Opmerkingen

Deze klasse is vergelijkbaar met een uitbreiding op de SubjectName of IssuerName eigenschap, de naam van de persoon of entiteit aan wie het certificaat wordt uitgegeven. X.500 is een internationale standaard voor gedistribueerde adreslijstservices. De DN-naam maakt gebruik van de volgende indeling:

[X500:/C=CountryCode/O=Organization/OU=OrganizationUnit/CN=CommonName]

De volgende veldlengtelimieten zijn van toepassing:

De volgende richtlijnen zijn van toepassing:

• Veldwaarden kunnen hoofdletters of kleine letters zijn.

• Scheidingstekens zijn slashmarkeringen (/) en moeten vóór de eerste waarde en tussen de volgende waarden worden weergegeven.

• Scheidingstekens kunnen worden gevolgd door een spatie.

Hier volgt een voorbeeld van een correct opgemaakte naam: [X500:/ C=US/ O=Microsoft/ OU=WGA/ CN=TedSt]
