How To Generate Ssh Key In Windows Using Git Bash

What is an SSH Central?

An SSH central is an access credential for the SSH (secure shell) network protocol. This authenticated and encrypted secure network protocol is used for remote communication between machines on an unsecured open network. SSH is used for remote file transfer, network management, and remote operating system access. The SSH acronym is besides used to draw a gear up of tools used to interact with the SSH protocol.

SSH uses a pair of keys to initiate a secure handshake betwixt remote parties. The key pair contains a public and private key. The individual vs public nomenclature tin exist confusing as they are both chosen keys. It is more than helpful to think of the public key as a "lock" and the individual fundamental as the "key". You give the public 'lock' to remote parties to encrypt or 'lock' data. This information is then opened with the 'private' key which you hold in a secure place.

How to Create an SSH Cardinal

SSH keys are generated through a public cardinal cryptographic algorithm, the almost common being RSA or DSA. At a very high level SSH keys are generated through a mathematical formula that takes 2 prime number numbers and a random seed variable to output the public and private key. This is a one-way formula that ensures the public cardinal can be derived from the private central but the private key cannot be derived from the public central.

SSH keys are created using a key generation tool. The SSH control line tool suite includes a keygen tool. Most git hosting providers offer guides on how to create an SSH Key.

Generate an SSH Key on Mac and Linux

Both OsX and Linux operating systems have comprehensive mod terminal applications that ship with the SSH suite installed. The process for creating an SSH primal is the same between them.

1. execute the following to begin the key cosmos

              ssh-keygen -t rsa -b 4096 -C "your_email@example.com"            

This command will create a new SSH key using the email as a characterization

ii. You volition then be prompted to "Enter a file in which to salve the key."
You tin can specify a file location or press "Enter" to accept the default file location.

              > Enter a file in which to save the central (/Users/yous/.ssh/id_rsa): [Press enter]            

3. The next prompt will inquire for a secure passphrase.
A passphrase will add together an additional layer of security to the SSH and will be required someday the SSH fundamental is used. If someone gains access to the computer that private keys are stored on, they could as well proceeds access to any system that uses that key. Adding a passphrase to keys volition prevent this scenario.

              > Enter passphrase (empty for no passphrase): [Type a passphrase]
> Enter same passphrase again: [Type passphrase again]
                          

At this bespeak, a new SSH cardinal volition accept been generated at the previously specified file path.

4. Add the new SSH fundamental to the ssh-agent

The ssh-agent is another program that is part of the SSH toolsuite. The ssh-agent is responsible for holding private keys. Recollect of it like a keychain. In addition to holding private keys it also brokers requests to sign SSH requests with the private keys and so that individual keys are never passed around unsecurly.

Before adding the new SSH key to the ssh-amanuensis first ensure the ssh-agent is running by executing:

              $ eval "$(ssh-agent -south)"
> Amanuensis pid 59566
                          

Once the ssh-amanuensis is running the following command will add together the new SSH key to the local SSH amanuensis.

              ssh-add -K /Users/you/.ssh/id_rsa            

The new SSH key is now registered and set to use!

Generate an SSH Key on Windows

Windows environments do not have a standard default unix vanquish. External beat programs will need to be installed for to have a complete keygen feel. The near straight forwards option is to employ Git Bash. Once Git Bash is installed the same steps for Linux and Mac tin be followed within the Git Fustigate shell.

Windows Linux Subsystem

Modern windows environments offer a windows linux subsystem. The windows linux subsystem offers a full linux vanquish within a traditional windows surroundings. If a linux subsystem is bachelor the same steps previously discussed for Linux and Mac tin be followed with in the windows linux subsystem.

Summary

SSH keys are used to authenticate secure connections. Post-obit this guide, you will be able to create and start using an SSH key. Git is capable of using SSH keys instead of traditional  password authentication when pushing or pulling to remote repositories. Modernistic hosted git solutions like Bitbucket support SSH cardinal authentication.
