All Implemented Interfaces:

Serializable, LiteralPolicyExpression<Collection<String>>, PolicyExpression, ReferencePolicyExpression<X509Certificate,Collection<String>>, ExtensionField<Collection<String>>, TBSField<Collection<String>>, X509Field<Collection<String>>

public class SubjectAltNameExtensionField
extends AbstractExtensionField<Collection<String>>
implements ExtensionField<Collection<String>>

Subject alternative name extension field.

The policy value of this extension is returned as a collection of strings containing a concatenation of the name type and the actual name. For example, an alt name of rfc822 would look like the following.

   rfc822:gm2552@direct.securehealthemail.com
 

If the extension does not exist in the certificate, then the policy value returned by this class evaluates to an empty collection.

Constructor Detail

SubjectAltNameExtensionField

public SubjectAltNameExtensionField(boolean required)

Constructor

Parameters:

required - Indicates if the field is required to be present in the certificate to be compliant with the policy.

Method Detail

injectReferenceValue

public void injectReferenceValue(X509Certificate value)
                          throws PolicyProcessException

Injects the referenced value into the expressions. The relevant accessible attribute of the reference object can be retrieved by calling the LiteralPolicyExpression.getPolicyValue() method.

Specified by:

injectReferenceValue in interface ReferencePolicyExpression<X509Certificate,Collection<String>>

Parameters:

value - The reference value.

Throws:

PolicyProcessException - Thrown if the reference value cannot be successfully processed or the relevant accessible attribute cannot be retrieved from the value. For example, the X509 reference expressions may require an X509 attribute to be present in a certificate. If the required certificate attribute is not present, the this exception would be thrown.

getExtentionIdentifier

public ExtensionIdentifier getExtentionIdentifier()

Gets the object identifier for the extension field.

Specified by:

getExtentionIdentifier in interface ExtensionField<Collection<String>>

Returns:

The object identifier for the extension field.
