Poznámky

Pokud je NotEmbedded certifikát v balíčku, musí aplikace, která ověřuje podpisy, poskytnout kopii certifikátu, aby bylo možné ověřit podpisy podepsané certifikátem.

InSignaturePart přidá dva informační prvky, <KeyName> a <KeyValue>, jako součást KeyInfo pole uloženého digitálního podpisu. Prvky <KeyName> a <KeyValue> se nezpracují jako součást ověřování podpisu, a proto nejsou zabezpečené před úpravami. Aplikace by neměly provádět žádné předpoklady týkající se platnosti těchto dvou prvků. Aby se zabránilo nezjištěným změnám a možným nejasnostem, měly by aplikace místo InSignaturePartpoužít InCertificatePart možnost . Možnost InCertificatePart neposkytuje nebo nezpřístupňuje ani <KeyName><KeyValue>nebo .
