puts "🎉 Encrypted OIDC Authentication Implementation Test Complete!"
puts "\n📋 Implementation Summary:"
puts "   ✅ Encrypted JWT storage using Rails 7+ built-in encryption"
puts "   ✅ PKCE support maintained from existing implementation"
puts "   ✅ Automatic token refresh middleware"
puts "   ✅ JWT signature verification (optional, configurable)"
puts "   ✅ Secure cookie handling (HttpOnly, Secure, SameSite)"
puts "   ✅ Backward compatibility with existing sessions"
puts "   ✅ Enhanced logout functionality"
puts "\n🔧 To enable in production:"
puts "   1. Configure OIDC environment variables"
puts "   2. Optional: Set OIDC_VERIFY_JWT_SIGNATURE=true for extra security"
puts "   3. Run bundle install to install the new jwt gem"
