This is an example for singing a pdf with bouncy castle.

A keystore can be created with the java keytool (e.g. keytool -genkeypair -storepass 123456 -storetype pkcs12 -alias test -validity 365 -v -keyalg RSA -keystore keystore.p12 )

Constructor Detail

CreateSignature

public CreateSignature(KeyStore keystore,
                       char[] pin)

Initialize the signature creator with a keystore (pkcs12) and pin that should be used for the signature.

Parameters:

keystore - is a pkcs12 keystore.

pin - is the pin for the keystore / private key

Method Detail

signPDF

public File signPDF(File document)
             throws IOException,
                    org.apache.pdfbox.exceptions.COSVisitorException,
                    org.apache.pdfbox.exceptions.SignatureException

Signs the given pdf file.

Parameters:

document - is the pdf document

Returns:

the signed pdf document

Throws:

IOException

org.apache.pdfbox.exceptions.COSVisitorException

org.apache.pdfbox.exceptions.SignatureException

sign

public byte[] sign(InputStream content)
            throws org.apache.pdfbox.exceptions.SignatureException,
                   IOException

SignatureInterface implementation.

This method will be called from inside of the pdfbox and create the pkcs7 signature. The given InputStream contains the bytes that are providen by the byte range.

This method is for internal use only.

Here the user should use his favorite cryptographic library and implement a pkcs7 signature creation.
