AitherZero

2.0.0

src/public/Security/Sync-AitherSecretsToGitHub.ps1

#Requires -Version 7.0

<#
.SYNOPSIS
    Syncs local AitherZero secrets to GitHub repository secrets.

.DESCRIPTION
    Pushes locally stored credentials to GitHub Actions secrets.
    This enables a workflow where:
    1. Store secrets locally using Set-AitherCredential (encrypted, secure)
    2. Sync to GitHub for CI/CD use
    3. Load locally using Initialize-AitherSecrets for dev work
    
    GitHub Secrets are WRITE-ONLY by design - you cannot retrieve them.
    Your local vault is the source of truth.

.PARAMETER Names
    Specific secret names to sync. If not provided, syncs all API keys.

.PARAMETER Owner
    GitHub repository owner. Defaults to 'Aitherium'.

.PARAMETER Repo
    GitHub repository name. Defaults to 'AitherZero-Internal'.

.PARAMETER Force
    Skip confirmation prompts.

.EXAMPLE
    Sync-AitherSecretsToGitHub -Names "OPENAI_API_KEY", "ANTHROPIC_API_KEY"
    
    Syncs specific API keys to GitHub.

.EXAMPLE
    Sync-AitherSecretsToGitHub -Force
    
    Syncs all stored API keys to GitHub without prompting.

.NOTES
    Requires:
    - GitHub CLI (gh) authenticated: gh auth login
    - PyNaCl or libsodium for encryption (gh handles this automatically)
