Is it possible to digitally sign a PDF using iTextSharp 4.1.6.0? If so, is there some example documentation in C#?
推荐答案
是的,可以使用该版本进行签名.关于如何签名的描述-互联网档案是您的
Yes it is possible to sign with that version. There was a description on how to sign - the internet archive is your friend.
并且请注意iText人士的评论,它是一个过时的版本-今天有更新的标准,例如PAdES等.
And please note the comments of the iText folks that this is an outdated version - today there are newer standards like PAdES etc.
(但是,我不同意Bruno的类比:问题不是我可以在黑白电视上观看彩色电视吗?"
但是"我仍然可以在B& B上观看电视吗?W电视?"
当然可以,在b& w中.为什么现在要坚持使用b& w电视,这是鱼缸不一样的问题.)
(I however disagree with Bruno's analogy: The question is not "Can I watch color TV on my b&w television?"
BUT "Can I still watch TV on a B&W television?"
Sure you can, in b&w. The question of why you'd stick with a b&w TV nowadays that's a different kettle of fish.)
