Here is how you can create random passwords that meet certain requirements:
function Get-RandomPassword {
param(
$length = 10,
$characters =
param(
$length = 10,
$characters =
'abcdefghkmnprstuvwxyzABCDEFGHKLMNPRSTUVWXYZ123456789!"§$%&/()=?*+#_'
)
# select random characters
$random = 1..$length | ForEach-Object { Get-Random -Maximum $characters.length }
# output random pwd
$private:ofs=""
[String]$characters[$random]
)
# select random characters
$random = 1..$length | ForEach-Object { Get-Random -Maximum $characters.length }
# output random pwd
$private:ofs=""
[String]$characters[$random]
}
function Randomize-Text {
param(
$text
)
$anzahl = $text.length –1
$indizes = Get-Random -InputObject (0..$anzahl) -Count $anzahl
param(
$text
)
$anzahl = $text.length –1
$indizes = Get-Random -InputObject (0..$anzahl) -Count $anzahl
$private:ofs=''
[String]$text[$indizes]
}
function Get-ComplexPassword {
$password = Get-RandomPassword -length 6 -characters 'abcdefghiklmnprstuvwxyz'
$password += Get-RandomPassword -length 2 -characters '#*+)'
$password += Get-RandomPassword -length 2 -characters '123456789'
$password += Get-RandomPassword -length 4 -characters 'ABCDEFGHKLMNPRSTUVWXYZ'
$password = Get-RandomPassword -length 6 -characters 'abcdefghiklmnprstuvwxyz'
$password += Get-RandomPassword -length 2 -characters '#*+)'
$password += Get-RandomPassword -length 2 -characters '123456789'
$password += Get-RandomPassword -length 4 -characters 'ABCDEFGHKLMNPRSTUVWXYZ'
Randomize-Text $password
}
Get-ComplexPassword creates a 14-character password consisting of six lowercase characters, two special characters, two numbers, and four uppercase characters. This is done by creating four parts and then melting them together with Randomize-Text, which takes a text and randomly re-arranges the characters. With this toolset, you can then create almost any random password adhering to almost any complexity rule you are likely to run into.
