# How to create a SSH key on Elementary OS 6.1 or any other Ubuntu-based Linux distribution via the terminal emulator?

---

## Check your operating system info

### LSB release tool

```plaintext
lsb_release -a
```

The `lsb_release -a` command is used to display detailed information about the Linux distribution on your system.

It stands for "Linux Standard Base release" and provides information such as the distribution's name, release number, codename, and more.

---

### Linux installed info

```plaintext
cat /etc/os-release
```

Running the `cat /etc/os-release` command in the terminal will display the contents of the `/etc/os-release` file, which contains information about the Linux distribution installed on your system.

---

## Generate SSH-key

```plaintext
ssh-keygen -t rsa -b 2048 -C "your email"
```

Replace "your email" with your actual email address.

The `-t` parameter specifies the type of key to create (in this case, RSA).

The `-b` parameter specifies the key length.

The `-C` parameter provides a comment (usually your email address) to help you identify the key later.

### Enter file

You can choose the path and filename.

If you just want to use the default name, press `Enter`, otherwise, provide the name/path of the file.

```plaintext
Enter file in which to save the key (/home/elitebughunter/.ssh/id_ed25519):
```

Output

I chose the following as the file name and location:

```plaintext
/home/elitebughunter/.ssh/ssh_key_mnt_elementary
```

---

## Enter passphrase

If you don't want to provide a password, just press `Enter`

```plaintext
Created directory '/home/elitebughunter/.ssh'.
Enter passphrase (empty for no passphrase):
```
