It didn't help. I used filter PdfName.ADBE_PKCS7_SHA1 and set hasRsaData
to true.
PdfPKCS7 pk7 = new PdfPKCS7(null, chain, null, "SHA1", true);
pk7.SetExternalDigest(digest, rsadata, "RSA");
reader's signature panel says that an error ocecured while attempting to
validate this signature.

The final parameter of the constructor, the boolean hasRSAdata, is
documented in the method Javadoc as "true if the sub-filter is
adbe.pkcs7.sha1". Isn't that your sub-filter of choice? Could that "false"
I followed Acrobat's document "Signing and the Byte Range" :
1) I hash PDF ByteStream data using SHA1
2) this hash is being encrypted using SmartCard internals (mechanism
SHA1_RSA)
"The hash value is encrypted with the signer’s private key using a
supported RSA or DSA signature algorithm. A signat

A good starting point would be studying the PDF Ref (ISO32000-1:2008)
chapter 12.8.3.3 "PKCS#7 Signatures as used in ISO 32000" and additionally

If filter is adobe.PKCS7.sha1 and I would like to create hashed
siganture then how to achieve it ?
If you take a look on my posted code and correct me if it is correct to
call sap.SetExternalDigest twice ?
And what about SetExternalDigest function paramers ?
1) Digest is signed hash, correct ?

I created external digest using SetExternalDigest. But for some reason
PDF says "An error occured while attempting to validate this signature".
Here is what I do:
1) I calculate SHA1 hash from the PDF content (digest variable)
2) this hash is signed on the SmartCard and returned as rsadata

Hi,
Does iText/iTextSharp allow creating PdfPKCS7 object when private key is
not accessible ? (singing operation is done on the SmartCard). All I
have is
1) a hash generated from the PDF content
2) X509 certificate
3) encrypted hash value
If not, then do I have to write all PKCS7 releted from th
