Hi,

we use Ciphermail as an encryption gateway and it works as aspected. Now we got a certificate from a custom to encrypt mails per S/MIME. This certificate has as key usage „nonRepudiation, digitalSignature“ and as extended key usage „smartcardLogin, emailProtection, clientAuth“, but we can’t use it for encryption. Is emailProtection not enough, does this certificate need as key usage „keyEncipherment“?

Regards

Christian
