v2.2.1 - TPM Documentation Update

Device Fingerprinting Pro v2.2.1

Release Date

December 21, 2025

Overview

This release updates PyPI documentation to include comprehensive TPM (Trusted Platform Module) dual-mode architecture documentation.

What's New

Documentation Updates

• Added TPM/Secure Hardware Fingerprinting section to PyPI README
• Documented dual-mode architecture (software and tpm_strict modes)
• Added platform-specific TPM support details
• Included code examples for both enforcement modes

TPM Dual-Mode Architecture (from v2.2.0)

Mode A: Software (Default)

• Optional TPM usage with graceful fallback
• Works on all platforms
• Recommended for general-purpose deployments

Mode B: TPM-Strict

• Mandatory TPM hardware attestation
• Explicit failure if TPM unavailable
• Recommended for high-security deployments

Platform Support

• Windows: TPM 2.0 via PowerShell/WMI
• macOS: Secure Enclave (T2 chip, Apple Silicon)
• Linux: TPM 2.0 via /sys/class/tpm

Installation

pip install device-fingerprinting-pro==2.2.1

Usage Examples

Software Mode (Default)

import device_fingerprinting as df

df.enable_tpm_fingerprinting(enabled=True)
fingerprint = df.generate_fingerprint(method="stable", mode="software")

TPM-Strict Mode

import device_fingerprinting as df

try:
    fingerprint = df.generate_fingerprint(method="stable", mode="tpm_strict")
except RuntimeError as e:
    print(f"TPM required: {e}")
