Dear all,

Kindly help me out in knowing how to disable TLS1.0 and TLS1.1 while compiling openssl package.
I am using 1.0.2n openssl version and disabled SSLv1 and v2 using -DSSL_OP_NO_SSLv2, -DOPENSSL_NO_SSL3 and -DOPENSSL_NO_SSL2.

I also have a doubt on difference between -DSSL_OP_NO_SSLv2, -DOPENSSL_NO_SSL3 and -DOPENSSL_NO_SSL2.
Can someone please explain the difference.

Thanks in advance,
Chethan Kumar
