<br>
You can use SSL_SESSION_get_master_key() for this.<br>
<br>
Note this comment in the RETURN VALUES section:<br>
<br>
"For the other functions, if outlen is greater than 0 then these<br>
functions return the number of bytes actually copied, which will be less<br>
than or equal to outlen. If outlen is 0 then these functions return the<br>
maximum number of bytes they would copy -- that is, the length of the<br>
underlying field."<br>
<br>
So to discover the master_key_length call the function with outlen to<br>
zero. You can then allocate an appropriate sized buffer and call the<br>
function again in order to get the actual master key.<br>
<br>
