如何在您的系统中安装GPG
如您使用我们支持的操作系统GPG可在xxx进行下载,如您使用windows版本请使用以下链接
在windows系统中,下载安装包后,安装本软件将十分简便。
在安装过程中,除安装基础GnuPG应用系统外,还会询问您需要的附加设置元件及特性。这些附加特性和元件在给出的安装过程中将会有所涉及。
如何在GPG中输入密钥
使用输入选项,可在公钥环中加入公开密钥
以下是输入公开密钥“gpg-lab.pub”的一个范例演示:
E:\>gpg --输入 gpg-lab.pub
gpg:密钥 6C14565D: 公开密钥 '网络安全和隐私 (Course key)' 输入
gpg: 处理过的数字总数: 1
gpg: 输入: 1
gpg: 没有找到被绝对信任的密钥
如何核实有效的密钥
有几个方法可以核实论证密钥的有效性。一种方法是合适指纹然后签名来验证密钥有效。我们可以使用指纹选项来检验密钥指纹的有效性。每个PGP密钥认证都有不同的指纹。另一种验证有效性的方法是信任第三方,让第三方来验证其有效性。例如,可以委托CA(认证机构)作为第三方认证。

· 如何在您的系统中安装GPG——How to install GPG on your system
GPG is available on xxxxxx for all supported operating systems and for windows version the link is xxxxxx.
In Windows, after downloading the installer, it is easy to install this software.
During the installation process the setup asks about the components and features that are needed to be installed in addition to the basic GnuPG application. The description of these additive features and components is also given at this step by the setup process.
· 如何在GPG中输入密钥——How to import keys into GPG
A public key can be added into the public key ring by using -import option
Following is an example of importing a public key “gpg-lab.pub”.
E:\>gpg --import gpg-lab.pub
gpg: key 6C14565D: public key 'Internet Security and Privacy (Course key)' imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: no ultimately trusted keys found
·如何验证密钥有效—— How to verify keys are valid
There are several ways [2] of verifying the validity of a key certificate. One way is to verify the fingerprints and then sign it to certify that the key is valid. We can check the fingerprints of key certificate by using -fingerprint option. Every PGP key certificate has unique fingerprint. The other way to set up the validity is to trust that a third individual has gone through the process of validating it. For example a CA (Certification Authority) can be used as a third individual.
Following is an example of finding the fingerprints of few keys used in this Lab.
E:\ >gpg --fingerprint
C:/Users/Tauseef/AppData/Roaming/gnupg/pubring.gpg
pub 1024D/FC610E36 2008-10-27 [expires: 2018-10-25]
Key fingerprint = 29EA C79A CF6E 9ECF C336 F4DD 9484 4BA1 FC61 0E36
uid Pehr S?derman (My current key)
sub 4096g/96ABEAF0 2008-10-27 [expires: 2018-10-25]
Fingerprint of this key is exactly the same as given in our lab instructions manual. Then in order to sign the key we need to edit it. A key can be edited by using -edit command and at the prompt using sign command.
·如何为密钥设置信任级别—— How to set trust levels on keys
We can set the trust level by using the -edit-key command. The complete format of this is “gpg --edit-key key id”. Following is an example.
