Usage Instructions

Returns all accounts that have been pwned via the supplied email address / username.

Get-PwnedAccount -csv c:\temp\emailaddress.csv -apiKey "xxxxxxxxxxxxxxx"
Imports a list of email addresses in csv format. Each email address being a seperate row.

Get-PwnedPassword -Password monkey
Identifies if the password has been found. *No API key required

Get-PwnedPassword -Password monkey -Padding false
Identifies if the password has been found with response padding removed. *No API key required

$Password = Read-host -AsSecureString
Get-PwnedPassword -SecureString $Password Identifies if the password, in the SecureString variable $Password, has been found

Get-PwnedPassword -SHA1 AB87D24BDC7452E55738DEB5F868E1F16DEA5ACE
Identifies if the SHA1 hash of the password has been found. *No API key required

Further examples for each function can be found by typing
Get-Help {function name} -Examples

Future

Testing with an API Key!

Issues

The HIBP API now requires the use of a UserAgent. Old versions didn't specify this by default. Always make sure you're running the latest version.

If using the CSV import functionality of Get-PwnedAccount. The default 1500 millisecond delay between checking pwned accounts may not be large enough and cause rate-limiting. Increasing the rate limit can be achieved with parameter "RateLimit" and increasing the value above 1500.
