Hi Javadoc, are yu really going in the right direction ? I would presume the rangestream the most important part when it comes to signing PDFs. We process most part of the signature outside iText in a different crypto provider, but praise the lord every day for the availability of the rangestream !
What's your use case ? Greetings Andreas ----- Original Message ---- From: Javadoc <[email protected]> To: [email protected] Sent: Tue, December 1, 2009 3:12:26 AM Subject: [iText-questions] Signing from hash, not rangestream. I've been modifying the standard itext example of signing with an external signature. Normally you use the Signature.update(byte[]) method to input the range stream into to the signature object and then call Signature.sign() to return the digest. I would like to use a MessageDigest to return the PDF's hash and then sign the hash against my certificate/key like normal. Does anyone have any good ideas to get me pointed in the right direction? Thanks!
