## Description

Boilerplate code templates for Tizen KeyManager integration. Generates C/C#/.NET code for password-protected secure data storage.

## When to Use

This is a Tizen security/IoT skill. Use when:
- Developing Tizen applications (web, native, .NET)
- Auditing Tizen app security
- Provisioning TizenRT/ARTIK IoT devices
- Implementing Tizen compliance
- Analyzing SMACK policies or Cynara access control

## Tizen Security Model

### SMACK (Simplified Mandatory Access Control Kernel)
- Linux kernel 3.12+ mandatory access control
- Process isolation via labels
- Prevent inter-app resource access

### Cynara
- Fast privilege access control service
- Policy-based permission checking
- External agent integration

### KeyManager
- Central secure storage repository
- Password-protected data access
- Certificate and key management

### Tizen Manifest
- Privilege declarations (public, partner, platform)
- App sandboxing configuration
- Resource access specifications

Overview

This skill provides boilerplate templates for integrating Tizen KeyManager into applications, generating C, C#, and .NET snippets for password-protected secure storage. It speeds up implementing secure key and certificate handling across Tizen native, web, and .NET projects. The templates follow Tizen security patterns and are suitable for IoT device provisioning and compliance checks.

How this skill works

The skill generates ready-to-use code that calls KeyManager APIs to store, retrieve, and protect secrets with password-based access controls. It includes manifest privilege hints, SMACK-aware recommendations, and Cynara permission patterns so generated code fits Tizen sandboxing and policy flows. Templates are modular so you can drop them into native C, C#, or .NET projects and adapt the configuration for device provisioning and certificate management.

When to use it

Building Tizen apps that need encrypted local storage or key management
Implementing certificate/key lifecycle in IoT devices (TizenRT/ARTIK)
Hardening app storage for audit or compliance with Tizen security guidelines
Prototyping secure credential storage for cross-platform .NET components
Reviewing or demonstrating secure storage patterns for SMACK/Cynara-aware apps

Best practices

Declare minimal required privileges in the Tizen manifest and test behavior with SMACK labels
Use strong passwords and recommend hardware-backed key storage when available
Rotate keys and provide clear migration paths in templates for key expiry or compromise
Wrap KeyManager calls with error handling and explicit permission checks for Cynara responses
Include unit tests that simulate denied permissions and manifest misconfigurations

Example use cases

Generate a C template to store device identity certificates with password protection for an ARTIK module
Create a .NET snippet that encrypts user credentials and integrates manifest privilege declarations
Provision a fleet of TizenRT devices using templates that standardize key import and certificate validation
Audit an app by swapping in the templates to verify manifest privileges, Cynara checks, and SMACK interactions
Demonstrate secure storage patterns in training materials or security reviews using ready-made examples

FAQ

Which languages and project types are supported?

Templates target native C, C#, and .NET Tizen projects and include manifest guidance for web and native app configurations.

Do templates handle SMACK and Cynara policy checks?

Yes. Templates include recommended manifest entries, sample Cynara permission checks, and SMACK-aware notes so the code behaves correctly in a sandboxed Tizen environment.
