SSL and certificates

Increasingly IT-security plays a larger role, especially in handling sensitive data. In any case user name and passwords are parts of it. To protect these SSL - Secure Socket Layer goes into action when transmitting files between WWW-Browser and WWW-Server.

What is SSL and how does it work?

SSL is a transmission protocol with hybrid encryption, i.e. to encrypt transmitted files a symmetric procedure (both sides, Browser and server use the same key) is used. An asymmetric procedure is used to exchange the necessary key.
