aws-sdk-java-v2-kms
AWS SDK for Java 2.x - AWS KMS (Key Management Service)
Overview
Provides AWS KMS patterns using AWS SDK for Java 2.x. Covers key management, encryption/decryption, envelope encryption, digital signatures, and Spring Boot integration.
Instructions
- Set Up IAM Permissions - Grant kms:* actions with least privilege
- Create KMS Client - Instantiate KmsClient with region and credentials
- Create Keys - Use createKey() → Verify key state is ENABLED before proceeding
- Set Key Policies - Define key usage permissions → Test access before production
- Encrypt Data - Use encrypt() for data <4KB; Verify ciphertext is not empty
- Envelope Encryption - For larger data, use generateDataKey() → Verify data key generation succeeded
- Digital Signatures - Create signing keys → Verify signatureValid=true after sign/verify
- Key Rotation - Enable auto-rotation → Confirm rotation schedule is active
