oracle.security.crypto.cert.ext
Class NameConstraintsExtension

java.lang.Object
oracle.security.crypto.cert.X509Extension
oracle.security.crypto.cert.ext.NameConstraintsExtension

All Implemented Interfaces:

oracle.security.crypto.asn1.ASN1Object, oracle.security.crypto.util.Streamable

public class NameConstraintsExtension

extends X509Extension

Represents the certificate extension Name Constraints from RFC 2459. This extension must be critical in CA certificates.

Note that this implementation always sets the minimum subtree base distance to 0 (the default) and always omits the maximum.

Constructor Detail

NameConstraintsExtension

public NameConstraintsExtension()

Create a new extension with the appropriate OID type.

Note: An object created using this constructor may not be in a valid state. This constructor is intended primarily for use in conjunction with the X509Extension.input(java.io.InputStream) method.

NameConstraintsExtension

public NameConstraintsExtension(java.util.Vector permitted,
                                java.util.Vector excluded)

Creates a new extension with the given permitted and/or excluded subtree lists. The extension is critical.

Parameters:

permitted - A Vector of GeneralNames which are the permitted subtrees for this Name Constraints extension (may be null).

excluded - A Vector of GeneralNames which are the excluded subtrees for this Name Constraints extension (may be null).

NameConstraintsExtension

public NameConstraintsExtension(java.util.Vector permitted,
                                java.util.Vector excluded,
                                boolean critical)

Creates a new extension with the given permitted and/or excluded subtree lists and critical flag.

Parameters:

permitted - A Vector of GeneralNames which are the permitted subtrees for this Name Constraints extension (may be null).

excluded - A Vector of GeneralNames which are the excluded subtrees for this Name Constraints extension (may be null).

critical - true if this extension is critical, false otherwise.

NameConstraintsExtension

public NameConstraintsExtension(java.io.InputStream is)
                         throws java.io.IOException
