实现这一点的一种常用机制是使用ssl加密。

A common mechanism for this is the use of SSL encryption.

由于所有数据都经过 SSH 隧道，因此受到 SSH 使用的当前加密机制的保护。

Since all data is now tunneled through SSH, it is secured by the current encryption mechanism in use by SSH.

可用各种方式组合这些机制，以便用各种加密技术建立各种安全模型。

These mechanisms can be combined in various ways to build a wide variety of security models using a variety of encryption technologies.

In Week 2 we'll look at things like cryptography and functions and the tools that by which you begin to assemble solutions to problems; in Week 3 we'll introduce what are generally ; known as algorithms and data structures; mechanisms by which you can solve problems more efficiently, effectively.

第2周,我们学习加密技术及其功能,还会学到一些操作工具,通过这些工具的使用来收集解决问题的办法,第3周,我们将介绍;,算法和数据结构,以及可以更有效地解决问题的机制。
