In previous articles we have seen how to decrypt dpapi blobs.

What about chrome?
It uses user dpapi blobs to encrypt password in a sqlite db.
So following previous articles, nothing prevents one to decrypt a chrome db offline.

3 steps:
-retrieve the scrambled passwords along with the masterkey guid
-decrypt the masterkey
-retrieve the decrypted passwords with the decrypted masterkey

1/retrieve the scrambled passwords along with the masterkey guid

nthash-win64 /chrome /binary:C:\temp\login data /input:0000000000000000000000000000000000000000

2/decrypt the masterkey (identified by its guid in previous steps)
See previous article for more details about this steps.

NTHASH-win64.exe /decodemk /binary:C:\Users\erwan\AppData\Roaming\Microsoft\Protect\S-1-5-21-242

3/retrieve the decrypted passwords with the decrypted masterkey
