Public Shared Function Create () As KeyedHashAlgorithm

傳回

除非已經變更預設設定，否則為新的 HMACSHA1 執行個體。

屬性

ObsoleteAttribute

備註

根據預設，此多載會使用 HMACSHA1 索引鍵哈希演算法的實作。 如果您想要指定不同的實作，請使用 Create(String) 多載，讓您改為指定演算法名稱。 密碼編譯組態系統會定義 類別的預設實作 KeyedHashAlgorithm 。

由於 SHA1 的衝突問題，Microsoft 建議您使用以 SHA256 或更好的加密方式為基礎的安全性模型。
