# Vault Enterprise HSM Support
|
|
|
|
|
|
|
|
HSM support is a feature of [Vault
|
|
|
|
Enterprise](https://www.hashicorp.com/vault.html) that takes advantage of HSMs
|
2018-05-13 20:39:22 +00:00
|
|
|
to provide three pieces of special functionality:
|
2017-03-15 18:31:14 +00:00
|
|
|
|
|
|
|
* Master Key Wrapping: Vault protects its master key by transiting it through
|
|
|
|
the HSM for encryption rather than splitting into key shares
|
2018-05-13 20:39:22 +00:00
|
|
|
* Automatic Unsealing: Vault stores its HSM-wrapped master key in storage,
|
2017-03-15 18:31:14 +00:00
|
|
|
allowing for automatic unsealing
|
2018-05-13 20:39:22 +00:00
|
|
|
* [Seal Wrapping](/docs/enterprise/sealwrap/index.html) to provide FIPS
|
|
|
|
KeyStorage-conforming functionality for Critical Security Parameters
|
2019-12-02 18:04:05 +00:00
|
|
|
* [Entropy Augmentation](/docs/enterprise/entropy-augmentation/index.html) to
|
|
|
|
allow Vault to sample entropy from an external cryptographic module.

|
|
|
HSM support is available for devices that support PKCS#11 version 2.20+
|
|
|
|
interfaces and provide integration libraries, and is currently available for
|
|
|
|
linux/amd64 platforms only. It has successfully been tested against many
|
|
|
|
different vendor HSMs; HSMs that provide only subsets of the full PKCS#11
|
|
|
|
specification can usually be supported but it depends on available
|
|
|
|
cryptographic mechanisms.

|
2018-05-13 20:39:22 +00:00
|
|
|
Please note however that configuration details, flags, and supported features
|
|
|
|
within PKCS#11 vary depending on HSM model and configuration. Consult your
|
|
|
|
HSM's documentation for more details.
|

|
|
|
|
|
|
|
Some parts of Vault work differently when using an HSM. Please see the
|
2018-05-13 20:39:22 +00:00
|
|
|
[Behavioral Changes](/docs/enterprise/hsm/behavior.html) page for
|
|
|
|
important information on these differences.

|
|
|
|
2018-05-13 20:39:22 +00:00
|
|
|
The [Configuration](/docs/configuration/seal/pkcs11.html) page contains
|
|
|
|
configuration information.

2018-05-13 20:39:22 +00:00
|
|
|
Finally, the [Security](/docs/enterprise/hsm/security.html) page contains
|
|
|
|
information about deploying Vault's HSM support in a secure fashion.
