All base system scripts have been updated and no longer use calls to this API. - **Upgraded instances** Zurich instances that have been upgraded from a previous release are still able to use the legacy GlideEncypter API, but the API has been updated to use AES256-GCM encryption via the [Key Management Framework](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-security/encryption.md). This change replaces the use of the legacy 3DES encryption standard to comply with NIST guidelines, while allowing any scripts still using GlideEncrypter to operate. ## Enable or disable GlideEncrypter The availability of GlideEncrypter is controlled by the **glide.security.glideencrypter.allow** system property. This system property is set to **false** by default in new Zurich instances and can’t be updated. In instances upgraded to Zurich, this property can be changed by administrators with the security\_admin role.
Value Behavior
true When true, GlideEncypter can still be called in scripts, but uses the AES256-GCM encryption via the [Key Management Framework](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-security/encryption.md).
false When false, GlideEncrypter calls return `null`, and administrators see this error:``` Unsupported call to GlideEncrypter. Details: GlideEncrypter is deprecated and now returns null, please refer [KB1320986](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1320986) ```
