public class NoCheck

extends V3Extension

This class implements the OCSP NoCheck extension.

Each OCSP extension is associated with a specific ocsp extension object identifier, derived from RFC 2560:

 id-pkix  OBJECT IDENTIFIER  ::=
        { iso(1) identified-organization(3) dod(6) internet(1)
          security(5) mechanisms(5) pkix(7) }

 id-ad OBJECT IDENTIFIER ::= { id-pkix 48 }       
        -- arc for access descriptors

 id-ad-ocsp      OBJECT IDENTIFIER ::= { id-ad 1 }
 
 id-pkix-ocsp    OBJECT IDENTIFIER ::= { id-ad-ocsp }
 

The object identifier for the NoCheck extension is defined as:

 id-pkix-ocsp-nocheck    OBJECT IDENTIFIER ::= { id-pkix-ocsp 5 }
 

which corresponds to the OID string "1.3.6.1.5.5.7.48.1.5".

The Online Certificate Status Protocol (RFC 2560) specifies the NoCheck extension for being included in certificates when CA may specify that an OCSP client can trust a responder for the lifetime of the responder's certificate. CAs issuing such a certificate should realized that a compromise of the responder's key, is as serious as the compromise of a CA key used to sign CRLs, at least for the validity period of this certificate. CA's may choose to issue this type of certificate with a very short lifetime and renew it frequently.

ASN.1 definition:

 NoCheck ::= NULL
 

 For adding a NoCheck extension object to 
 a X509Certificate, use the addExtension method of the 
 iaik.x509.X509Certificate
 class, e.g.:
 
 NoCheck noCheck = new NoCheck();
 cert.addExtension(noCheck);

Field Detail



oid
public static final ObjectID oid

The object identifier of this NoCheck extension. 
 The corresponding OID string is "1.3.6.1.5.5.7.48.1.5".




Constructor Detail



NoCheck
public NoCheck()

Creates a NoCheck object.




Method Detail



getObjectID
public ObjectID getObjectID()

Returns the object ID of this NoCheck extension

Overrides:
getObjectID in class V3Extension


Returns:
the object ID





init
public void init(ASN1Object obj)

Inits this NoCheck implementation with an ASN1object
 representing the value of this extension.
 

 The given ASN1Object is the one created by toASN1Object().
 

 This method is used by the X509Extensions class when parsing the ASN.1 representation
 of a OCSP object for properly initializing an included
 NoCheck 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.
 

 The ASN1Object supplied to this method will reflect the
 ASN.1 representation of the NoCheck extension value:
 
 NoCheck ::= NULL
 

Overrides:
init in class V3Extension


Parameters:
obj - the NoCheck as ASN1Object (NULL)





toASN1Object
public ASN1Object toASN1Object()

Returns an ASN1Object representing the value of this 
 NoCheck extension.
 

 The ASN1Object returned by this method will reflect the
 ASN.1 representation of the NoCheck extension value:
 
 NoCheck ::= NULL
 

Overrides:
toASN1Object in class V3Extension


Returns:
the value of this NoCheck as ASN1Object (NULL)





hashCode
public int hashCode()

Returns a hashcode for this identity.

Overrides:
hashCode in class V3Extension


Returns:
a hash code for this identity





toString
public String toString()

Returns a string that represents the contents of this
 NoCheck extension.

Overrides:
toString in class Object


Returns:
the string representation
