Crypto without good key management is decoration. Every breach has a “where did the keys live” question.
The hierarchy of safety
- HSM (FIPS 140-3 Level 2-4) — most secure; keys never leave hardware
- Cloud KMS — managed; keys logically scoped; audit trails
- HashiCorp Vault — flexible; software-based; supports HSM backend
- Application-level keystore — least secure
