  an older version you must use an `S3 API client` such as [`mc`](https://github.com/minio/mc).

- All features currently used by your buckets will work as is without any changes
  - SSE (Server Side Encryption)
  - Replication (Server Side Replication)

## Prerequisites

- It is assumed you have users created and configured with relevant access policies, to start with

     * Creates a byte array representing a Kerberos ticket for testing purposes.
     * @param version Kerberos version
     * @param realm Server realm
     * @param principalName Server principal name
     * @param encType Encryption type
     * @param encryptedData Encrypted data
     * @param unknownTag Optional unknown tag number to test error handling
     * @return A byte array representing the ticket
     * @throws IOException on encoding error

mc: The decryption key will ONLY be shown here. It cannot be recovered.
mc: The encrypted file can safely be shared without the decryption key.
mc: Even with the decryption key, data stored with encryption cannot be accessed.
```

This file can be decrypted using the decryption tool below:

### Installing decryption tool

To install, [Go](https://golang.org/dl/) must be installed.

            assertEquals(Smb2TreeConnectResponse.SMB2_SHAREFLAG_ENCRYPT_DATA, response.getShareFlags(), "Should handle encryption flag");
