While they are both versions of the Stanford Javascript Crypto Library (SJCL) and share about 99% of the same logic, Code 2 contains environment-safety modifications that are missing in Code 1.
Specifically, Code 2 has been updated to be more "environment-aware" (likely to prevent crashes in Node.js or Server-Side Rendering environments), whereas Code 1 is a more traditional browser-only minification.
Key Logical Differences
Here are the specific areas where the logic differs beyond simple formatting:
1. Environment Safety Checks (window and document)
In the sjcl.random.startCollectors and stopCollectors functions, Code 2 adds checks to see if window or document are defined before accessing them.
Code 1:
Javascript
if(window.addEventListener){ ... }
else if(document.attachEvent){ ... }
Logic: This will throw a ReferenceError in environments like Node.js because window is not defined.
Code 2:
Javascript
if (typeof window !== "undefined" && window.addEventListener) { ... }
else if (typeof document !== "undefined" && document.attachEvent) { ... }
Logic: This is safe. It checks the type first, so it won't crash in non-browser environments.
2. Error Handling Removal
In the startCollectors function, Code 1 has a fallback error that Code 2 has removed.
Code 1:
Javascript
else throw new sjcl.exception.bug("can't attach event");
Code 2: The else block is entirely removed. If it can't find window or document, it simply does nothing rather than throwing an exception.
3. Stop Collectors Logic
A similar change exists in stopCollectors:
Code 1: Directly checks window.removeEventListener.
Code 2: Checks typeof window !== "undefined" before attempting to access window.removeEventListener.
While they share the same core cryptographic libraries (SJCL) and general business logic, Code 2 is a significantly modified version of Code 1, specifically updated to be compatible with Chrome Extension Manifest V3 (MV3). Code 1 is written for the older Manifest V2 (MV2) standard.
Here are the specific logical and functional differences:
1. Global Scope Reference (window vs. self)
Since Manifest V3 uses Service Workers (which do not have access to the window object), the global scope references have been changed.
Code 1: Uses window (e.g., n='undefined'!=typeof window&&window===this?this... and window.OnePassword=r).
Code 2: Uses self or globalThis (e.g., n = 'undefined' != typeof self && self.self === self ? self... and self.OnePassword= r).
2. Browser Action API
Chrome changed the "Browser Action" API to a generic "Action" API in Manifest V3.
Code 1: Uses chrome.browserAction (e.g., chrome.browserAction.onClicked... and chrome.browserAction.enable()).
Code 2: Uses chrome.action (e.g., chrome.action.onClicked... and chrome.action.enable()).
3. Navigation Interception (webRequest vs. tabs)
This is the most significant logical rewrite. Manifest V3 restricts the use of blocking webRequest.
Code 1: Uses chrome.webRequest.onBeforeRequest with the ['blocking'] attribute to intercept URLs containing onepasswdfill.
Code 2: Completely removes the webRequest logic and replaces it with a chrome.tabs.onUpdated listener. It now watches for tab updates to detect those specific URLs instead of intercepting the network request.
4. Context Menus Implementation
Code 1: Uses the onclick property directly inside the chrome.contextMenus.create object.
Code 2: Removes the onclick property from the creation object (as it's forbidden in MV3) and implements a centralized listener using chrome.contextMenus.onClicked.addListener. It also adds a mandatory id to the menu item.
5. URL API Modernization
Code 1: Accesses the URL constructor via window.URL || window.webkitURL.
Code 2: Accesses it via globalThis.URL || URL.
