Declare class:

class User
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Configure Func:

var sha256 = FingerprintBuilder<User>
    .Create(SHA256.Create())
    .For(p => p.FirstName)
    .For(p => p.LastName)
    .Build();

Get hash:

var user = new User { FirstName = "John", LastName = "Smith" };
var hash = sha256(user).ToLowerHexString(); // 62565a67bf16004038c502eb68907411fcf7871c66ee01a1aa274cc18d9fb541
