[cabfpub] Updates to Microsoft SHA-1 deprecation

Windows enforcement dates (i.e., date at which SHA-1 certificates will be rejected by Windows) only apply to SSL and code signing certificates. All other types of certificates will be rejected on Windows side when SHA-1 pre-image attacks are deemed feasible by Microsoft.

Hi Anoosh,

Thank you for the update.

I don't think the policy for S/MIME certificates has been stated. I see some discussion in the comments. Could you also advise how the SHA-1 deprecation policy applies to S/MIME certificates.

Thanks, Bruce.
