Encodes the "blob" (also known as "temp" in the official documentation).

This value is used in calculating/generating both the NT response and the
base session key.

@param DateTime $time The current time.
@param string $client_challenge A randomly generated 64-bit (8-byte)
unsigned client-generated binary string.
@param string $target_info The "TargetInfo" data sent by the server and
encoded in the server challenge.
@return string The encoded blob as a binary string.
Encodes the blob ( also known as temp in the official documentation ) .
