encoding/json"
	"net/http"
)

type GarageAdminClient struct {
	baseURL string
	token   string
}

func (g *GarageAdminClient) ListKeys() ([]KeyInfo, error) {
	req, _ := http.NewRequest("GET", g.baseURL+"/v1/key", nil)
	req.Header.Set("Authorization", "Bearer "+g.token)

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		return nil, err
	}
	defer resp.Body.Close()

	var keys []KeyInfo
	json.NewDecoder(resp.Body).Decode(&keys)
	return keys, nil
}
