public class CMSSignedDataStreamGenerator
extends CMSSignedGenerator

General class for generating a pkcs7-signature message stream.

A simple example of usage.

X509Certificate signCert = ... certList.add(signCert); Store certs = new JcaCertStore(certList); ContentSigner sha1Signer = new JcaContentSignerBuilder("SHA1withRSA").setProvider("BC").build(signKP.getPrivate()); CMSSignedDataStreamGenerator gen = new CMSSignedDataStreamGenerator(); gen.addSignerInfoGenerator( new JcaSignerInfoGeneratorBuilder( new JcaDigestCalculatorProviderBuilder().setProvider("BC").build()) .build(sha1Signer, signCert)); gen.addCertificates(certs); OutputStream sigOut = gen.open(bOut); sigOut.write("Hello World!".getBytes()); sigOut.close();

Method Summary
 java.io.OutputStream open(org.bouncycastle.asn1.ASN1ObjectIdentifier eContentType, java.io.OutputStream out, boolean encapsulate)
          generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature.
 java.io.OutputStream open(org.bouncycastle.asn1.ASN1ObjectIdentifier eContentType, java.io.OutputStream out, boolean encapsulate, java.io.OutputStream dataOutputStream)
          generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature.
 java.io.OutputStream open(java.io.OutputStream out)
          generate a signed object that for a CMS Signed Data object using the given provider.
 java.io.OutputStream open(java.io.OutputStream out, boolean encapsulate)
          generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature with the default content type "data".
 java.io.OutputStream open(java.io.OutputStream out, boolean encapsulate, java.io.OutputStream dataOutputStream)
          generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature with the default content type "data".

public CMSSignedDataStreamGenerator()
base constructor
Method Detail

setBufferSize

public void setBufferSize(int bufferSize)
Set the underlying string size for encapsulated data
Parameters:
bufferSize - length of octet strings to buffer the data.

open

public java.io.OutputStream open(java.io.OutputStream out)
                          throws java.io.IOException
generate a signed object that for a CMS Signed Data object using the given provider.

open

public java.io.OutputStream open(java.io.OutputStream out,
                                 boolean encapsulate)
                          throws java.io.IOException
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature with the default content type "data".

open

public java.io.OutputStream open(java.io.OutputStream out,
                                 boolean encapsulate,
                                 java.io.OutputStream dataOutputStream)
                          throws java.io.IOException
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature with the default content type "data". If dataOutputStream is non null the data being signed will be written to the stream as it is processed.
Parameters:
out - stream the CMS object is to be written to.
encapsulate - true if data should be encapsulated.
dataOutputStream - output stream to copy the data being signed to.

open

public java.io.OutputStream open(org.bouncycastle.asn1.ASN1ObjectIdentifier eContentType,
                                 java.io.OutputStream out,
                                 boolean encapsulate)
                          throws java.io.IOException
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature. The content type is set according to the OID represented by the string signedContentType.

open

public java.io.OutputStream open(org.bouncycastle.asn1.ASN1ObjectIdentifier eContentType,
                                 java.io.OutputStream out,
                                 boolean encapsulate,
                                 java.io.OutputStream dataOutputStream)
                          throws java.io.IOException
generate a signed object that for a CMS Signed Data object using the given provider - if encapsulate is true a copy of the message will be included in the signature. The content type is set according to the OID represented by the string signedContentType.
Parameters:
eContentType - OID for data to be signed.
out - stream the CMS object is to be written to.
encapsulate - true if data should be encapsulated.
dataOutputStream - output stream to copy the data being signed to.
