SSH

Create SSH key

-t specifies the key type

-b specifies the key size (in bits)

-C for comment to help identify your ssh key (optional)

-f for the file name where ssh key get saved

ssh-keygen -t rsa -b 4096 -C "<your email>" -f $env:USERPROFILE/.ssh/<key_name>

Add SSH key to SSH Agent

Add SSH private key to SSH Agent

ssh-add $env:USERPROFILE/.ssh/<key_name>

If previous command doesn’t work try the following or see this link

Check if SSH Agent service is running

Get-Service ssh-agent

Stop SSH Agent service

Stop-Service ssh-agent

Start SSH Agent service

Start-Service ssh-agent

Add SSH public key to the Github

Copy content of <key_name>.pub
Goto Settings > SSH and GPG keys > New SSH Key
Paste your copied public key and give it a Title of your choice

Create SSH Config file and add Host Entries

If config file not already exists then create one ($env:USERPROFILE/.ssh/config)

Host github.com-<username>
  HostName github.com
  User git
  IdentityFile C:/Users/<user name>/.ssh/<key_name>
  IdentitiesOnly yes

Host github.com-<username>

This is the hostname for which these settings apply.
Every time you connect to this host via SSH, the following configuration will be applied.
You can use different settings for other hosts (for example, for other servers).

HostName github.com

Specifies the actual hostname to connect to.

User git

GitHub requires the user to be specified as git for all SSH connections.

IdentityFile C:/Users/<user name>/.ssh/<key_name>

Specifies the path to your private SSH key, which will be used to authenticate to GitHub.

IdentitiesOnly yes

Causes SSH to only use the keys specified in the configuration file (via IdentityFile) and ignore any other keys that may be loaded into the SSH agent.
This helps if you have multiple keys and want to use a specific key for a specific host.

Cloning existing repository or adding remote for the local one

Clone existing repository

git clone git@github.com-<username>:<username>/<repo_name>.git

Add remote to local repository

git remote add origin git@github.com-<username>:<username>/<repo_name>.git

Change remote in local repository

git remote set-url origin git@github.com-<username>:<username>/<repo_name>.git

Finally

Don’t forget to specify user.name and user.email in every repository freshly cloned or existing before.

git config user.name "Your name"

git config user.email "your@email.com"

If you set GPG signing globally you can remove this for the local repository

git config commit.gpgSign false

If you have new GPG key you can set it for the local repository

git config user.signingkey <new-gpg-key-id>

Useful

Commands
