# Prepare your instance for GlideEncrypter deprecation

Use an instance scan script to find and remove GlideEncrypter API calls on your instance. Removing these calls is a necessary step in deprecating 3DES encryption on your instance.

## Before you begin

Role required: admin

The GlideEncrypter API is planned for deprecation as of the Zurich release of ServiceNow. Removing GlideEncrypter calls from your script is also a necessary step before deprecating 3DES encryption on your instance.

## Procedure

1.  Navigate to **All** > **Instance Scan** > **Suites**.

2.  In the **Suites** list, select **GlideEncrypter** to identify the records with GlideEncrypter usages.

3.  In the **Suites** record, select **Execute Suite Scan**.

4.  In the **Scan Suites Now** window, select **Full Instance**, then select **Execute Scan**.

    The suite scan executes. During the scan execution a **Execute Test Scan**, a window displays the progress of the scan.\[Omitted image "scan-progress.png"\] Alt text: Scan progress window

    **Note:** This scan checks only records that have been created or modified by the customer.

5.  When the scan is complete, select **Go to Result** to view the **Scan Result** record.

6.  In the **Scan Result** record, select the **Count** field on the **Scan Findings** list to navigate to a record.

    \[Omitted image "scan-progress-3.png"\] Alt text: Completed scan

7.  Modify any scripts in the record that uses the **GlideEncrypter** API.

    For details on alternatives to **GlideEncrypter**, see [Alternatives to deprecated GlideEncrypter APIs](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1320986).

    **Note:** You do not need to modify base system \(out-of-box\) records if you have not made any changes to them. These records are handled by ServiceNow.

8.  After removing **GlideEncrypter** calls from your scripts, run the scan again to ensure that there are no remaining calls to the API.
