198 NTLM message structure notes:
200 A 'short' is a 'network short', a little-endian 16-bit unsigned value.
202 A 'long' is a 'network long', a little-endian, 32-bit unsigned value.
204 A 'security buffer' represents a triplet used to point to a buffer,
205 consisting of two shorts and one long:
207 1. A 'short' containing the length of the buffer content in bytes.
208 2. A 'short' containing the allocated space for the buffer in bytes.
209 3. A 'long' containing the offset to the start of the buffer in bytes,
210 from the beginning of the NTLM message.
214 * Curl_sasl_decode_ntlm_type2_message()
216 * This is used to decode an already encoded NTLM type-2 message. The message
217 * is first decoded from a base64 string into a raw NTLM message and checked
218 * for validity before the appropriate data for creating a type-3 message is
219 * written to the given NTLM data structure.

224 * type2msg [in] - The base64 encoded type-2 message.
