Hi mailing-list readers, i have read the archives but could not find an answer to this question:
In the PDF-Reference Third Edition version 1.4, First printing December 2001 on page 73, Section 3.5 "General Encryption Algorithm" can be found the following note: RC4 is a copyrighted, proprietary algorithm of RSA Security, inc. Adobe Systems has licensed this algorithm for use in its Acrobat products. Independant software vendors may be required to license RC4 in order to develop software that encrypts or decrypts PDF documents. I would like to password protect existing PDF-Forms using itext + RC4, as RC4 works with older versions of Acrobat. I alraedy know how to do that, but reading that note in the PDF-Reference book makes me wondering if i need a licence in order to do that? Any comments welcome-. Martin -- Psssst!
