| 7 | <p>There are some limitations the user needs to be aware of when using this feature: </p>
|
|---|
| 8 | <ul>
|
|---|
| 9 | <li>
|
|---|
| 10 | <p>Exporting appliances containing an encrypted VM is not possible, because the OVF specification does not
|
|---|
| 11 | support this. The VM is therefore decrypted during export. </p>
|
|---|
| 12 | </li>
|
|---|
| 13 | <li>
|
|---|
| 14 | <p>The DEK is kept in memory while the VM is running to be able to encrypt and decrypt VM data. While this
|
|---|
| 15 | should be obvious the user needs to be aware of this because an attacker might be able to extract the key on a
|
|---|
| 16 | compromised host and decrypt the data. </p>
|
|---|
| 17 | </li>
|
|---|
| 18 | <li>
|
|---|
| 19 | <p>When encrypting or decrypting the VM, the password is passed in clear text using the <ph
|
|---|
| 20 | conkeyref="vbox-conkeyref-phrases/product-name"/> API. This needs to be kept in mind, especially when using
|
|---|
| 21 | third party API clients which make use of the web service where the password might be transmitted over the
|
|---|
| 22 | network. The use of HTTPS is mandatory in such a case. </p>
|

| 23 | </li>
|

| 24 | </ul>
