Hi everyone,

I apologize for Comic Sans. And honestly I didn't know using it implies
this many impressions. As I said my other subscription named "Ananthaneni
Saiteja Chowdary" is my outlook account that i use for my office
work(because I am using a QHD resolution my fonts are so small so i
selected the font that looks good for me to read.)  I actually posted two
questions one from this email and other from outlook account. This question
was actually posted through my outlook account in the beginning, and just
as a followup and to include some more information in my question I thought
of asking the question again. So I copied the contents of my previous mail
and added few more info at the end in my Mail app, unfortunately the font
got changed to comic sans. Its not that i knowingly changed the font to
impress or insult. I am a non native English speaker and I sometimes don't
understand the exact emotion or feeling in non-technical conversation.

I am using OpenSSL client to create a custom TLS client which can send or
manipulate the default TLS handshake messages so that i can test for any
bugs in our TLS server implementation. I spent about 4 months in reading
OpenSSL code and making changes and adding new arguments to modify the
default client. So in that process i came across the WPACKET API. For
framing SSL records I had to use it.

I will post the question again in a new thread. Please take a look at it
and help me out.
