feat: cookie-import-browser — Chromium cookie decryption module + tests
Pure logic module for reading and decrypting cookies from macOS Chromium browsers (Comet, Chrome, Arc, Brave, Edge). Supports v10 AES-128-CBC encryption with macOS Keychain access, PBKDF2 key derivation, and per-browser key caching. 18 unit tests with encrypted cookie fixtures.

/**
|
||||
* Chromium browser cookie import — read and decrypt cookies from real browsers
|
||||
*
|
||||
* Supports macOS Chromium-based browsers: Comet, Chrome, Arc, Brave, Edge.
|
||||
* Pure logic module — no Playwright dependency, no HTTP concerns.
|
||||
*
|
||||
* Decryption pipeline (Chromium macOS "v10" format):
|
||||
*
|
||||
* ┌──────────────────────────────────────────────────────────────────┐
|
||||
* │ 1. Keychain: `security find-generic-password -s "<svc>" -w` │
|
||||
* │ → base64 password string │
|
||||
* │ │
|
||||
* │ 2. Key derivation: │
|
||||
* │ PBKDF2(password, salt="saltysalt", iter=1003, len=16, sha1) │
|
||||
* │ → 16-byte AES key │
|
||||
* │ │
|
||||
* │ 3. For each cookie with encrypted_value starting with "v10": │
|
||||
* │ - Ciphertext = encrypted_value[3:] │
|
||||
* │ - IV = 16 bytes of 0x20 (space character) │
|
||||
* │ - Plaintext = AES-128-CBC-decrypt(key, iv, ciphertext) │
|
||||
* │ - Remove PKCS7 padding │
|
||||
* │ - Skip first 32 bytes (HMAC-SHA256 authentication tag) │
|
||||
* │ - Remaining bytes = cookie value (UTF-8) │
|
||||
* │ │
|
||||
* │ 4. If encrypted_value is empty but `value` field is set, │
|
||||
* │ use value directly (unencrypted cookie) │
|
||||
* │ │
|
||||
* │ 5. Chromium epoch: microseconds since 1601-01-01 │
|
||||
* │ Unix seconds = (epoch - 11644473600000000) / 1000000 │
|
||||
* │ │
|
||||
* │ 6. sameSite: 0→"None", 1→"Lax", 2→"Strict", else→"Lax" │
|
||||
* └──────────────────────────────────────────────────────────────────┘
