Class ValidityAssuredShortTermCerts

java.lang.Object

iaik.x509.V3Extension

iaik.x509.extensions.etsi.ValidityAssuredShortTermCerts

public class ValidityAssuredShortTermCerts
extends V3Extension

This class implements the ValidityAssuredShortTermCerts Extension specified by ETSI EN 319 412-1.

The ValidityAssuredShortTermCerts certificate extension indicates that the validity of the certificate is assured (and therefore may not have to be checked) because it is a short-term certificate; see ETSI EN 319 412-1 V1.4.4 (2021-05).

The object identifier for the ValidityAssuredShortTermCerts extension is specified as (see ETSI EN 319 412-1 V1.4.4):

 id-etsi-ext OBJECT IDENTIFIER ::= { itu-t(0) identified-organization(4) etsi(0)
                                  id-cert-profile(194121) 2 }
 -- Extension for short-term certificate
   id-etsi-ext-valassured-ST-certs OBJECT IDENTIFIER ::= { id-etsi-ext 1 }
 

which corresponds to the OID string "0.4.0.194121.2.1".

The ASN.1 definition of the ValidityAssuredShortTermCerts extension is specified as follows:

 ext-etsi-valassured-ST-certs EXTENSION ::= { SYNTAX NULL IDENTIFIED BY
                                          id-etsi-ext-valassured-ST-certs }
 

Since the ValidityAssuredShortTermCerts extension has no specific value (only is presence in a certificate is sufficient to indicate that the validity of the certificate is assured) a ValidityAssuredShortTermCerts extension can be created by simply calling the default constructor:

 X509Certificate certificate = new X509Certificate();
  ...
 ValidityAssuredShortTermCerts validityAssuredShortTermCertsExt = new ValidityAssuredShortTermCerts();
 certificate.addExtension(validityAssuredShortTermCertsExt);
 

Use method getExtension for getting a ValidityAssuredShortTermCerts extension when parsing a certificate:

 X509Certificate cert = ...;
 ...
 // look if ValidityAssuredShortTermCerts extension is included:
 ValidityAssuredShortTermCerts serviceProvider = cert.getExtension(ValidityAssuredShortTermCerts.oid);
 if (serviceProvider != null) {
   ...
 }

Field Detail

oid

public static final ObjectID oid

The object identifier of this ValidityAssuredShortTermCerts extension. The corresponding OID string is "0.4.0.194121.2.1".

Constructor Detail

ValidityAssuredShortTermCerts

public ValidityAssuredShortTermCerts()

Creates a new ValidityAssuredShortTermCerts extension.

Method Detail

getObjectID

public ObjectID getObjectID()

Returns the object ID of this ValidityAssuredShortTermCerts extension.

Specified by:

getObjectID in class V3Extension

Returns:

The object ID ("0.4.0.194121.2.1") of this extension.

init

public void init(ASN1Object asn1Object)
          throws X509ExtensionException

Inits this ValidityAssuredShortTermCerts implementation with an ASN1Object representing the value of this extension.

The given ASN1Object may be the one created by toASN1Object().

This method is used by the X509Extensions class when parsing the ASN.1 representation of a certificate for properly initializing an included ValidityAssuredShortTermCerts extension. This method initializes the extension only with its value, but not with its critical specification. For that reason, this method shall not be explicitly called by an application.

Specified by:

init in class V3Extension

Parameters:

asn1Object - The ValidityAssuredShortTermCerts extension value as ASN1Object (NULL).

Throws:

X509ExtensionException - If the extension value is not an ASN.1 NULL object

toASN1Object

public ASN1Object toASN1Object()

Returns an ASN1Object representing the value of this ValidityAssuredShortTermCerts extension object.

The returned ASN1Object is either an ASN.1 NULL object:

 ValidityAssuredShortTermCerts ::= NULL
 

Specified by:

toASN1Object in class V3Extension

Returns:

The value of this ValidityAssuredShortTermCerts as ASN1Object (NULL).

hashCode

public int hashCode()

Returns a hashcode for this identity.

Specified by:

hashCode in class V3Extension

Returns:

A hash code for this identity

equals

public boolean equals(java.lang.Object otherObject)

Compares this object with the given one..

Overrides:

equals in class java.lang.Object

Parameters:

otherObject - The other object to compare with.

Returns:

true, if this object is equal to the other object, false otherwise.

toString

public java.lang.String toString()

Returns a string that represents the contents of this extension. Since the ValidityAssuredShortTermCerts does not have a value, this method in any case returns an empty String ("").

Overrides:

toString in class java.lang.Object

Returns:

The string representation of this object.
