大家都知道，互联网上充斥着大量的明文传输方式，可以说绝对是不安全地带。那么，我们如何保证在不安全的互联网中更可靠的传输重要数据呢？个人认为最好的方式之一就是使用 GPG 工具进行加密。此文只是简单介绍了 GPG 的常规用法，重在推广和普及 GPG 加密工具，详细的使用请参见 GPG 手册。
RSA / DSA / ElGamal : 是指加密算法
GPG :（全称 GnuPG ) 是一款非对称加密(PGP)的免费软件，非对称加密方式简单讲就是指用公钥加密文件，用私钥解密文件。如果你想给谁发送加密信息，首先你要得到他的公钥，然后通过该公钥加密后传给他，对方利用自已的私钥就可解密并读取文件了。

Dear developers with a spare Chromebook lets inject a little personalization into your Crosh shell with custom fonts, the solarized theme, and extra secure shell options.
Also, keep in mind that the terms Chrosh, Chrosh Window, and Secure Shell all refer to various versions and extentions built around the ChromeOS terminal. Settings that affect the ChromeOS terminal are global.
