Release Notes

Releases follow semantic versioning.

Full details of the release notes can be viewed on GitHub.


The HibpClient class currently has a number of public methods:

  • GetAccountBreachesAsync(string emailAddress, HibpRequestOptions options = null)
  • GetBreachedSitesAsync(string domain = null)
  • GetBreachSiteByNameAsync(string breachName)
  • GetDataClassesAsync()
  • GetAccountPastesAsync(string emailAddress)

Note: Methods GetAccountBreachesAsync and GetAccountPastesAsync require a valid API key be provided.


var options = new HibpClientOptions
    ApiKey = "someApiKey",
    RetryOnRateLimitExceeded = true

IHibpClient client = new HibpClient(new HttpClient(), options);

var result = await client.GetAccountBreachesAsync("");

Console.WriteLine($"Number of breaches: {result.Count()}");


Account = Represented by an email address.

Breach = An instance of a system having been compromised by an attacker and the data disclosed.

Data Class = An attribute of a record compromised in a breach. For example, many breaches expose data classes such as "Email addresses" and "Passwords". A complete list of all data classes can be obtained by calling the GetDataClassesAsync method.

Pastes = Text pasted onto a website whereupon it receives its own unique URL so that it can then be shared with others who may want to view the paste.
