nomyo SDK -- Secure Inference Client

nomyo is a Python package that provides a secure, OpenAI-compatible interface for AI inference. It encrypts prompts and responses with AES-256-GCM before they leave your system and offers hardened processing options on the elevated tiers – inference inside an Intel SGX enclave and per-request TPM 2.0 hardware attestation. The binding description of what is encrypted, logged, and where plaintext exists is the Data Handling Commitments, Section 4.

Security Model

Hybrid Encryption

nomyo uses a dual-layer encryption approach:

1. AES-256-GCM – Encrypts the payload (prompts, messages, responses) with authenticated encryption
2. RSA-OAEP 4096-bit – Handles key exchange, providing secure key distribution

Forward Secrecy

Each request generates ephemeral AES keys that are destroyed after use. Even if a key is compromised, past and future communications remain secure.

Security Tiers

API Compatibility

nomyo is a drop-in replacement for the OpenAI Python SDK:

from nomyo import OpenAI

client = OpenAI(
    base_url="https://api.nomyo.ai/v1",
    api_key="your-nomyo-key"
)

response = client.chat.completions.create(
    model="nomyo.ai:teammate",
    messages=[{"role": "user", "content": "Hello"}]
)

Key Management

• Keys are generated and stored locally
• Support for hardware security modules (HSM)
• Automatic key rotation
• Secure key import/export

Migration from OpenAI

Migrating to nomyo requires minimal changes:

# Before (OpenAI)
from openai import OpenAI
client = OpenAI(api_key="your-openai-key")

# After (nomyo)
from nomyo import OpenAI
client = OpenAI(
    base_url="https://api.nomyo.ai/v1",
    api_key="your-nomyo-key"
)

All other code remains identical.

Installation

pip install nomyo

Data Privacy

What NOMYO stores, logs, encrypts, and whether your content is ever processed in plaintext is defined in the Data Handling Commitments. That document is the legally binding description, not this page.
