QUESTION
I want to digitally sign pdf documents using iText 7. The signature is created by an external service which returns a PKCS1 signature only. I then have to create and apply the PKCS7.
There is a good documentation for this scenario from iText: https://kb.itextpdf.com/home/it7kb/examples/how-to-use-a-digital-signing-service-dss-such-as-globalsign-with-itext-7
Sample applicationI have created a sample application which signs pdf documents via local certificate. This sample application can be cloned from https://github.com/suntsu42/PdfSignSamplePkcs1. In this sample application are two different ways of creating the PKCS7. Once manually and once via a IExternalSignature(PrivateKeySignature) implementation.
For both cases, the pdf digest which must be signed is created in the same way. The only difference is the way the PKCS7 is created.
The project on github (https://github.com/suntsu42/PdfSignSamplePkcs1) is complete and self contained. In the resources folder is a private key file (pfx) used for creating the signature as well as the root certificate. In order to run the example, it should be enough to just change the value of the resourcePath variable to accommodate your local system.
The signature creation can be toggled by changeing the value of createSignatureViaPlainPkcs1

In CreatePKCS7 you sign the to-be-signed attributes of the signature container (GetAuthenticatedAttributeBytes) which contain the document digest (Digest):

I am trying to set up some tests in angular. In order to make this easier I created some default json objects in separate json files that can be imported and used in the test.
see below for simple test
...ANSWER
Answered 2021-Feb-16 at 17:09JSON files are provided by your loader as synthetic modules with a single default export containing their parsed JSON as a JavaScript object. Therefore using the namespace import syntax, import * as m from "m.json", is unnecessary and the cause of the poor ergonomics you are experiencing. Simply fix your imports: import m from "m.json".

QUESTION
Im trying to create a C# Program that can Digitally Sign PDF Documents. For Including the Signature Element into the PDF I'm using iText7.
Now if I run the program without the debugger a System.NullReferenceException will be thrown and the program fails. But if I run the Program with the debugger the exception also occurs and the code continues and sign the PDF correctly...
Im not sure if this a problem of iText7 or if I made a mistake or forgot something important while creating the signature field.
Any Ideas how to solve this?

My Code
...ANSWER
Answered 2020-Jul-31 at 15:01In your code you don't set the signer certificate using PdfSignatureAppearance.SetCertificate. While iText indeed does not need a certificate for the actual signing process in case of a SignExternalContainer use case like yours, it does need it for retrieving information about the signer to use as name and in the description in case of visible signatures with name and/or descriptions (i.e. any rendering mode but pure GRAPHICS).
Your setting "RenderingMode": 1 and your stack trace PdfSignatureAppearance.cs:Zeile 584 indicate that you are in a NAME_AND_DESCRIPTION use case. Thus, iText attempts to build a description, accesses its signCertificate, and fails because that member is null.
To fix this, please also set the signer certificate using PdfSignatureAppearance.SetCertificate.
In case of DESCRIPTION and GRAPHIC_AND_DESCRIPTION you can alternatively set the description to a pre-fabricated value using PdfSignatureAppearance.SetLayer2Text.
In case of NAME_AND_DESCRIPTION, though, iText offers no way to inject a pre-calculated name.
A more general alternative is to create the signature appearance all by yourself, simply use GetLayer2 to retrieve a PdfFormXObject on which you can draw any visualization you like. In that case iText does not try and retrieve any signer information from the certificate.
QUESTION
You know how they say you don't need state management until you know you need it. Well turns out my project needs it. So I need some help wit best practice as I am adding ngxs to an existing angular project.
I have an action called getServiceDetail and my statemodel has a list of objects called DriverListsStopInfoViewModel. each of these objects have a unique ID. The html template of the consuming component uses a selector for the property currentStopDetail, which is a state property that gets set in my action.
GOAL:in my action I want to check the list of objects in my store to see if an object with the same id exists and return that object, and if it does not exist, call and api to get it.
EXAMPLE:The following code works, but I would like to hear if this is the right way to do it. do I even need to return the object from the action function if its found, or can I just use patch state to assign it to the currentStopDetail
...ANSWER
Answered 2020-Apr-27 at 02:22Short answer is yes, what you have done here is a typical way of handling this scenario (in my experience). There's a couple of improvements you could make:
do I even need to return the object from the action function if its found, or can I just use patch state to assign it to the currentStopDetail
No, you don't return anything from these action handlers, other than possibly an Observable that NGXS will handle (so in your case if there is no matching item found, you return the Observable that fetchs it from the API and patches the state).
Also when you do make the API call, you should only need a single update to the state:
