Now lets see few examples about Get-PasswordNumber.

Examples

Example 1

In this example we will get the number of possible passwords that are two to five characters based on the character set “a,b,c,1,2,3,$,*,&”.

PS C:\> Get-PasswordNumber -CharacterSet "a,b,c,1,2,3,$,*,&" -MinCharacters 2 -MaxCharacters 5
66420

Example 2

We will use the same characters as example 1 but we would like also to include the capital letters of “a,b,c”.

PS C:\> Get-PasswordNumber -Characters "a,b,c,1,2,3,$,*,&" -MinCharacters 2 -MaxCharacters 5 -IncludeCapital
271440

Example 3

For this example we need only the capital letters of “a,b,c” using the same character set of example 1.

PS C:\> Get-PasswordNumber -Characters "a,b,c,1,2,3,$,*,&" -MinCharacters 2 -MaxCharacters 5 -CapitalOnly
66420

Example 4

If we want to use the whole alphabet without any numbers and symbols, then we can use the word alphabet for our characters set.

PS C:\> Get-PasswordNumber -Characters alphabet -MinCharacters 2 -MaxCharacters 5
12356604

Example 5

We are able also to keep a specific pattern in our generated passwords, by defining more than one characters between commas.

Get-PasswordNumber "av,b,c" -MinCharacters 2 -MaxCharacters 2
9

Example 6

Get-Password can accept String values from the pipeline.

PS C:\> "a,b,c" | Get-PasswordNumber -MinCharacters 2 -MaxCharacters 2
9

Example 7

You can also use the output of the cmdlet into other commands.

PS C:\> Get-PasswordNumber -CharacterSet "ad,b,c" -MinCharacters 2 -MaxCharacters 2 | ForEach-Object {$_ * 2}
18
