Auth

ApiKey

Provides ApiKey authentication for ASP.NET Core applications.

Expects an ApiKey added to the HTTP header X-Api-Key with the secret key.

Dependency injection

//adds IOption<ApiKeyConfig> and set up authentication.
services.AddApiKeyAuthentication(configuration)

...

//Use the authentication middleware
application.UseApiKeyAuthentication();

Usage

Just use regular [Authorize] attribute on your controllers or actions.

Generation

//Generate a new ApiKey
ApiKeyGenerator.GenerateApiKey();
//uses System.Security.Cryptography.RandomNumberGenerator to generate a secure random key

//Generate a new ApiKey with specific length
int length = ...
ApiKeyGenerator.GenerateApiKey(length);

Time

Provides [ITimeProvider] as a scoped service.

Used to ensures that all requests within the same scope (e.g. HTTP request) get the same time.

Dependency injection

...
//Get scoped
services.AddScopedTimeProvider();

//Get fixed
DateTimeOffset someFixedTime = ...
services.AddFixedTimeProvider(someFixedTime);
...

Usage

...
class SomeClass(ITimeProvider timeProvider)
{
	void SomeMethod()
	{
		...
		var currentTime = timeProvider.UtcNow;
		...
	}
}
...
