      encryptionKey: Base64Url.Decode("sIxwz7yw62yrfoLGt12lIHKuYrK_S5kLuApI2BQe7Ac=")
    , integrityKey : Base64Url.Decode("v3fsVcMBMMHYzRhi7SpM0sdqwzvAxM6KPTu9OtVod5I=")
));

var cipherPrice = "OG46wAAMCggBI0VniavN7-mNy0VTKPbB3o5CMQ==";
var success = crypto.TryDecryptPrice(cipherPrice, out var price);

Console.WriteLine(success);  // true
