Generate Random Password Powershell Function

I recently saw a tip from http://www.powershell.com that prompted me to make the below function. It generates random passwords with the length and number of special characters you specify. I hope someone else finds it useful.

If you are wondering how to include libraries in your code see below.

# Here is how your include
."C:\powershell\password_lib.ps1"

Here is the function to generate passwords

#Generate Random Password Function

# Based on Tip From PowerShell.com

function generate-password($length,$special){

# $length is the number of characters of the new password
# The default length is 8

# $special is the number of special characters the new password should contain
# The default number of special characters is 4

$Assembly = Add-Type -AssemblyName System.Web

if($length -ne $null -and $special -ne $null){

$password = [System.Web.Security.Membership]::GeneratePassword($length,$special)

}

if($length -ne $null -and $special -eq $null){

$password = [System.Web.Security.Membership]::GeneratePassword($length,4)

}

if($length -eq $null -and $special -ne $null){

$password = [System.Web.Security.Membership]::GeneratePassword(8,$special)

}

if($length -eq $null -and $special -eq $null){

$password = [System.Web.Security.Membership]::GeneratePassword(8,4)

}

return $password

}
