### Verify auto-encryption

> Note that auto-encryption only affects requests without S3 encryption headers. So, if a S3 client sends
> e.g. SSE-C headers, MinIO will encrypt the object with the key sent by the client and won't reach out to
> the configured KMS.

To verify auto-encryption, use the following `mc` command:

```
mc cp test.file myminio/bucket/

    @CsvSource({ "true, true, SMB311, 2", // DFS + Encryption
            "false, true, SMB311, 1", // Encryption only
            "true, false, SMB311, 1", // DFS only
            "false, false, SMB311, 0", // Neither
            "true, true, SMB210, 1", // DFS only (no encryption for SMB2)
            "false, true, SMB210, 0" // Neither (no encryption for SMB2)
    })

    /**
     * Test decrypt with an unsupported encryption type.
     */
    @Test
    void testDecryptUnsupportedType() {
        Key key = new KerberosKey(null, new byte[16], 99, 0);
        byte[] data = new byte[16];
        Exception exception = assertThrows(GeneralSecurityException.class, () -> KerberosEncData.decrypt(data, key, 99));
        assertEquals("Unsupported encryption type 99", exception.getMessage());
    }
