(TCP/IP, C#) SSL(One-time-key) type of security?

9 May 2014 by Dimitri Nostarik

Hello Codeproject,I'm looking to create a secure connection between a server and a client. The client will be sending valuable information, and because it's valuable I wish to secure the information transferred from one another.A type of security that does what I mean is SSL. Basically...

(TCP/IP, C#) SSL(One-time-key) type of security?

9 May 2014 by Rob Philpott

Sounds like SSL is what you want. It does two things for you, encrypts the data sent back and forth so it can't (allegedly) be any use to anyone eavesdropping but it also confirms the server is the real server and not some imposter.SSL exchanges a symmetric key using asymmetric encryption -...
