Can't decrypt password in Chrome v135.0.7049.96

[altintop382]

After I updated my chrome, this script can't decrypt the passwords saved in my chrome profile.
I think Chrome updated their hashing algorithm.

I replicated your issue. I confirm, it can't decrypt Chrome passwords.

Also unable to decrypt cookie value

Yes, Chrome updated their security mechanism. They use app_bound_encryption_key to encrypt password and cookie.
Problem is that we need Administrator Privilege to decrypt this key.

[Admin9961]

It's not just administrator privileges, entire code needs refactoring. I already tried to run it as administrator, but it didn't work.

Hi @altintop382 — the main branch now ships full Chrome v20 (App-Bound Encryption) support, which covers the decryption changes Google rolled out in recent Chrome versions. Details and build instructions are here:

Please rebuild from main and try again on your current Chrome version. Closing as completed — feel free to reopen (or open a fresh issue) if the problem still reproduces after building from main.
