Constructor Detail

CertificateContainer

public CertificateContainer(CertPath a_certPath,
                            int a_certificateType,
                            boolean a_certificateNeedsVerification)

Creates a new instance of CertificateContainer. Only instances of CertificateStore should call this constructor.

Parameters:

a_certificate - The certificate for which the container is built.

a_certificateType - The type of the certificate.

a_certificateNeedsVerification - Whether this certificate is only valid within the certificate store, if it can be verified against an active root certificate from the store.

CertificateContainer

public CertificateContainer(org.w3c.dom.Element a_certificateContainerNode)
                     throws java.lang.Exception

Creates a new instance of CertificateContainer. Only instances of CertificateStore should call this constructor. Certificates loaded via this constructor cannot be removed automatically from the certifcate store and will be persistent (isOnlyHardRemovable() will return true).

Parameters:

a_certificateContainerNode - The XML node to load the settings from ('CertificateContainer' node). Such a node can be created by calling toXmlElement().

Throws:

java.lang.Exception

Method Detail

getCertificate

public JAPCertificate getCertificate()

Returns the corresponding certificate for this CertificateContainer.

Returns:

The certificate where the settings stored within this container are belonging to.

getCertPath

public CertPath getCertPath()

setParentCertificate

public void setParentCertificate(JAPCertificate a_parentCertificate)

Changes the parent certificate (the certificate against which verification of this certificate was successful) of this certificate. This value will be null, if the certificate store doesn't contain a matching parent certificate (or if that certificate is not active). This value is not meaningful, if this certificate doesn't need verification.

Parameters:

a_parentCertificate - The parent certificate of this certificate (maybe null).

getParentCertificate

public JAPCertificate getParentCertificate()

Returns the parent certificate (the certificate against which verification of this certificate was successful) of this certificate. This value will be null, if the certificate store doesn't contain a matching parent certificate (or if that certificate is not active). This value is not meaningful, if this certificate doesn't need verification.

Returns:

a_parentCertificate The parent certificate of this certificate (maybe null).

getCertificateType

public int getCertificateType()

Returns the certificate type of this certificate. See the CERTIFICATE_TYPE constants within JAPCertificate.

Returns:

The certificate type of this certificate.

getCertificateNeedsVerification

public boolean getCertificateNeedsVerification()

Returns, whether this certificate needs verification by a parent certificate in order to get activated within the certificate store.

Returns:

Whether this certificate needs to be verified against a root certificate in order to get activated within the certificate store.

isAvailable

public boolean isAvailable()

Returns whether this certificate is activated within the certificate store. Only activated certificates should be used to verify signatures and other certificates. A certificate is activated, if it is enabled and can be verified against a root certificate from the certificate store (only if the certificate requires verification, see getCertificateNeedsVerification() ).

Returns:

Whether this certificate is active within the certificate store.

isEnabled

public boolean isEnabled()

Stores, whether this certificate is enabled within the certificate store.

Returns:

Whether this certificate is enabled within the certificate store.

setEnabled

public void setEnabled(boolean a_enabled)

Changes the value which stores, whether this certificate is enabled within the certificate store.

Parameters:

a_enabled - Whether this certificate shall be enabled within the certificate store.

enableOnlyHardRemovable

public void enableOnlyHardRemovable()

Disables the possibility of removing the certificate automatically from the certificate store. Then the certificate can only be removed from the store by calling removeCertificate(). Without calling this method, the certificate will be removed also from the certificate store automatically, if there are no more active locks on the certificate (removeCertificateLock() was called for all locks on the certificate). Also the certificate will be persistent (included in the XML structure created by the certificate store) any more, if this method is called (persistence wouldn't make sense for automatically removable certificates).

isOnlyHardRemovable

public boolean isOnlyHardRemovable()

Returns, whether the certificate can only be removed from the certificate store by calling the removeCertificate() method. If this value is false, the certificate will be removed also from the certificate store automatically, if there are no more active locks on the certificate (removeCertificateLock() was called for all locks on the certificate). Also the certificate will be persistent (included in the XML structure created by the certificate store) only, if this value is true (persistence wouldn't make sense for automatically removable certificates) and if it is removable (otherwise it is expected to be reloaded on hte next start).

Returns:

Whether the certificate can only be removed from the certificate store by calling removeCertificate() and also whether the certificate will be persistent.

enableNotRemovable

public void enableNotRemovable()

This certifcate is not removeable - this is a workaround for default certificates

isNotRemovable

public boolean isNotRemovable()

getLockList

public java.util.Vector getLockList()

Returns the list with all locks on this certificate. Attention: This list can also include locks, if this certificate cannot be removed automatically from the certificate store.

Returns:

The list with all locks on this certificate within the context of the certificate store this certificate container belongs to.

getInfoStructure

public CertificateInfoStructure getInfoStructure()

Creates an information structure with the settings stored within this certificate container. This structure can also be used outside the certificate store (while this container should not be used outside the certificate store because of the possibility of changing the settings to inconsistent states). The created structure can be used by an application to display the settings of the certificate. But if some of the settings shall be changed, it is necessary to call the corresponding method of the CertificateStore (if available).

Returns:

An information structure with the settings stored within this certificate container.

toXmlElement

public org.w3c.dom.Element toXmlElement(org.w3c.dom.Document a_doc)

Creates an XML node with most of the settings stored within this certificate container. This node can be used later again to construct a new instance of CertificateContainer.

Specified by:

toXmlElement in interface IXMLEncodable

Parameters:

a_doc - The XML document, which is the environment for the created XML node.

Returns:

The XML node with the settings stored within this certificate container ('CertificateContainer' node).

equals

public boolean equals(java.lang.Object a_certificateContainer)

Note: Only checks if the certificate in the container is the same

Overrides:

equals in class java.lang.Object

See Also:

JAPCertificate.equals()

getId

public java.lang.String getId()

Returns a unique id for this CertificateContainer. The Container has the same id as the included certifacte

Returns:

a unique id for this CertificateContainer

See Also:

JAPCertificate.getId()

hashCode

public int hashCode()

The hash code is derived from the certificate`s id.

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code of the certificate

See Also:

JAPCertificate.hashCode()
