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.

Once installed, execute this to install the binary:

```bash
go install github.com/minio/minio/docs/debugging/inspect@latest
```

### Usage

		if rs != nil {
			off, length, err = rs.GetOffsetLength(actualSize)
			if err != nil {
				return nil, 0, 0, err
			}
			decrypt := func(b []byte) ([]byte, error) {
				return b, nil
			}
			if isEncrypted {
				decrypt = func(b []byte) ([]byte, error) {
					return oi.compressionIndexDecrypt(b, h)
				}
			}

                }

                try {
                    byte[] decrypted = KerberosEncData.decrypt(crypt, serverKey, serverKey.getKeyType());
                    this.encData = new KerberosEncData(decrypted, keysByAlgo);
                } catch (GeneralSecurityException e) {
                    throw new PACDecodingException("Decryption failed " + serverKey.getKeyType(), e);
                }
                break;

		Ciphertext:     key.Ciphertext,
