PwnedPasswords.net

This is a very quick and dirty .net client for Troy Hunt's excellent PwnedPasswords service.

The library will call the PwnedPasswords service using a partial of a SHA1 hash of any password you give it. At no point does it send the password itself, or indeed anything except the first 5 characters of the SHA1 representation of that password.

This means you can safely check if a password is on a known password list without giving away the password itself.

How to use

Standard use:

// Create an instance of the client, then call CheckPassword:

var pwdClient = new PwnedPasswordsClient(); // Client instance, you can also pass in your own instance of HttpClient

if(pwdClient.CheckPassword("password")) // "password" can be any clear text password
{
    // If the method returns true, the password was known
    Console.WriteLine("pwned!");
}
else
{
    // If it returned false, the password is not currently known.
    Console.WriteLine("Not pwned!");
}

You can also check a SHA1 directly, if you don't feel comfortable passing a raw password around:

if(pwdClient.CheckSha1HashedPassword("21BD12DC183F740EE76F27B78EB39C8AD972A757"))
{
    Console.WriteLine("pwned!");
}
else
{
    Console.WriteLine("Not pwned!");
}
