Creating a Hash Password via CMD line (Win 7)

Question

_{Monday, February 5, 2018 8:08 PM}

I am working on my company's computer image and I need to create a password hash for our answer file. I have scoured the internet to find this answer but, I cannot locate the proper command anywhere. I think there is the possibility of it not existing, or it doesn't not function the way I think it should. Any help would be great! Thank you.

The value should generally be created using the unattended setup tool.  However, I believe the string is stored as:

ConvertToBase64(<plaintext password>+AdministratorPassword)

For example, if your administrator password is Password1234, you would do this:

$Password = [System.Text.Encoding]::UTF8.GetBytes("Password1234AdministratorPassword")
$PasswordBase64 = [System.Convert]::ToBase64String($Password)

You could then see the result by typing:

$PasswordBase64

Which would show:

UGFzc3dvcmQxMjM0QWRtaW5pc3RyYXRvclBhc3N3b3Jk

To convert a value in a previously saved answer file:

$PasswordToConvert = "UGFzc3dvcmQxMjM0QWRtaW5pc3RyYXRvclBhc3N3b3Jk"
$PlainTextPassword = [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($PasswordToConvert)).TrimEnd("AdministratorPassword")

Under <autologon>, you can also flip <Plaintext> to true, and just use a plaintext password in the unattend answer file.
