I recently got a new EV cert from SSL.com. The cert was cheap ($269/yr) and going through validation was easy but the YubiKey token didn't work and it took days of back-and-forth with support to finally get it working. To make up for sending a defective token, they gave me a free 3 year OV cert. Besides having to put in the PIN every time I sign with the EV, it all seemed to work out. Until I just tried to submit for attestation signing.
The signature algorithm for my new cert is sha384ECDSA. Partner Center rejected my package saying:
"For a Windows 10 submission, the input package and the included files must be signed with sha256 signature algorithm."
Does Partner Center really not support sha384ECDSA certificates? SSL.com is listed on Microsoft's own website as a provider for EV certs.
Has anyone else had this issue?
