The GetPasswordStrength() method allows you to evaluate a password's strength using Passliss' standards. It returns a PasswordStrength enum.

It's in:

LeoCorpLibrary.Password.GetPasswordStrength() {...}

It has one argument:

Type Argument Description Example
string password The password to test "Ftel_UGbn542"

Here's an example of usage:

C#

string[] passwords =
{
	"Ifhi2ztbg1",

	"Lo8_n0D",
	"uifVyuiVVH_çVIvc",
	"gygYUI4"
};
		
List<PasswordStrength> forces = new List<PasswordStrength>();
		
for (int i = 0; i < passwords.Length; i++)
{
	forces.Add(Password.GetPasswordStrength(passwords[i]));
}

/* 
forces' content:
Medium
Low
Good
VeryGood
Medium
*/

VB

Dim passwords As String() = {"Ifhi2ztbg1", "pars132", "Lo8_n0D", "uifVyuiVVH_çVIvc", "gygYUI4"}

Dim forces As List(Of PasswordStrength) = New List(Of PasswordStrength)()

For i As Integer = 0 To passwords.Length - 1
    forces.Add(Password.GetPasswordStrength(passwords(i)))
Next
' forces' content:
' Medium
' Low
' Good
' VeryGood
