- Auto Unsealing with HSM: Enables Vault to decrypt its master key automatically using an HSM, eliminating manual unseal operations.
- Seal Wrap: Leverages the HSM to wrap and protect Vault’s storage encryption keys, ensuring data-at-rest remains secure.
HashiCorp does not provide an HSM for certification candidates. If you have access to an on-premises or cloud-based HSM, follow the official Vault PKCS#11 seal documentation to configure auto unsealing and seal wrap.
