Not sure if we need to use getMasterKey API for that. You can use SSL_SESSION_get_master_key() for this. Note this comment in the RETURN VALUES section: "For the other functions, if outlen is greater than 0 then these functions return the number of bytes actually copied, which will be less than or equal to outlen. If outlen is 0 then these functions return the maximum number of bytes they would copy -- that is, the length of the underlying field." So to discover the master_key_length call the function with outlen to zero. You can then allocate an appropriate sized buffer and call the function again in order to get the actual master key.
