I don't know if its just my email client, but the code sample that you sent through is completely unintelligible - there are no line breaks. However, from what I could work out, your server seems to be using OpenSSL to listen for incoming SSL/TLS connections. So I think you are asking the wrong question (on the wrong list!). OpenSSL's implementation of SSL/TLS is standards based. You should be able to use any SSL/TLS compliant library in order to be able to establish communication with your client. If you really want to understand the details of the protocol, then the wikipedia article is a good starting point, and provides links off to the various standards: https://en.wikipedia.org/wiki/Transport_Layer_Security The question you seem to be asking is "How do I implement SSL/TLS completely from scratch in .Net?". This is akin to building a website by first building a webserver - you don't do it, you just get one off the shelf. The question you should really be asking (on some .Net forum) is "How do I write a server *using* SSL/TLS in .Net?". I am not a .Net developer and can't really advise on this, except to say that a few minutes on google turned up this which looks like a good place to begin: http://msdn.microsoft.com/en-us/library/ms729700%28v=vs.110%29.aspx Matt ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
