QUESTION
I am trying to sign a pdf document from a 3rd party signature provider. I send them the document hash, after creating the empty signature and they send a timestamp token (we agreed it would be a timestamp signature) and I add the signature back into the pdf. the api call to get the timestmp and crl and ocsp goes well, but once I generate the pdf with the signature, adobe says the signature is not valid and the error is:
Error during signature verification.
Signature contains incorrect, unrecognized, corrupted or suspicious data. Support Information: SigDict /Contents illegal data
this is the current code:
signatureprovider.java

QUESTION
I have created code with iText 7 that is able to digitally sign a given PDF with a X509 certificate that uses an ECDSA key pair. When I open this signed PDF in Acrobat Reader DC, it correctly reads it, and verifies it to be valid (meaing doc is unmodified since signing, etc etc).
However, when I try to validate this same document with iText 7, the integrity and authenticity check returns false.
Here is a sample code:
...ANSWER
Answered 2021-Apr-25 at 16:00There is an issue in your ECDSA signatures which is only ignored by Adobe Acrobat but not by iText 7.
There are two major formats to encode an ECDSA signature value:
as a TLV

QUESTION
I would like to update Table Lease from Table History
...ANSWER
Answered 2021-Feb-07 at 01:19Your Lease table has a serious design problem, because it is storing users as a CSV list. Instead, you should have each user value on a separate record. That being said, it appears that the CSV user list is immaterial to your current problem, which only required finding the earliest date for each lease. If so, then a simple update join should suffice:

I want to fetch data from the Internet, so I use a function named getNumData and placed it in the Build function. The getNumData function uses http.get to fetch data, and then store it after decoded. Here comes the problem. I have to call setState to store the data (set the Numdata List to the data I just fetched). But if I do so, it becomes a "setState called during Build" error. This is kind of an awkward situation. What can I do to reslove the problem? Thanks for instance.

im trying to sign a document several times simulating a signature by different users using itext 5.5.13.1, PdfStamper is on AppendMode. If document has not signatures, the certification level is CERTIFIED_NO_CHANGES_ALLOWED or CERTIFIED_FORM_FILLING_AND_ANNOTATIONS, else i dont set this param for PdfSignatureAppearence. After the second signing the first signature is invalid, because the document was changed. Any ideas how to fix this? Here's my code:
...ANSWER
Answered 2020-Jun-17 at 08:58The most important part of your screenshot
is the text "1 Page(s) Modified" between the signatures on the signature panel. This tells us that you do other changes than merely adding and filling signature fields. Inspecting the file itself one quickly recognizes the change:
In the original sample.pdf
there is just a single content stream.
In sample_signed.pdf with one signature
there are three content streams, the original one enveloped by the new ones.
In sample_signed_signed.pdf with two signatures
there are five content streams, the former three enveloped by two new ones.
So in each signing pass you change the page content. As you can read in this answer, changes to the page content of signed documents are always disallowed. It doesn't even help that the contents of the added streams are trivial, each stream added in front contains:

TextInput is a component. I want to set a current Date for the part with formKey = {'signDate'} using the TextInput component.
I have shared the use of component below.
If conditionally formKey = {'signDate'},
I want to send a current Date to the changeSelected method.
If the key is not 'signDate', it should set the input value.
How can I do that?

QUESTION
I am trying to add multiple signatures with iTextSharp 5.5.13.1.
Only the last signature is valid.
And all previous signatures are invalid with the message:
"Document has been altered or corrupted since it was signed" - 1 Page(s) Modified
I don't necessarily need certified signatures.
I use signature append mode but still can't figure out what modifies the document.
In notepad the first part of document till the second signature seems unchanged.
The code I used is:
...ANSWER
Answered 2020-May-16 at 10:41Your code as is adds an image to the static content of a page. That is forbidden to do to a signed file. For details on allowed and disallowed changes to a signed PDF read this answer.
According to your code comments, though, you also tried to alternatively add the image to the signature appearance. That is not forbidden as such. But analyzing the provided example PDFs it becomes apparent that in this attempt additional content streams have been added to the page. Even though they essentially are empty, this is considered a change of page content which is disallowed.
As it turned out, you didn't add the image to the page content in this attempt but you still retrieved the OverContent of the page:
