Overview
What This Skill Does
Java SDK for managing cryptographic keys in Azure Key Vault and Managed HSM. Supports RSA, EC, and symmetric key types with HSM backing options. Handles the full key lifecycle including creation, rotation, backup, and deletion, plus cryptographic operations like encrypt, decrypt, sign, verify, and key wrapping.
Application
When to use this Skill
- Configuring integration settings for custom agent workflows.
- Optimizing query execution and response latency in production.
- Developing clean, standard-compliant implementations for enterprise services.
- Troubleshooting connection timeouts and authentication handshakes.
- Monitoring API rate limits and execution pipelines programmatically.
