public class AlgorithmIdentifier

extends DERSequencePr

AlgorithmIdentifier class is DER encoded Algorithm identifier represented in ASN.1 notation according to RFC2630.

AlgorithmIdentifier ::= SEQUENCE {

algorithm AlgorithmIdentifier,

parameters ANY DEFINED BY algorithm OPTIONAL }

AlgorithmIdentifier ::= OBJECT IDENTIFIER

Constructor Summary

AlgorithmIdentifier(int[] arrayID0)
Array of numbers is used for construction of DERObjectIdentifier.

AlgorithmIdentifier(java.lang.String id0, java.lang.String typeConstruction0)
This constructor has two different forms, depend on parameter typeConstruction0, which can be: DOT_SEPARATED_ARRAY or NAME_STRING.

Method Summary

void	addNullToAlgorithmId() Adds DERNull parameter to AlgorithmIdentifier
void	addParamToAlgorithmId(byte[] parameter0) Adds parameter to AlgorithmIdentifier

Constructor Detail

AlgorithmIdentifier

public AlgorithmIdentifier(java.lang.String id0,
                           java.lang.String typeConstruction0)
                    throws SMIMEException

This constructor has two different forms, depend on parameter typeConstruction0, which can be: DOT_SEPARATED_ARRAY or NAME_STRING. If typeConstruction0 parameter is DOT_SEPARATED_ARRAY then id0 definition is represented by numbers separated with dots (example: "1.2.840.113549.1.1.1"). In case of NAME_STRING, id0 definition is name of object identifier (example: "RSA").

Parameters:

id0 - defines Object Identifier in representation determined by second parameter - typeConstruction0.

typeConstruction0 - can take values DOT_SEPARATED_ARRAY and NAME_STRING

Throws:

SMIMEException - if wrong type of parameters are passed to the constructor. Also, it can be thrown from super class constructor or its addContent method.

AlgorithmIdentifier

public AlgorithmIdentifier(int[] arrayID0)
                    throws SMIMEException

Array of numbers is used for construction of DERObjectIdentifier. Every number in array represents one number between dots in object identifier string.

Parameters:

arrayID0 - array of defined numbers (example: for RSA algoriths, numbers are 1, 2, 840, 113549, 1, 1, and 1)

Throws:

SMIMEException - if wrong type of parameters are passed to the constructor. Also, it can be thrown from super class constructor or its addContent method.

Method Detail

addNullToAlgorithmId

public void addNullToAlgorithmId()
                          throws SMIMEException

Adds DERNull parameter to AlgorithmIdentifier

Throws:

SMIMEException - thrown from super class addContent method.

addParamToAlgorithmId

public void addParamToAlgorithmId(byte[] parameter0)
                           throws SMIMEException

Adds parameter to AlgorithmIdentifier

Parameters:

parameter0 - byte array representation of appropriate parameter

Throws:

SMIMEException - thrown from super class addContent method.
