From 50c71955283228984bb28459bd904c55d1b9f633 Mon Sep 17 00:00:00 2001 From: galz10 Date: Tue, 24 Feb 2026 13:17:43 -0800 Subject: [PATCH] feat(core): enhance FileSecretStorage with deep hardware binding and double encryption Implements elite security features for file-based secret storage fallback: - Deep Hardware Binding: Cryptographically ties secrets to Baseboard, Disk, and MAC serials. - Secret-Level Double-Encryption: Individually encrypts each secret within the vault. - Multi-Factor Sharding: Incorporates a hidden installation ID (~/.gemini_id) as a physical shard. - Atomic Operations: Prevents file corruption using temp-write and atomic rename. - Stealth Obfuscation: Uses binary-like naming and random padding to hide data length. - Graceful Degradation: Automatically handles headless environments without D-Bus. - Full backward compatibility with automatic upgrade from v1. - Removes noisy console.error in Keychain availability check. --- .../token-storage/file-secret-storage.test.ts | 195 ++++++++ .../mcp/token-storage/file-secret-storage.ts | 426 +++++++++++++++--- .../token-storage/keychain-token-storage.ts | 6 +- 3 files changed, 549 insertions(+), 78 deletions(-) create mode 100644 packages/core/src/mcp/token-storage/file-secret-storage.test.ts diff --git a/packages/core/src/mcp/token-storage/file-secret-storage.test.ts b/packages/core/src/mcp/token-storage/file-secret-storage.test.ts new file mode 100644 index 0000000000..4abf18b79c --- /dev/null +++ b/packages/core/src/mcp/token-storage/file-secret-storage.test.ts @@ -0,0 +1,195 @@ +/** + * @license + * Copyright 2025 Google LLC + * SPDX-License-Identifier: Apache-2.0 + */ + +import { describe, it, expect, beforeEach, afterEach, vi } from 'vitest';
