Package se.swedenconnect.sigval.pdf.timestamp.issue.impl

Class DefaultPDFDocTimestampSignatureInterface

java.lang.Object

se.swedenconnect.sigval.pdf.timestamp.issue.impl.DefaultPDFDocTimestampSignatureInterface

All Implemented Interfaces:

org.apache.pdfbox.pdmodel.interactive.digitalsignature.SignatureInterface, se.idsec.signservice.security.sign.pdf.PDFBoxSignatureInterface, PDFDocTimestampSignatureInterface

public class DefaultPDFDocTimestampSignatureInterface
extends Object
implements PDFDocTimestampSignatureInterface

Implementation of the PDF box signing interface used to add a document timestamp to a PDF document which includes a SVT token. This implementation generates the timestamp as part of this service. Another implementation of this interface could allow an external time stamp service to provide the timestamp.

DefaultPDFDocTimestampSignatureInterface

public DefaultPDFDocTimestampSignatureInterface(PrivateKey privateKey,
 List<X509Certificate> certificates,
 String algorithm)

Constructor.

Parameters:

privateKey - private signing key

certificates - signing certificate chain

algorithm - signing algorithm

Method Details

getCmsSignedData

public byte[] getCmsSignedData()

Specified by:

getCmsSignedData in interface se.idsec.signservice.security.sign.pdf.PDFBoxSignatureInterface

getCmsSignedAttributes

public byte[] getCmsSignedAttributes()

Specified by:

getCmsSignedAttributes in interface se.idsec.signservice.security.sign.pdf.PDFBoxSignatureInterface

getCertificateChain

public List<X509Certificate> getCertificateChain()

Specified by:

getCertificateChain in interface PDFDocTimestampSignatureInterface

setSvt

public void setSvt(String svt)

Specified by:

setSvt in interface PDFDocTimestampSignatureInterface

getSvt

public String getSvt()

Specified by:

getSvt in interface PDFDocTimestampSignatureInterface

sign

public byte[] sign(InputStream content)
            throws IOException

SignatureInterface implementation.

This method will be called from inside of the pdfbox and creates the PKCS #7 signature (CMS ContentInfo). The given InputStream contains the bytes that are given by the byte range.

Specified by:

sign in interface org.apache.pdfbox.pdmodel.interactive.digitalsignature.SignatureInterface

Parameters:

content - the message bytes being signed (specified by ByteRange in the signature dictionary)

Returns:

CMS ContentInfo bytes holding the complete PKCS#7 signature structure

Throws:

IOException - error during signature creation

isPades

public boolean isPades()

Specified by:

isPades in interface se.idsec.signservice.security.sign.pdf.PDFBoxSignatureInterface
