These credentials can now be used to perform MinIO API operations, these credentials automatically expire in 1hr. To understand more about credential expiry duration and client grants STS API read further [here](https://github.com/minio/minio/blob/master/docs/sts/client-grants.md).

- MinIO tries to find a policy that matches the `CN` of the client certificate.
- MinIO returns temp. S3 credentials associated to the found policy.

The returned credentials expiry after a certain period of time that can be configured via `&DurationSeconds=3600`. By default, the STS credentials are valid for 1 hour. The minimum expiration allowed is 15 minutes.

* Inside the `certs` directory, the private key must by named `private.key` and the public key must be named `public.crt`.
* A certificate signed by a CA contains information about the issued identity (e.g. name, expiry, public key) and any intermediate certificates. The root CA is not included.
