PolarSSL - An Open Source SSL
The importance of secure socket layer is not a hidden truth on the Internet, SSL or secure socket layer provides an extra level of security for the confidential information. Now a days every important websites like E-commerce websites including online transactions are using SSL for user information security. If you dont have any idea about SSL than you can learn secure socket layer from our previous discussion.
What is PolarSSL
There are so many SSL services available on the Internet, but what makes PolarSSL a little different from others? The answer is simple and that PolarSSL is a light-weight open source cryptographic and SSL/TLS library written in C. PolarSSL is licensed according to the dual licensing model, making it available under the open source GPL version 2 as well as a commercial license.
It is easy to develop on an application that provides cryptographic facility between the user and the server. PolarSSL is written with embedded systems in mind and has been ported to a large number of environments, including Windows (32 and 64 bit), Linux, UNIXes, BSD's, OpenWRT, iPhone(iOS), XBox, Android and more. Chipsets supported includeIntel, ARM, PowerPC, MIPS and Motorola 68000.

However SSL provides some extra security and protection but as a user you must care about your information because there are different techniques available to break and crack SSL. An attacker might use backtrack like backtrack 5 to crack SSL.
