SSH, the secure shell, is often used to access remote Linux systems. But its authentication mechanism, where a private local key is paired with a public remote key, is used to secure all kinds of online services, from GitHub and Launchpad to Linux running on Microsoft’s Azure cloud.
Dec 07, 2019 SSH is short for Secure Shell.Secure Shell is a network protocol that provides administrators with a secure way (with encryption) to access a remote computer. It allows an administrator to log into virtual space server with an SSH key instead of a typical password. This eliminates the usual weakness of cracking passwords since SSHs almost can not be deciphered. 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. Generate 4098 Bit Key. In this example we will generate very secure key.
Generating these keys from Linux is easy, and thanks to Ubuntu on Windows, you can follow the same process from Windows 10. But even without Ubuntu, SSH keys can also be generated with the free and open source Windows application, PuTTy
Add Ssh Key
Over the following few steps, we’ll guide you through the process of generating SSH keys using both Ubuntu on Windows and PuTTY.
Requirements
All you need is a PC running Windows 10 and either of the following installed:
- The
puttygen.exe
executable from PuTTY
Ubuntu Generate Ssh Key With Email Password
If you don’t already have Ubuntu on Windows, take a look at our Install Ubuntu on Windows 10 tutorial.
