Constructor Detail

• SignerInfoGeneratorBuilder

  public SignerInfoGeneratorBuilder​(DigestCalculatorProvider digestProvider)

  Base constructor.

  Parameters:

  digestProvider - a provider of digest calculators for the algorithms required in the signature and attribute calculations.

• SignerInfoGeneratorBuilder

  public SignerInfoGeneratorBuilder​(DigestCalculatorProvider digestProvider,
                                    CMSSignatureEncryptionAlgorithmFinder sigEncAlgFinder)

  Base constructor with a particular finder for signature algorithms.

  Parameters:

  digestProvider - a provider of digest calculators for the algorithms required in the signature and attribute calculations.

  sigEncAlgFinder - finder for algorithm IDs to store for the signature encryption/signature algorithm field.

Method Detail

• setDirectSignature

  public SignerInfoGeneratorBuilder setDirectSignature​(boolean hasNoSignedAttributes)

  If the passed in flag is true, the signer signature will be based on the data, not a collection of signed attributes, and no signed attributes will be included.

  Returns:

  the builder object

• setSignedAttributeGenerator

  public SignerInfoGeneratorBuilder setSignedAttributeGenerator​(CMSAttributeTableGenerator signedGen)

  Provide a custom signed attribute generator.

  Parameters:

  signedGen - a generator of signed attributes.

  Returns:

  the builder object

• setUnsignedAttributeGenerator

  public SignerInfoGeneratorBuilder setUnsignedAttributeGenerator​(CMSAttributeTableGenerator unsignedGen)

  Provide a generator of unsigned attributes.

  Parameters:

  unsignedGen - a generator for signed attributes.

  Returns:

  the builder object

• build

  public SignerInfoGenerator build​(ContentSigner contentSigner,
                                   X509CertificateHolder certHolder)
                            throws OperatorCreationException

  Build a generator with the passed in certHolder issuer and serial number as the signerIdentifier.

  Parameters:

  contentSigner - operator for generating the final signature in the SignerInfo with.

  certHolder - carrier for the X.509 certificate related to the contentSigner.

  Returns:

  a SignerInfoGenerator

  Throws:

  OperatorCreationException - if the generator cannot be built.

• build

  public SignerInfoGenerator build​(ContentSigner contentSigner,
                                   byte[] subjectKeyIdentifier)
                            throws OperatorCreationException

  Build a generator with the passed in subjectKeyIdentifier as the signerIdentifier. If used you should try to follow the calculation described in RFC 5280 section 4.2.1.2.

  Parameters:

  contentSigner - operator for generating the final signature in the SignerInfo with.

  subjectKeyIdentifier - key identifier to identify the public key for verifying the signature.

  Returns:

  a SignerInfoGenerator

  Throws:

  OperatorCreationException - if the generator cannot be built.
