GnuPG(GNU Privacy Guard或GPG)是一个以GNU通用公共许可证释出的开放源码用于加密或签名的软件,可用来取代PGP.大多数gpg软件仅支持命令行方式,一般人较难掌握.由于gpg软件开放源代码,很难隐藏后门,因此比pgp等商业软件安全. 1. 在实验机中创建alice和bob用户并设置密码 2. 切换到alice用户并生成密钥/公钥 3. 同样切换到bob用户也生成一遍 4. 将bob用户的公钥通过ASCII格式导出 5. 切换到用户alice然后导入bob的公钥并对文件进行…

所谓加解密就是一方以密钥加密,另一外收到文件后以相对应的密钥解密,从而获取原始文件.数字签名的过程:信息是通过普通未加密方式发送信息给对方的,只是在每条信息后面都会附加一坨字符(名曰:签名)(或信息与附加字符分别存放),这个签名是由程序根据发送者的私钥以及信息内容计算得出,接收者使用发送者的公钥就可以核对信息有无被篡改. 我们以Apache httpd server为例说明使用情况. 首先下载tar文件,httpd-2.2.31.tar.gz,同时tar包后也给出了PGP MD5 SHA1等加解…

PGP (Pretty Good Privacy) 是由 Phil Zimmermann 于 1991 开发的一个用于数据加密和数字签名的程序,由于被广泛应用以至于后来形成一个开放的标准 OpenPGP,而 GnuPG 则是实现了该标准的一个开源免费程序,本文将会简单介绍如何使用 GnuPG 管理钥匙.加密解密文件和电子邮件.数字签名文件和电子邮件等内容.篇幅有点长,不过内容是很简单的,可以一步一步跟着来.@ivarptr 一.加密和数字签名的简单原理 首先每个人使用程序生成地球上惟一的一对钥匙…
