Allow certificates signed using SHA-1 when issued by local trust anchors (deprecated)


DEPRECATED: This policy is deprecated. It is currently supported but will become obsolete in a future release.

When this setting is enabled Microsoft Edge allows connections secured by SHA-1 signed certificates so long as the the certificate chains to a locally-installed root certificate and is otherwise valid.

Note that this policy depends on the operating system (OS) certificate verification stack allowing SHA-1 signatures. If an OS update changes the OS handling of SHA-1 certificates this policy might no longer have effect. Further this policy is intended as a temporary workaround to give enterprises more time to move away from SHA-1. This policy will be removed in Microsoft Edge 92 releasing in mid 2021.If you don't set this policy or set it to false or the SHA-1 certificate chains to a publicly trusted certificate root then Microsoft Edge won't allow certificates signed by SHA-1.This policy is only available on Windows instances that are joined to a Microsoft Active Directory domain or Windows 10 Pro or Enterprise instances enrolled for device management.
