static HMAC^ Create()

Return Value

Type: System.Security.Cryptography::HMAC
A new SHA-1 instance, unless the default settings have been changed by using the <cryptoClass> element.

By default, this overload uses the SHA-1 implementation of HMAC. If you want to specify a different implementation, use the Create(String) overload, which lets you specify an algorithm name, instead.
