# Converting an SSH2 key to SSH public key format
<a name="convert-ssh2-public-key"></a>

 AWS Transfer Family only accepts SSH-formatted public keys. If you have an SSH2 public key, you need to convert it. An SSH2 public key has the following format:

```
---- BEGIN SSH2 PUBLIC KEY ----
Comment: "rsa-key-20160402"
AAAAB3NzaC1yc2EAAAABJQAAAgEAiL0jjDdFqK/kYThqKt7THrjABTPWvXmB3URI
:
:
---- END SSH2 PUBLIC KEY ----
```

An SSH public key has the following format:

```
ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAA...
```

Run the following command to convert an SSH2-formatted public key into an SSH-formatted public key. Replace *ssh2-key* with the name of your SSH2 key, and *ssh-key* with the name of your SSH key.

```
ssh-keygen -i -f ssh2-key.pub > ssh-key.pub
```
