Yes. Exactly we followed the same and able to resolve errors. Thank you so much for the support and guidance. I'll get back if any further errors.
Thanks & Regards,

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.
