I have signed PDF document. I have to get its signature bytes - not to verify
the signature. How can I do that - I' ve tried the following :
try{
PdfReader reader = new PdfReader(signedDocBytes);
AcroFields af = reader.getAcroFields();
ArrayList names = af.getSignatureNames();
for (Object name1 : names) {
String name = (String) name1;
PdfPKCS7 pk = af.verifySignature(name);
byte[] ssig = pk.getEncodedPKCS7();
System.out.println("TEST : " + ssig);
}
} catch (IOException e) {
Auxilary.logException(e);
}
but an exception have been thrown : SignatureException: object not initialized
for signing.
Thanks in advance :)
