# Create an SSH key

## Generate a new key on your computer

To create a new SSH key, you can do so through the command line tool on a Linux machine (or using the Windows Subsystem for Linux)

Enter the following command to create a key:

```shell
ssh-keygen -t ed25519 -C "your_email@example.com"
```

In this example, the `ssh-keygen` command creates a new SSH key using the RSA algorithm with a 4096-bit key length.

The `-C` option adds a comment to the key, which is your email address in this case. The command will prompt you for a file in which to save the key, or accept the default location.
