public abstract class AbstractX509Extension
extends java.lang.Object

Represents and creates an X509 V3 extensions. The concrete extensions are subclasses of this class and must (!) implement the IDENTIFIER String constant and a public (!) constructor that takes a DERSequence.

Constructor Detail

AbstractX509Extension

public AbstractX509Extension(java.lang.String a_identifier,
                             boolean a_critical,
                             byte[] a_value)

Create a new X509 V3 extension.

Parameters:

a_identifier - the identifier of this extension

a_critical - boolean

a_value - the extension's value

AbstractX509Extension

public AbstractX509Extension(org.bouncycastle.asn1.DERSequence a_extension)

Creates an extension from a BouncyCastle DER sequence. For internal use only. Each subclass must contain this constructor in the following form:

 X509UnknownExtension(DERSequence a_extension)
 {
    super(a_extension);
 }
 

Parameters:

a_extension - a DERSequence

Method Detail

getInstance

static AbstractX509Extension getInstance(org.bouncycastle.asn1.DERSequence a_extension)

Creates an extension from a BouncyCastle DER sequence. For internal use only.

Parameters:

a_extension - a DERSequence

Returns:

a X509Extension

getName

public abstract java.lang.String getName()

Returns the human-readable name of this extension.

Returns:

the human-readable name of this extension

isCritical

public final boolean isCritical()

Returns if the extension is critical.

Returns:

true if the extension is critical; false otherwise

getIdentifier

public final java.lang.String getIdentifier()

Returns the identifier of this extension.

Returns:

the identifier of this extension

getDEROctets

public final byte[] getDEROctets()

Returns the DER value of this extension in a single byte array.

Returns:

the DER value of this extension in a single byte array

hashCode

public final int hashCode()

The hash code is derived from the identifier.

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code

equals

public final boolean equals(java.lang.Object a_object)

Two extensions are equal if their identifiers are equal.

Overrides:

equals in class java.lang.Object

Parameters:

a_object - an Object

Returns:

true if the object is an extension and their identifiers are equal; false otherwise

getValues

public abstract java.util.Vector getValues()

This method returns all values of this extension in separated String objects. The values should be human readable.

Returns:

all values of this extension

toString

public final java.lang.String toString()

Returns the name of this extension.

Overrides:

toString in class java.lang.Object

Returns:

the name of this extension

getBCExtension

final org.bouncycastle.asn1.DERSequence getBCExtension()
