# Generate a Key Pair for SSH
|
|
|
|
This page describes how to use `ssh-keygen`
|
|
to generate a public/private RSA key pair
|
|
that can be used with SSH.
|
|
(Note: `ssh-keygen` is found on most Linux and Unix-like
|
|
operating systems; if you're using Windows,
|
|
then you'll have to use another tool,
|
|
such as PuTTYgen.)
|
|
|
|
By convention, SSH key pairs get stored in the `~/.ssh/` directory.
|
|
Check what keys you already have there:
|
|
```text
|
|
ls -1 ~/.ssh/
|
|
```
|
|
|
|
Next, make up a new key pair name (called `<name>` below).
|
|
Here are some ideas:
|
|
|
|
* `aws-bdb-2`
|
|
* `tim-bdb-azure`
|
|
* `chris-bcdb-key`
|
|
|
|
Next, generate a public/private RSA key pair with that name:
|
|
```text
|
|
ssh-keygen -t rsa -C "<name>" -f ~/.ssh/<name>
|
|
```
|
|
|
|
It will ask you for a passphrase.
|
|
You can use whatever passphrase you like, but don't lose it.
|
|
Two keys (files) will be created in `~/.ssh/`:
|
|
|
|
1. `~/.ssh/<name>.pub` is the public key
|
|
2. `~/.ssh/<name>` is the private key
