RSA.HashData 方法

定義

計算二進位資料的雜湊值。Computes the hash value of binary data.

多載

HashData(Stream, HashAlgorithmName)

在衍生類別中覆寫時,會使用指定的雜湊演算法,來為指定的二進位資料流計算出雜湊值。When overridden in a derived class, computes the hash value of a specified binary stream by using a specified hashing algorithm.

HashData(Byte[], Int32, Int32, HashAlgorithmName)

在衍生類別中覆寫時,會使用指定的雜湊演算法,來為位元組陣列中的指定部分計算出雜湊值。When overridden in a derived class, computes the hash value of a specified portion of a byte array by using a specified hashing algorithm.
