In case of certificate-based authentication, MinIO has to map the client-provided certificate to an S3 policy. MinIO does this via the subject common name field of the X.509 certificate. So, MinIO will associate a certificate with a subject `CN = foobar` to a S3 policy named `foobar`.

The following self-signed certificate is issued for `consoleAdmin`. So, MinIO would associate it with the pre-defined `consoleAdmin` policy.

## 2. Enable bucket lifecycle configuration

- Create a bucket lifecycle configuration which expires the objects under the prefix `old/` on `2020-01-01T00:00:00.000Z` date and the objects under `temp/` after 7 days.
- Enable bucket lifecycle configuration using `mc`:

```sh
$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {
            "Expiration": {

Traditional retrieval of objects is always as whole entities, i.e GetObject for a 5 GiB object, will always return 5 GiB of data. S3 Select API allows us to retrieve a subset of data by using simple SQL expressions. By using Select API to retrieve only the data needed by the application, drastic performance improvements can be achieved.

You can use the Select API to query objects with following features:

      val subjectKeyPair = keyPair ?: generateKeyPair()
      val subjectPublicKeyInfo =
        CertificateAdapters.subjectPublicKeyInfo.fromDer(
          subjectKeyPair.public.encoded.toByteString(),
        )
      val subject: List<List<AttributeTypeAndValue>> = subject()
