# Encryption and decryption action

From the module, you can start encryption or decryption of the selected partition, as well as temporarily disable BitLocker protection without decrypting the data.

### Partition encryption

{% stepper %}
{% step %}
Go to **IT Management > Encryption**.
{% endstep %}

{% step %}
Locate the computer and the partition you want to encrypt.

{% endstep %}

{% step %}
Click **Encrypt**.

{% endstep %}

{% step %}
Select the default configuration or specify the encryption and protection methods manually.

{% endstep %}

{% step %}
Save the configuration and start the task.
{% endstep %}

{% step %}
If TPM protection with a PIN or password is selected, the end user will receive a prompt on the computer. They must enter the required PIN or password so that the process can continue.

{% endstep %}
{% endstepper %}

### Encryption method

By default, the system selects the strongest method supported by the computer.

In manual settings, you can specify one or more methods:

* **XTS-AES-256** - requires Windows 10 or later,
* **XTS-AES-128** - requires Windows 10 or later,
* **AES-256**,
* **AES-128**.

If you select multiple methods, BitLocker will apply the strongest method supported by the computer.

### Protection method

By default, the system uses protection **TPM without a PIN**, if the computer supports it.

The following are available in manual settings:

| Method     | Action                                       |
| ---------- | -------------------------------------------- |
| TPM + PIN  | Requires TPM and the user to enter a PIN.    |
| TPM        | Uses the TPM without additional user action. |
| Passphrase | Requires the user to enter a password.       |

If you select multiple protection methods, BitLocker will apply the strongest method supported by the computer.

{% hint style="warning" %}
Selecting TPM protection with a PIN or password requires user action on the computer. The user cannot skip or close this step.
{% endhint %}

### Partition decryption

{% stepper %}
{% step %}
Go to **IT Management > Encryption**.
{% endstep %}

{% step %}
Locate the computer and the encrypted partition.
{% endstep %}

{% step %}
Click **Decrypt**.
{% endstep %}

{% step %}
Confirm that you want to start the operation.
{% endstep %}
{% endstepper %}

The decryption process cannot be canceled after it has started. If the computer is turned off or loses power, BitLocker will resume the process after the device is restarted.

### Temporarily disable BitLocker protection

Options **Disable** and **Enable** apply to BitLocker protection, not to disk encryption itself.

Disabling protection:

* does not decrypt the data,
* temporarily suspends BitLocker protection,
* may be useful during service work or device configuration changes.

To secure the partition again, use the option **Enable**.

{% hint style="info" %}
If you want to permanently remove encryption from the partition, use the option **Decrypt**, not **Disable**.
{% endhint %}

### FAQ

<details>

<summary><strong>Which encryption method is used by default?</strong></summary>

The system selects the strongest method supported by the computer.

</details>

<details>

<summary><strong>Does the user need to enter a PIN or password?</strong></summary>

Yes, if during configuration you choose protection **TPM + PIN** or **Passphrase**.

</details>

<details>

<summary><strong>Can I cancel a decryption process that has started?</strong></summary>

No. Once the decryption process has started, it cannot be canceled.

</details>

<details>

<summary><strong>How does the Disable option differ from Decrypt?</strong></summary>

The option **Disable** temporarily suspends BitLocker protection, but the data remain encrypted. The option **Decrypt** removes encryption from the partition.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://eaclouddoc.eauditor.eu/eacloud-docs-en/features/it-management/disk-encryption/encryption-and-decryption-action.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
