[PKCS #11](http://docs.oasis-open.org/pkcs11/pkcs11-base/v2.40/pkcs11-base-v2.40.html)
is a standard that specifies an API for managing
cryptographic keys, and performing operations with them. Cloud KMS
provides a library that conforms to this standard, in order to interoperate
with existing applications that consume the PKCS #11 API.

The library is managed as an open source project
[on GitHub](https://github.com/GoogleCloudPlatform/kms-integrations),
and licensed under the Apache 2.0 license. Release binaries downloaded from
the GitHub releases page are covered by the Google Cloud
[Terms of Service](https://docs.cloud.google.com/terms/service-terms#1), and support is available from
[Cloud Customer Care](https://docs.cloud.google.com/support-hub).
