Create the Composite Key. The process starts by creating a master key from all of the keys provided by the user (generally a password, key-file and/or Windows User Account). This is achieved by appending the bytes of the SHA256 hash for each of the keys into a single composite, which is then hashed with with SHA256. The 'composite key is invalid' message indicates the user has supplied the wrong Master Key. It is not an indication that the password database is corrupt.

(Note i believe a PoshKeePass module has been created by Jason Fossen over on GitHub – I recommend to use that going forward)

When you take over a large estate where the same username and password has been used for the local admin – the first thing that comes to mind was how can I automate this?

We were still in the process of trialing LastPass for Enterprise and therefore was still using KeePass. I come across a great script which I slightly tweaked which allows you to:

• Define local user account
• Add account to local admins group
• Generate random 20 character password
• Sets password to never expire (depending on compliance of course)
• Saves information into KeePass
