Powershell 部分匹配字符串密码复杂性

Question

I have two strings coming from a csv file:

$Password = "dkjhfd22dnrhfg"
$Username = "NewUser22d"

I'm trying to check for this: Not contain the user's account name or parts of the user's full name that exceed two consecutive characters.

If 3 or more characters are matched I would like to add it here:

if(($password -cmatch '[a-z]') -and ($password -cmatch '[A-Z]') -and ($password -match '\d') -and (($password).length -ge 18))

Questions:

1. How do I match?

2. How do I add to existing if statement.

Answer 1

Maybe it would be easier to run a function

Since you dont really need to look for (more then) the minimum password / username match

Function Check-Password{
    param(
        [string]$Username,
        [string]$Password,
        [int]$MatchLength
    )
    for($i = 0; $i -ne ($Username.Length - ($MatchLength - 1)); $i++){
        $Username.Substring($i, $MatchLength) | Where-Object {$Password -like "*$_*"}
    }
}

Check-Password -Username "NewUser22d" -Password "dkjhfd22dnrhfg" -MatchLength 3

This will return

22d
