Create a Key Pair
You must specify a key pair when you launch an EC2 instance and then specify the private key of the key pair when you connect to the instance. You can create a key pair or use an existing key pair that you’ve used when launching other instances. For more information, see Amazon EC2 Key Pairs
-
Create and initialize a CreateKeyPairRequest instance. Use the withKeyName
method to set the key pair name, as follows: CreateKeyPairRequest createKeyPairRequest = new CreateKeyPairRequest(); createKeyPairRequest.withKeyName(keyName);
Important
Key pair names must be unique. If you attempt to create a key pair with the same key name as an existing key pair, you’ll get an exception.
-
Pass the request object to the createKeyPair
method. The method returns a CreateKeyPairResult instance, as follows: CreateKeyPairResult createKeyPairResult = amazonEC2Client.createKeyPair(createKeyPairRequest);
-
Call the result object’s getKeyPair
method to obtain a KeyPair object. Call the KeyPair
object’s getKeyMaterialmethod to obtain the unencrypted PEM-encoded private key, as follows: KeyPair keyPair = new KeyPair(); keyPair = createKeyPairResult.getKeyPair(); String privateKey = keyPair.getKeyMaterial();
