I follow the instruction and create a .csr file in "Certificate Signing Request" of KN1132V.

After I provide the .csr file to CA organization to create the certificate, I get lots of certificate files.

I am not sure what kind of certificate that ATEN KVM could support.

ATEN KVM only could support X.509 with public key.

PKCS7 will be the certificate that ATEN KVM could support.
