Portability on Windows #591

crazy-max · 2018-11-18T00:49:40Z

Closes #444

About

The purpose of this PR is to allow the portability of Chromium on Windows with the addition of two new switches :

disable-machine-id : Allows disabling the machine ID generation on Windows.
disable-encryption : Allows disabling encryption of cookies, passwords, settings. Should be ONLY used if your hard drive is encrypted or if you know what you are doing 🙃

This allows the portability of everything, except certificates.

Related threads :

Test

disable-machine-id

Launch chormium with switch --disable-machine-id
Install an extension
Close chormium and copy data to a second computer
Launch chormium on the second computer
The extension must be ok

disable-encryption

Launch chormium with switch --disable-encryption
Login to a known website with credentials and save them (will add unencrypted cookies and passwords to database)
Close chormium and copy data to a second computer
Launch chormium on the second computer
You must be still logged in on the website and credentials must be kept intact in the database

use both switches

Previous and following settings must be ok too :
- Default search engine
- Homepage
- Startup pages
- Pinned tabs

Looking good, but a couple questions:

Why is this marked as a WIP? What else needs to be done?
What happens if you disable machine ID but leave encryption enabled? Is encryption still tied to the current machine? Are the machine ID and encryption mechanisms independent of each other?

@Eloston

WIP to handle certificates but I think we cannot do something about it so feel free to remove the WIP :)
For me encryption is not tied to machine-id. Machine ID seems to be linked to extensions and only used on Windows.

BTW on Windows, does Chromium store credentials internally in the user data directory by default? Or is there a credential storage mechanism that Chromium uses? I'm trying to understand why passwords are included in the encryption.

crazy-max · 2018-11-19T22:27:54Z

@Eloston Passwords are stored in the user data directory in a sqlite database called Login Data with the following schema :

BEGIN TRANSACTION;
CREATE TABLE stats (origin_domain VARCHAR NOT NULL, username_value VARCHAR, dismissal_count INTEGER, update_time INTEGER NOT NULL, UNIQUE(origin_domain, username_value));
CREATE TABLE meta(key LONGVARCHAR NOT NULL UNIQUE PRIMARY KEY, value LONGVARCHAR);
CREATE TABLE logins (origin_url VARCHAR NOT NULL, action_url VARCHAR, username_element VARCHAR, username_value VARCHAR, password_element VARCHAR, password_value BLOB, submit_element VARCHAR, signon_realm VARCHAR NOT NULL, preferred INTEGER NOT NULL, date_created INTEGER NOT NULL, blacklisted_by_user INTEGER NOT NULL, scheme INTEGER NOT NULL, password_type INTEGER, times_used INTEGER, form_data BLOB, date_synced INTEGER, display_name VARCHAR, icon_url VARCHAR, federation_url VARCHAR, skip_zero_click INTEGER, generation_upload_status INTEGER, possible_username_pairs BLOB, UNIQUE (origin_url, username_element, username_value, password_element, signon_realm));
CREATE INDEX stats_origin ON stats(origin_domain);
CREATE INDEX logins_signon ON logins (signon_realm);
COMMIT;

crazy-max · 2018-11-19T22:30:26Z

And Chromium uses CryptProtectData to encrypt passwords in the password_value BLOB.

Eloston · 2018-11-19T22:51:25Z

I see, it kinda sucks that the Windows version doesn't use a credentials storage. Thanks for the info.

Eloston

Thanks 👍

@Eloston
Thanks!
Good job, much desired behaviour.

xixiranran · 2019-03-25T07:52:55Z

请问这两个参数现在还支持最新的chrome吗？

GeographicCone · 2019-08-31T03:03:44Z

Thank you for this patch. Works great with 76.0.3809.100.

crazy-max · 2020-03-22T02:06:56Z

Hi @Eloston,

Looks like the patches for portability on Windows have been removed?

