SecBuffer 和 SecBufferDesc 示例代码

此示例演示如何初始化安全缓冲区数组。 它显示了由连接的服务器端初始化的输入安全缓冲区，以准备调用 AcceptSecurityContext (General) 。 请注意，最后一个缓冲区包含客户端收到的不透明安全令牌，并且 SECBUFFER_READONLY 标志是在 SecBuffer 上设置的。

SecBuffer  Buffers[3];
SecBufferDesc BufferDesc;
BYTE *pHeader;
BYTE *pMessage;
BYTE *pTrailer;

//--------------------------------------------------------------------
// pHeader, pMessage, and pTrailer are BYTE strings.
// In a working program, they would be assigned string values.

BufferDesc.ulVersion = SECBUFFER_VERSION;
BufferDesc.cBuffers = 3;
BufferDesc.pBuffers = Buffers;

Buffers[0].cbBuffer = sizeof(pHeader);
Buffers[0].BufferType = SECBUFFER_READONLY | SECBUFFER_DATA;
Buffers[0].pvBuffer = pHeader;

Buffers[1].cbBuffer = sizeof(pMessage);
Buffers[1].BufferType = SECBUFFER_DATA;
Buffers[1].pvBuffer = pMessage;

Buffers[2].cbBuffer = sizeof(pTrailer);
Buffers[2].BufferType = SECBUFFER_READONLY | SECBUFFER_TOKEN;
Buffers[2].pvBuffer = pTrailer;
