BasicConstraints object
[CAPICOM is a 32-bit only component that is available for use in the following operating systems: Windows Server 2008, Windows Vista, Windows XP. Instead, use the X509BasicConstraintsExtension Class in the System.Security.Cryptography.X509Certificates namespace.]
The BasicConstraints object represents the basic constraints extension of a certificate.
When to use
The BasicConstraints object is used to perform the following tasks:
- Determine whether the basic constraints extension is present.
- Determine whether the basic constraints extension is marked critical.
- Determine whether the certificate is constrained to certificate authorities.
- Determine whether the path length constraint is present and retrieve the path length constraint value.
Members
The BasicConstraints object has these types of members:
