Encrypts or sign the data.<p>
This is a more complicated version of <a class="el" href="group__gssapi.html#g89a6d98056b75a8a25152de268833f51">gss_wrap()</a>, it allows the caller to use AEAD data (signed header/trailer) and allow greater controll over where the encrypted data is placed.<p>
The maximum packet size is gss_context_stream_sizes.max_msg_size.<p>
The caller needs provide the folloing buffers when using in conf_req_flag=1 mode:<p>
<ul>
<li>HEADER (of size gss_context_stream_sizes.header) { DATA or SIGN_ONLY } (optional, zero or more) PADDING (of size gss_context_stream_sizes.blocksize, if zero padding is zero, can be omitted) TRAILER (of size gss_context_stream_sizes.trailer)</li></ul>
<p>
<ul>
<li>on DCE-RPC mode, the caller can skip PADDING and TRAILER if the DATA elements is padded to a block bountry and header is of at least size gss_context_stream_sizes.header + gss_context_stream_sizes.trailer.</li></ul>
<p>
HEADER, PADDING, TRAILER will be shrunken to the size required to transmit any of them too large.<p>
To generate <a class="el" href="group__gssapi.html#g89a6d98056b75a8a25152de268833f51">gss_wrap()</a> compatible packets, use: HEADER | DATA | PADDING | TRAILER<p>
When used in conf_req_flag=0,<p>
<ul>
<li>HEADER (of size gss_context_stream_sizes.header) { DATA or SIGN_ONLY } (optional, zero or more) PADDING (of size gss_context_stream_sizes.blocksize, if zero padding is zero, can be omitted) TRAILER (of size gss_context_stream_sizes.trailer)</li></ul>
<p>
The input sizes of HEADER, PADDING and TRAILER can be fetched using <a class="el" href="group__gssapi.html#g6216cfcb1ba8dc2d1a1d680d21752f26">gss_wrap_iov_length()</a> or gss_context_query_attributes().
