Tinfoil Go Client

For complete documentation, see the Go SDK documentation.

Installation

Add the Tinfoil SDK to your project:

go get github.com/tinfoilsh/tinfoil-go

Quick Start

The Tinfoil Go client is a wrapper around the OpenAI Go client v3 and provides secure communication with Tinfoil enclaves. It has the same API as the OpenAI client, with additional security features:

• Automatic attestation validation to ensure enclave integrity verification
• Supports Encrypted HTTP Body Protocol to provide direct-to-enclave encrypted communication with attested public keys
• Supports a fallback mode with TLS certificate pinning using attested certificates to provide direct-to-enclave encrypted communication over TLS

package main

import (
	"context"
	"fmt"
	"log"

    "github.com/openai/openai-go/v3"
    "github.com/openai/openai-go/v3/option"
	"github.com/tinfoilsh/tinfoil-go"
)

func main() {
	// Create a client
	client, err := tinfoil.NewClient(
		option.WithAPIKey("<YOUR_API_KEY>"),
	)
	if err != nil {
		log.Fatalf("Failed to create client: %v", err)
	}

	// Make requests using the OpenAI client API
	// Note: enclave verification and direct-to-enclave encryption happens automatically
	chatCompletion, err := client.Chat.Completions.New(context.TODO(), openai.ChatCompletionNewParams{
		Messages: []openai.ChatCompletionMessageParamUnion{
			openai.UserMessage("Say this is a test"),
		},
		Model: "llama3-3-70b", // see https://docs.tinfoil.sh/models/catalog for supported models
	})

	if err != nil {
		log.Fatalf("Chat completion error: %v", err)
	}

	fmt.Println(chatCompletion.Choices[0].Message.Content)
}

Usage

// 1. Create a client
client, err := tinfoil.NewClient(
	option.WithAPIKey(os.Getenv("TINFOIL_API_KEY")),
)
if err != nil {
	log.Printf("Failed to create client: %v", err)
	return
}

// 2. Use client as you would openai.Client
// see https://pkg.go.dev/github.com/openai/openai-go/v3 for API documentation

Advanced Functionality

// Create a secure client with explicit enclave and repo parameters
client, err := tinfoil.NewClientWithParams(enclave, repo)
if err != nil {
	return fmt.Errorf("Failed to create client: %v", err)
}

// For direct HTTP access, use the underlying HTTPClient
httpClient := client.HTTPClient()
endpoint := fmt.Sprintf("https://%s/health", enclave)
resp, err := httpClient.Get(endpoint)
if err != nil {
	return fmt.Errorf("Request failed: %v", err)
}

API Documentation

This library is a drop-in replacement for the official OpenAI Go client that can be used with Tinfoil. All methods and types are identical. See the OpenAI Go client documentation for complete API usage and documentation.

Types

type Client

type Client struct {
	*openai.Client
	// contains filtered or unexported fields
}

Client wraps the OpenAI client to provide secure inference through Tinfoil

func NewClient

func NewClient(openaiOpts ...option.RequestOption) (*Client, error)

NewClient creates a new secure OpenAI client using default parameters

func NewClientWithParams

func NewClientWithParams(enclave, repo string, openaiOpts ...option.RequestOption) (*Client, error)

NewClientWithParams creates a new secure OpenAI client with explicit enclave and repo parameters

func (*Client) Enclave

func (c *Client) Enclave() string

func (*Client) HTTPClient

func (c *Client) HTTPClient() *http.Client

HTTPClient returns the underlying HTTP client that is configured with automatic certificate re-verification and is restricted to TLS connections to the verified enclave. This can be used for secure, direct HTTP requests to the enclave.

func (*Client) Repo

func (c *Client) Repo() string

func (*Client) Verify

func (c *Client) Verify() (*client.GroundTruth, error)

Verify re-verifies the enclave attestation and returns the ground truth
