Decrypt Google Chrome passwords

5

2

In this question How does Google Chrome store passwords? I found out how my Chrome passwords are encrypted. The passwords are encrypted with the current useraccount (of Windows).

I had saved my userdata from "C:\Users\%username%\AppData\Local\Google\Chrome\User Data" before reinstalling windows.

After putting the Data on the fresh installed system, I only have my chrome settings and bookmarks stored. There are no passwords in the list (in chrome)

With ChromePass I could only recover my website data and loginnames. (The password value is empty)

I know some of my passwords which are stored in the Login Data and the username and password on the old system.

Is it possible to decrypt my passwords ?

What exactly is the question? Did you backup all the required data in order to do this before you deleted the original data? – Ramhound – 2013-10-07T16:34:28.753

I did a backup of the UserData folder of Chrome which contains the file "Login Data" with the login data and encrypted passwords – waki – 2013-10-07T16:38:49.227

1So if you restore all the data in the current profile. You are saying that Chrome does not allow you to view the passwords? If thats the case then what you want isn't possible as the correct data wasn't backed up. – Ramhound – 2013-10-07T16:39:40.470

In the settings at saved passwords is shown nothing, but with the tool ChromePass, I get all Logindata expect the passwords (empty) – waki – 2013-10-07T16:41:37.487

did you originally password protect your passwords? – Ramhound – 2013-10-07T16:43:42.403

Have you tried ChromePasswordDecryptor? http://securityxploded.com/chromepassworddecryptor.php (softpedia says it's supported by ads) Never tried it. Use at your own risk.

I have tried it, but doesn't work, how in the linked thread, it is sayed, that the password is encrypted with the useraccount (of windows) – waki – 2013-10-07T17:06:13.870

@Ramhound: I didn't protect the passwords saved by chrome – waki – 2013-10-07T17:18:44.877

@waki - If you didn't protect your passwords there is nothing to decrypt because your passwords were never encrypted. – Ramhound – 2013-10-07T17:21:54.770

In the above mentioned thread is sayed, that the passwords are encrypted with the current useraccount. But I didn't do anything special to encrypt it – waki – 2013-10-07T17:26:23.390

Google Chrome on Windows encrypts your saved passwords using the Windows encryption function CryptProtectData. In order to decrypt the saved password not only do you have to be logged in with the same user password Chrome used to save it, but also be on the same computer.

From your description I understand you only reinstalled Windows, but are on the same computer. Try changing your password or create a new account with the same username and password you used before reinstalling to decrypt the passwords with ChromePass.

1I am on the same computer and I use the same username and password I have used before, but it doesn't work to decrypt with ChromePass. – waki – 2013-12-21T16:15:57.977
