Constructor Details

CadesSignature

public CadesSignature(CadesSignatureContainer cadesSignatureContainer,
org.bouncycastle.cms.SignerInformation signerInformation,
CmsParent<CadesSignature> parent)

Cria uma assinatura CAdES

Parameters:

cadesSignatureContainer - Contêiner ao qual a assinatura está inserida

signerInformation - O SignerInformation do assinante ao qual se deseja obter a assinatura.

parent - Representação do "pai" da assinatura que deseja ser obtida.

Method Details

setTimeReference

public void setTimeReference(Date timeReference)

getTimeReference

public Date getTimeReference()

isCounterSignature

public boolean isCounterSignature()

getEContentType

public String getEContentType()

Returns:

O valor do atributo eContentType.

getCadesSignatureContainer

public CadesSignatureContainer getCadesSignatureContainer()

Returns:

O contêiner ao qual a assinatura pertence.

addCounterSignature

public void addCounterSignature(IdCounterSignature counterSignatureAttribute)

Adiciona uma contra-assinatura.

Overrides:

addCounterSignature in class CadesSignatureInformation

Parameters:

counterSignatureAttribute - O atributo da contra-assinatura.

replaceCounterSignature

public void replaceCounterSignature(IdCounterSignature counterSignatureAttribute)

Esse método deve ser usado quando uma contra-assinatura sofre alguma alteração (por exemplo: adição de um novo atributo não assinado). Assim, a assinatura que contém a contra assinatura deverá utilizar este método.

Parameters:

counterSignatureAttribute - A contra-assinatura a ser atualizada

getAttributeCertificatesFromSignedData

public List<org.bouncycastle.cert.X509AttributeCertificateHolder> getAttributeCertificatesFromSignedData()

Obtém os certificados de atributos da assinatura.

Returns:

Lista de certificados de atributos da assinatura.

getCertificatesFromSignedData

public List<X509Certificate> getCertificatesFromSignedData()
                                                    throws CertificateException

Returns:

Os certificados da assinatura

Throws:

CertificateException

getCRLsFromSignedData

public List<X509CRL> getCRLsFromSignedData()
                                    throws CRLException

Returns:

As CRLs da assinatura

Throws:

CRLException - Exceção em caso de erro na manipulação das CRLs

getDigestAlgorithm

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getDigestAlgorithm()

Obtém o identificador do algoritmo de digestão da assinatura.

Returns:

O identificador do algoritmo de digestão.
