For my folks with some non-technical background, this is something related to what we discussed in our last class. The article listed here talks about the importance of Network Encryption. Although we don’t realize it but it plays a really important part every time we go online whether it be accessing bank information or browsing through websites. It goes on to explain what an Encryption Key is and the algorithms behind it along with the keys which the SSL encryption depends on. I will try to hunt down the article about the strong encryption method that requires a ton of computing power (I think it was RSA).