Eloston · 2020-03-23T00:29:57Z

@crazy-max This was merged before the fragmentation refactor (i.e. before platform repos were created). They now live in here: https://github.com/ungoogled-software/ungoogled-chromium-windows/tree/master/patches/ungoogled-chromium/windows

crazy-max · 2020-03-23T08:15:20Z

@Eloston Perfect thanks

gilluc · 2020-10-30T22:16:57Z

Why appdata/local/chromium is not stored just beside chromium.exe to be really portable??
This could make it possible for me to use ungoogled chromium on my two pcs from my Nextcloud drive...
I would have the same extensions and bookmarks.

mikhoul · 2021-10-06T18:12:30Z

@Eloston @crazy-max I have a question I want to transfer my "user data" profile (from my Windows desktop) to my Windows laptop without having to reinstall all my extensions and configure their settings.

There is also unpacked customized extensions in dev mode that I want to transfer too (they are inside a specific sub-folder inside the "user data" folder. Of course I want to keep all the custom settings and flags related to the browser.

My question is: **How I can transfer all my extensions (packed/unpacked with their settings) + the browser/flags settings with the disable-machine-id/disable-encryption switch ??? 🤔

I'm not sure of the right procedure since my extensions were installed without the "disable-machine-id" switch

Regards

iGom · 2022-07-05T18:10:14Z

Do we also lose history, settings, extensions and bookmarks even when we update/upgrade ungoogled-chromium on the same machine on Windows??? Because that's what happened to me right now.

MarvinFS · 2024-03-06T05:53:08Z

I have been using command line switches disable-machine-id and disable-encryption for ages now, all was good, but I noticed on the main project website these 2 parameters are now crossed out, but I can't find any details what happened. Also with the latest build I noticed all my cookies doesn't survive browsers restart and I'm forced to login to absolutely all sites from scratch each time, which is a huge issue for me. I initially thought that is related to 3PCD, but doesn't seems like, as I manually marked all my required websites as allowed for 3rd party cookies still if I restart the browser I'm forced to login again everywhere absolutely. I was never the case and something changed only in the latest build 122.xxx, but I'm unable to find what it was exactly. Any suggestions are appreciated; possible to DM if needed.

mavorse · 2024-04-10T15:42:12Z

Do these switches still work with the current version of Chromium? I tried using them on Vivaldi, and they didn't seem to function.

ltguillaume · 2024-04-11T11:32:04Z

@mavorse Apparently it's --disable-encryption-win now, see macchrome/winchrome#135

tomasz1986 · 2024-04-11T14:04:38Z

@mavorse Apparently it's --disable-encryption-win now, see macchrome/winchrome#135

According to https://github.com/ungoogled-software/ungoogled-chromium-windows/blob/master/patches/ungoogled-chromium/windows/windows-disable-encryption.patch, the switch should still be just --disable-encryption. Please keep in mind that the binaries from https://github.com/macchrome/winchrome are not official and may have additional modifications in comparison to the official Windows binaries distributed by https://github.com/ungoogled-software.

ltguillaume · 2024-04-11T16:40:24Z

This isn't a change by macchrome, I know that for sure (see the issue I linked). That being said, I myself didn't have any success using --disable-encryption-win, but some others reported they did.

Nifury · 2024-04-11T20:13:40Z

Well, passing --disable-encryption-win to chromium is the same as passing nothing. It's just an invalid argument.
disable-encryption-win doesn't even exist in either UG or winchrome.

ltguillaume · 2024-04-11T20:17:16Z

Ha! I knew it! Thanks for checking this and sorry for paying forward false information. I'll report back to those who think it worked.

ltguillaume · 2024-04-24T10:22:38Z

I just saw this patch related to the issue: Alex313031/thorium@1ac0e00

AJolly · 2024-05-10T02:04:47Z

Fyi if you reaaally want its possible to export dpapi keys and also resign chrome/chromiums securepreferences.

AJolly · 2024-07-20T01:31:19Z

Also the issue with the current patches is if you ever accidentally run the exe without having those cli flags set, it'll wipe out the existing settings. ie #668

PF4Public · 2024-07-20T09:14:45Z

@AJolly Please file proper issues into Windows repository if you think those issues are a significant ones.

Add disable-machine-id and disable-encryption switches
