Tinfoil CLI

A command-line interface for making verified HTTP requests to Tinfoil enclaves and validating attestation documents.

Installation

Pre-built binaries

Download the latest release for your OS from the Releases page.

Install Script

You can also install tinfoil CLI using our install script. This script automatically detects your operating system and architecture, downloads the correct binary, and installs it to /usr/local/bin.

Run the following command:

curl -fsSL https://github.com/tinfoilsh/tinfoil-cli/raw/main/install.sh | sh

Note: If you receive permission errors (for example, if you’re not running as root), you may need to run the command with sudo:

sudo curl -fsSL https://github.com/tinfoilsh/tinfoil-cli/raw/main/install.sh | sh

Build from source

1. Ensure you have Go installed.
2. Clone the repository:

git clone https://github.com/tinfoilsh/tinfoil-cli.git
cd tinfoil-cli

3. Build the binary:

go build -o tinfoil

Use "tinfoil [command] --help" for more information about a command.

Chat

The chat command lets you interact with a model by simply specifying a model name and your prompt. You need to specify the model with the -m flag.

Using the Chat Command

Basic Usage (running DeepSeek R1)

tinfoil chat -m deepseek-r1-70b -k "YOUR_API_KEY" "Why is tinfoil now called aluminum foil?"

This command loads the enclave host and repo values for the specified model from config.json.

Specifying a Custom Model

For custom models not included in config.json, supply the model name along with the -e and -r overrides:

tinfoil chat -m custom-model -k "YOUR_API_KEY" "Explain string theory" \
  -e custom.enclave.example.com \
  -r cool-user/custom-model-repo

If you omit -e or -r for a model that isn't in the configuration, a warning will be displayed prompting you to specify these flags.

Command Options

• -m, --model: The model name to use for chat. Must be specified.
• -k, --api-key: The API key for authentication.
• -e, --host: The hostname of the enclave. Optional if defined in the config file.
• -r, --repo: The GitHub repository containing code measurements. Optional if defined in the config file.

Embed

The embed command allows you to generate embeddings for text inputs. By default, it uses the nomic-embed-text model.

Using the Embed Command

With Default Model

tinfoil embed "This is a text I want to get embeddings for."

This command uses the default model nomic-embed-text and loads the enclave host and repo values from config.json.

With Multiple Text Inputs

You can provide multiple text inputs to get embeddings for all of them:

tinfoil embed "First text" "Second text" "Third text"

Specifying a Custom Model

tinfoil embed -m custom-embed-model -k "YOUR_API_KEY" "Text to embed" \
  -e custom.enclave.example.com \
  -r cool-user/custom-model-repo

Command Options

• -m, --model: The model name to use for embeddings. Defaults to nomic-embed-text.
• -e, --host: The hostname of the enclave. Optional if defined in the config file.
• -r, --repo: The GitHub repository containing code measurements. Optional if defined in the config file.

Attestation

Verify Attestation

Use the attestation verify command to manually verify that an enclave is running the expected code. The output will be a series of INFO logs describing each verification step.

Sample successful output:

$ tinfoil attestation verify \
  -e llama3-3-70b.model.tinfoil.sh \
  -r tinfoilsh/confidential-llama3-3-70b

INFO[0001] Measurements match  

Audit Attestation

You can also verify attestations at random and record a machine-readable audit log. Use the attestation audit command for this purpose.

By default the audit record is printed to stdout as JSON. To write it to a file, use the -l/--log-file flag:

tinfoil attestation audit \
  -e llama3-3-70b.model.tinfoil.sh \
  -r tinfoilsh/confidential-llama3-3-70b \
  -l /var/log/tinfoil_audit.log

The audit log record includes the timestamp, enclave host, code and enclave measurement fingerprints, and the verification status.

Proxy

Use tinfoil proxy to start a local HTTP proxy that verifies connections and forwards them to the specified enclave.

tinfoil proxy \
  -r tinfoilsh/confidential-llama3-3-70b-64k \
  -e llama3-3-70b-64k.model.tinfoil.sh \
  -p 8080

Docker

A docker image is available at ghcr.io/tinfoilsh/tinfoil-cli.

Troubleshooting

Common error resolutions:

• PCR register mismatch: Running enclave code differs from source repo
