I am receiving the following exception while receiving (synchronous SecureSocket.Receive) data from a socket. I do not receive this exception when using previous versions of your dll. What changed? How can I avoid this and still upgrade to your latest version? Version 1:0:13:692 of Org.Mentalis.Security.dll seems to work just fine. The version that produced the exception is 1:0:13:700.

Thanks.
Here's the text of the exception:

Could you upgrade to the latest version? We uploaded a new version a few days ago, and there's a good chance the error you're encountering is fixed.

I am facing the same problem. I created a TCP server based in the WebServer example. My client is writen in openssl, but when the client try to make a handshake, sametimes the seclib throws the SslException "The other side has sent a failure alert". I am with the latest version of the seclib

As Mentalis has not given me any response for my problem, I´ve given up this solution. Now I will migrate my application to .NET Framework 2.0. .NET 2.0 has support for SSL. And if I have any problem I can ask Microsoft, and have a good support.
