The PKCS#11 crypto plugin can be used to interface with a Hardware
Security Module (HSM) using the PKCS#11 protocol. Secrets are encrypted
(and decrypted on retrieval) by a project specific Key Encryption Key
(KEK) which resides in the HSM. Since a different KEK is used for each
project, and since the KEKs are stored inside an HSM (instead of in
plaintext in the configuration file) the PKCS#11 plugin is much more
secure than the simple crypto plugin. It is the most popular back end
amongst Barbican deployments.
(KEK). The KEK is protected (encrypted) with a Master KEK (MKEK). The MKEK
resides in the HSM along with a HMAC. Since the different KEK is used for
each project, and since the KEKs are stored inside a database in an encrypted
form (instead of a plaintext in the configuration file) the PKCS#11 plugin
is much more secure than the simple crypto plugin. It is the most popular
back end amongst Barbican deployments.
