public class EntrustVersInfo

extends V3Extension

This class implements the EntrustVersInfo Extension.

The EntrustVersInfo extension is used by Entrust Technologies to identify the version and other information about the CA which issued the certificate.

The EntrustVersInfo OID is "1.2.840.113533.7.65.0".

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

 EntrustVersInfo ::=  SEQUENCE {
     entrustVers	[0]  GeneralString,
     entrustInfo	[1]  BIT_STRING }
 

The entrustVers field specifies the version of Entrust/Manager that created the certificate. The entrustInfo field is a proprietary bitmap used to describe the certificate and the manner in which it was created.

This class provides several methods for getting (but not setting) the component values of a EntrustVersInfo extension object.

Returns the object ID of this EntrustVersInfo extension

Overrides:

getObjectID in class V3Extension

Returns:

the object ID

init

public void init(ASN1Object obj)
          throws X509ExtensionException

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

The ASN1Object is the extensionValue from ASN.1 type "Extension" representing the entrustVers and entrustInfo values of this extension.

Overrides:

init in class V3Extension

Parameters:

obj - the extensionValue as an ASN1Object

Throws:

toASN1Object

public ASN1Object toASN1Object()

Stub function to meet V3Extension criteria. Returns null.

Overrides:

toASN1Object in class V3Extension

Tags copied from class: V3Extension

Returns:

the value of the extension as ASN1Object

Throws:

X509ExtensionException - if the extension could not be created

getEntrustVers

public java.lang.String getEntrustVers()

Returns the entrustVers value of this EntrustVersInfo extension specifying the version of the Entrust/Manager which issued the certificate.

Returns:

the entrustVers value.

public byte getEntrustInfo()

Returns the entrustInfo value of this EntrustVersInfo extension specifying details about the certificate and how it was created.

Returns:

the entrustInfo value.

hashCode

public int hashCode()

Returns a hashcode for this identity.

Overrides:

hashCode in class V3Extension
