* `name` - (Required) A unique name for the keypair. Changing this creates a new keypair.
* `public_key` - (Optional) A pregenerated OpenSSH-formatted public key. Changing this creates a new keypair. If a public key is not specified, then a public/private key pair will be automatically generated. If a pair is created, then destroying this resource means you will lose access to that keypair forever.

### Attributes Reference

}
```

### Argument Reference

* `region` - (Optional) The region name to which the keypair to query belongs.
* `name` - (Required) A unique name for the keypair. Changing this creates a new keypair.
* `public_key` - (Optional) A pregenerated OpenSSH-formatted public key. Changing this creates a new keypair. If a public key is not specified, then a public/private key pair will be automatically generated. If a pair is created, then destroying this resource means you will lose access to that keypair forever.

### Attributes Reference
