示例

下面的示例计算SHA512Managed的data哈希，并将结果存储在result中。 此示例假定有一个预定义的常量 DATA_SIZE。

byte[] data = new byte[DATA_SIZE];
byte[] result;

using (SHA512 shaM = new SHA512Managed())
{
    result = shaM.ComputeHash(data);
}

Dim data(DATA_SIZE) As Byte
Dim result() As Byte

Using shaM As New SHA512Managed()
    result = shaM.ComputeHash(data)
End Using

注解

哈希用作表示大量数据的固定大小的唯一值。 如果相应的数据也匹配，则两组数据集的哈希应匹配。 对数据的小更改会导致哈希中出现大量不可预知的更改。

算法的 SHA512Managed 哈希大小为 512 位。
