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

OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 91. If you enable this policy, Microsoft Edge allows connections secured by SHA-1 signed certificates so long as the certificate chains to a locally installed root certificate and is otherwise valid. 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 disable or don't configure this policy, or if 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 available only on Windows instances that are joined to a Microsoft Active Directory domain, Windows 10 Pro or Enterprise instances that enrolled for device management, or macOS instances that are that are managed via MDM or joined to a domain via MCX.
