For deb or apt based distributions we can install GPG with the following command for gnupg package.

对于基于deb或apt的发行版，我们可以使用gnupg软件包的以下命令安装GPG。

For rpm or yum based distributions we can install GPG with the following command.

对于基于rpm或yum的发行版，我们可以使用以下命令安装GPG。

Now we will start with creating Private and Public Keys. As we know Public Cryptography provides two keys where the private key is a secret key which should be protected accordingly. The public key is as its name suggests open to everyone we want to collaborate with. So we need these keys. we can create them with the --gen-key option like below.

现在，我们将从创建私钥和公钥开始。 众所周知，公共密码学提供了两个密钥，其中私有密钥是秘密密钥，应相应地对其进行保护。 顾名思义，公钥向我们要与之合作的所有人开放。 因此，我们需要这些键。 我们可以使用--gen-key选项创建它们，如下所示。

This command will ask us some questions like below.

该命令将向我们询问一些类似以下的问题。

We can list-keys created and saved in the current system with the --fingerprint option. We should provide some search terms to this option like the email address or individual name etc. In this example, we will search with the email address ibaydan.
