@Generated(value="jsii-pacmak/1.104.0 (build e79254c)", date="2025-01-15T21:09:17.813Z") @Stability(Stable) public class CfnKeyPair extends CfnResource implements IInspectable, ITaggable
Specifies a key pair for use with an Amazon Elastic Compute Cloud instance as follows:.

  • To import an existing key pair, include the PublicKeyMaterial property.
  • To create a new key pair, omit the PublicKeyMaterial property.

When you import an existing key pair, you specify the public key material for the key. We assume that you have the private key material for the key. AWS CloudFormation does not create or return the private key material when you import a key pair.

When you create a new key pair, the private key is saved to AWS Systems Manager Parameter Store, using a parameter with the following name: /ec2/keypair/{key_pair_id} . For more information about retrieving private key, and the required permissions, see Create a key pair using AWS CloudFormation in the Amazon EC2 User Guide .

When AWS CloudFormation deletes a key pair that was created or imported by a stack, it also deletes the parameter that was used to store the private key material in Parameter Store.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.ec2.*;
 CfnKeyPair cfnKeyPair = CfnKeyPair.Builder.create(this, "MyCfnKeyPair")
         .keyName("keyName")
         // the properties below are optional
         .keyFormat("keyFormat")
         .keyType("keyType")
         .publicKeyMaterial("publicKeyMaterial")
         .tags(List.of(CfnTag.builder()
                 .key("key")
                 .value("value")
                 .build()))
         .build();

    • getAttrKeyFingerprint

      @Stability(Stable) @NotNull public String getAttrKeyFingerprint()
      If you created the key pair using Amazon EC2:.

      • For RSA key pairs, the key fingerprint is the SHA-1 digest of the DER encoded private key.
      • For ED25519 key pairs, the key fingerprint is the base64-encoded SHA-256 digest, which is the default for OpenSSH, starting with OpenSSH 6.8 .

      If you imported the key pair to Amazon EC2:

      • For RSA key pairs, the key fingerprint is the MD5 public key fingerprint as specified in section 4 of RFC 4716.
      • For ED25519 key pairs, the key fingerprint is the base64-encoded SHA-256 digest, which is the default for OpenSSH, starting with OpenSSH 6.8 .
