Constructor Details

DefaultPDFBoxSignatureInterface

public DefaultPDFBoxSignatureInterface(PrivateKey privateKey,
 List<X509Certificate> certificates,
 String algorithm,
 AdesProfileType pades)

Constructor.

Parameters:

privateKey - private signing key

certificates - signing certificate chain

algorithm - signing algorithm

pades - PAdES type (may be null)

Method Details

getCmsSignedData

public byte[] getCmsSignedData()

Gets the result of the signing process in the form of ContentInfo holding SignedData.

Specified by:

getCmsSignedData in interface PDFBoxSignatureInterface

Returns:

the CMS ContentInfo holding SignedData

getCmsSignedAttributes

public byte[] getCmsSignedAttributes()

Gets the signed attributes from the result of the signing process.

Specified by:

getCmsSignedAttributes in interface PDFBoxSignatureInterface

Returns:

the CMS SignedAttributes

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()

Tells whether the signature should be generated according to the PAdES requirement profile.

Specified by:

isPades in interface PDFBoxSignatureInterface

Returns:

true if the signature is created as a PAdES compliant signature
