如何使用Ssh Keygen生成4096位安全Ssh密钥

Ssh is secure protocol used to manage remote systems like Linux, BSD, UNIX, network devices event windows operating systems. The traffic between systems are encrypted. Ssh uses asymmetric keys in order to encrypt and made traffic invisible to the others those resides between systems in the network. The encryption power comes from key bit size or length. In this tutorial we will look how to create 4096 bit keys.

Ssh是安全协议，用于管理远程系统，例如Linux，BSD，UNIX，网络设备，事件Windows操作系统。 系统之间的流量已加密。 Ssh使用非对称密钥以便对驻留在网络系统之间的其他通信进行加密并使不可见的通信成为可能。 加密能力来自密钥位大小或长度。 在本教程中，我们将研究如何创建4096位密钥。

生成4098位密钥 (Generate 4098 Bit Key)

In this example we will generate very secure key. This key size will be 4096 bit. 4096 bit keys are a lot more secure than 2048 or 1024 bit keys. If we are not transferring big data we can use 4096 bit keys without a performance problem. We will use -b option in order to specify bit size to the ssh-keygen .

在此示例中，我们将生成非常安全的密钥。 密钥大小为4096位。 4096位密钥比2048位或1024位密钥安全得多。 如果我们不传输大数据，则可以使用4096位密钥，而不会出现性能问题。 我们将使用-b选项来为ssh-keygen指定位大小。

$ ssh-keygen  -b 4096

生成4096位DSA密钥(Generate 4096 Bit DSA Key)

RSA is very old and popular asymmetric encryption
