Enable the SHA-1 Hashing Function

You can install certificates, signed with the SHA-1 hashing function in the Site Recovery Manager Appliance in case your environment requires it.

By default, the Site Recovery Manager server rejects installation of new certificates, which are signed with the SHA-1 hashing function. To install a certificate, signed with the SHA-1 hashing function, you must enable it in the Site Recovery Manager Appliance.
