public class X509Extension

extends Object

Represents an X.509 extension. It is used to create X.509 extensions and pass them in a X509ExtensionSet during certificate generation.

Field Summary

protected boolean	critical
protected String	oid
protected byte[]	value

Constructor Summary

X509Extension(String oid)
Creates a X509Extension object with specified oid.

X509Extension(String oid, boolean critical, byte[] value)
Creates a X509Extension object with specified oid, critical property, and value.

X509Extension(String oid, byte[] value)
Creates a X509Extension object with specified oid and value.

Method Summary

static byte[]	getExtensionValue(X509Certificate cert, String oid) Returns the actual value of the extension.
String	getOid() Returns the oid of this extension.
byte[]	getValue() Returns the actual value of the extension (not octet string encoded)
boolean	isCritical() Determines whether or not this extension is critical.
void	setCritical(boolean critical) Sets the extension as critical or noncritical.
void	setOid(String oid) Sets the oid of this extension.
void	setValue(byte[] value) Sets the actual value of the extension (not octet string encoded).

Constructor Detail

X509Extension

public X509Extension(String oid)

Creates a X509Extension object with specified oid. The extension has no value and is marked as noncritical.

Parameters:

oid - the oid of the extension

X509Extension

public X509Extension(String oid,
                     byte[] value)

Creates a X509Extension object with specified oid and value. The extension is marked as noncritical.

Parameters:

oid - the oid of the extension

value - the actual value of the extension (not octet string encoded). The value can be null.

X509Extension

public X509Extension(String oid,
                     boolean critical,
                     byte[] value)

Creates a X509Extension object with specified oid, critical property, and value.

Parameters:

oid - the oid of the extension

critical - the critical value.

value - the actual value of the extension (not octet string encoded). The value can be null.

Method Detail

setOid

public void setOid(String oid)

Sets the oid of this extension.

Parameters:

oid - the oid of this extension. Cannot not null.

getOid

public String getOid()

Returns the oid of this extension.

Returns:

the oid of this extension. Always non-null.

setCritical

public void setCritical(boolean critical)

Sets the extension as critical or noncritical.

Parameters:

critical - the critical value.

isCritical

public boolean isCritical()

Determines whether or not this extension is critical.

Returns:

true if extension is critical, false otherwise.

setValue

public void setValue(byte[] value)

Sets the actual value of the extension (not octet string encoded).

Parameters:

value - the actual value of the extension. Can be null.

getValue

public byte[] getValue()

Returns the actual value of the extension (not octet string encoded)

Returns:

the actual value of the extension (not octet string encoded). Null if value not set.

getExtensionValue

public static byte[] getExtensionValue(X509Certificate cert,
                                       String oid)
                                throws IOException

Returns the actual value of the extension.

Parameters:

cert - the certificate that contains the extensions to retrieve.

oid - the oid of the extension to retrieve.

Returns:

the actual value of the extension (not octet string encoded)

Throws:

IOException - if decoding the extension fails.
