All Implemented Interfaces:

CounterSignatureInterface, CmsParent<CadesSignature>, GenericCadesSignature, Signature<org.bouncycastle.asn1.cms.Attribute>, SignatureAttribute<org.bouncycastle.asn1.cms.Attribute>, SignatureObject

public class IdCounterSignature
extends CadesSignature
implements CounterSignatureInterface

Representa uma contra assinatura no formato CAdES.

Oid e esquema do atributo id-countersignature retirado da RFC 3852:

  id-countersignature OBJECT IDENTIFIER ::= { iso(1) member-body(2)
  us(840) rsadsi(113549) pkcs(1) pkcs9(9) 6 }

  Countersignature ::= SignerInfo

Field Details

IDENTIFIER

public static final String IDENTIFIER

Constructor Details

IdCounterSignature

public IdCounterSignature(AbstractVerifier signatureVerifier,
Integer index)

Esse construtor é utilizado para a verificação da contra assinatura.

Parameters:

signatureVerifier - Usado para criar e verificar o atributo

index - Índice usado para selecionar o atributo

IdCounterSignature

public IdCounterSignature(org.bouncycastle.cms.SignerInformation counterSigner,
CmsParent<CadesSignature> parent)

Esse construtor é utilizado para a assinatura da contra assinatura.
Chama o construtor da super classe passando o contra assinante, e passa true como argumento, pois toda contra assinatura deve ser detached.

Parameters:

counterSigner - SignerInformation do contra-assinante

parent - A assinatura que será contra assinada

Method Details

getIthCounterSignature

public static org.bouncycastle.cms.SignerInformation getIthCounterSignature(CadesSignature signature,
int n)

getEncoded

public org.bouncycastle.asn1.cms.Attribute getEncoded()
                                               throws SignatureAttributeException

Description copied from interface: SignatureAttribute

Retorna o atributo codificado

Specified by:

getEncoded in interface SignatureAttribute<org.bouncycastle.asn1.cms.Attribute>

Returns:

O atributo no formato em que foi parametrizado a classe

Throws:

SignatureAttributeException

getIdentifier

public String getIdentifier()

Description copied from interface: SignatureAttribute

Retorna o identificador do atributo

Specified by:

getIdentifier in interface SignatureAttribute<org.bouncycastle.asn1.cms.Attribute>

Returns:

O identificador do atributo

isSigned

public boolean isSigned()

Description copied from interface: SignatureAttribute

Informa se o atributo é assinado.

Specified by:

isSigned in interface SignatureAttribute<org.bouncycastle.asn1.cms.Attribute>

Returns:

Indica se o atributo é assinado

validate

public void validate()
              throws SignatureAttributeException

Método não utilizado por esta classe, pois a validade da contra assinatura é realizada através da classe SignatureVerifier

Specified by:

validate in interface SignatureAttribute<org.bouncycastle.asn1.cms.Attribute>

Throws:

SignatureAttributeException

isUnique

public boolean isUnique()

Description copied from interface: SignatureAttribute

Verifica se o atributo deve ter apenas uma instância na assinatura

Specified by:

isUnique in interface SignatureAttribute<org.bouncycastle.asn1.cms.Attribute>

Returns:

Indica se o atributo deve ter apenas uma instância na assinatura
