Source:: DSA.cs

尝试将指定数据的 DSA 签名创建到所提供的缓冲区中。

public:
 virtual bool TrySignData(ReadOnlySpan<System::Byte> data, Span<System::Byte> destination, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, [Runtime::InteropServices::Out] int % bytesWritten);

public virtual bool TrySignData (ReadOnlySpan<byte> data, Span<byte> destination, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, out int bytesWritten);

abstract member TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * int -> bool
override this.TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * int -> bool

Public Overridable Function TrySignData (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, ByRef bytesWritten As Integer) As Boolean

参数

data: ReadOnlySpan<Byte>

要进行哈希处理和签名的数据。

destination: Span<Byte>

接收签名的字节范围。

hashAlgorithm: HashAlgorithmName

要使用的哈希算法的名称。

bytesWritten: Int32

此方法返回时，包含一个指示写入 destination 的字节数的值。

Boolean

如果 destination 足够大可以接收结果，则为 true；否则为 false。
