I wonder if others noticed too. I have a powershell script connecting via new-pssession to some other machines (windows servers) and the credentials are saved as XML via
$credential = Get-Credential
$credential| export-clixml somepath.xml
After september updates it can no longer import those XML files because
Import-CliXml : Key not valid for use in specified state.
If I recreate them again with the same credential set it works again! But I see the string in there is different! Seems like some crypto have changed and I will have to recreate all those saved credentials :-\
Is it possible patch caused this or am I doing something else wrong?
As mentioned in comments, the encryption is based on current windows user (including password).
To import the xml after changing windows password, you'll have to export it again first.
There's a new vault module from MS to serve a similar purpose, but it's still a work-in-progress at the moment. Maybe more relevant to future readers.
