Tobias, when there now is a discussion on removing that code, a likely outcome is that it actually is moved into some optional package. That way it wont be the first kind of signature anyone new to PDF signing tries but it will be still available for people whose requirements force them to sign that way.
Concerning your worries about PDF/A signing... actually using adbe.pkcs7.* is *recommended* for signing PDF/A, e.g. by the PDF/A Competence Center in their tech note 0006.

That conclusion is not correct: the PDF specification 1.4 of the Signature dictionary explicitly mentions certain signature handlers merely as examples, not as a finalized enumeration, and other entries don't even have such samples. Actually the /Cert key is not in the table of signature dictionary entries. Thus, one could argue that adbe.x509.rsa_sha1 may not be used for PDF/A signing as such signatures require the /Cert entry while adbe.pkcs7.* is perfectly ok. ;) Regards, Michael. -- View this message in context: http://itext-general.2136553.n4.nabble.com/Digital-signature-with-DSA-key-tp3264088p3276053.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
