Boa dia a todos, por favor estou tentando fazer uma assinatura digital em um XML, e esta dando super certo com a ajuda do exemples que Chris Glazier e Altair Borges me enviaram, porem esta assinando com o algoritimo RSA-SHA1 mas eu preciso assinar com algoritimo RSA-SHA256, eu achei um exemplo que eu acredite que seja o que eu preciso conforme esta abaixo em C#, mas não estou conseguindo converter o Visual COBOL for Visual Studio, se alguém conseguir me ajudar ficarei muito agradecido.

Bom dia Mr. Glazier
Infelizmente não deu certo, acho que analisei errado ou estou fazendo alguma coisa errada no programa, no meu XML eu tenho que assinar com algoritmo RSA-SHA256, mas o programa esta assinando com algoritmo RSA-SHA1, por isso pensei que poderia ser aquele método que converteu para mim ontem, mas não deu certo, vou anexar o programa como estou fazendo , e o XML de como assinou e um de como deve assinar, se o Senhor poder me ajudar mais uma vez ficarei muito grato.

Open up the Project Properties page and look on the Application tab. This is where you set the .NET Framework version. The list of supported Frameworks can change depending on which Visual Studio version you are using. I am using VS2017.
The actual assemblies need to be added as References in the References folder. If you expand this folder and select one of the assemblies you will see its properties if your property window is displayed.

Sorry but I did not understand this part "The actual assemblies need to be added as References in the References folder. If you expand this folder and select one of the assemblies you will see its properties if your property window is displayed."
I have to go to "project", "Add Reference", then open a screen, what do I need to do?

The example code that you provided makes use of .NET classes that are in non-default .NET assemblies. In order to make these classes available you must reference the assemblies.
RSAPKCS1SHA256SignatureDescription is a class whose full name is System.Deployment.Internal.CodeSigning.RSAPKCS1SHA256SignatureDescription.
At the top of the class I set the following directive:
$set ilusing"System.Deployment.Internal.CodeSigning"
This allows us to reference the class as RSAPKCS1SHA256SignatureDescription instead of specifying the full namespace.
The RSAPKCS1SHA256SignatureDescription class is found in the .NET Assembly System.Deployment.dll. In order to find the class you have to add a reference to this assembly in your project. You can do this by right-clicking on the References folder in the project and selecting Add Reference and then navigate to System.Deployment in the list of .NET assemblies and select it and click on OK. It will then show up in the list as shown below:

Good afternoon, i´m completes the Project(in annex) and is working perfectly, but when compiling it is generating an executable .exe, I need to be generated .dll so I can call this routine from another program, how should I proceed to solve this.
thank you

Open up the Project Properties page and on the Application tab change the Output type from Console Application to Class Library. Then it will generate a .dll.

Hello Mr. Glazier, I have already done this, but I do not even get into the routines, because neither the "Stop" that I put in the beginning does not process, and also not of the error, I am using the attached example.

What error are you receiving on the call statement, a COBOL RTS 173?
Are you stepping thru the code in the debugger?
If the calling program is in a different project than the called program then you need to add a reference to the project containing the called program in the References folder of the project containing the calling program.
What is the project name of the project containing the called program, is it RTP-SGN1?
I suggest you take a look at the tutorial here:

Hello, it does not return any error, it simply does nothing, I only have this project of this routines I did to sign the xml, the calling program has no project, I just call the new routine by the command "call", the calling program does part of a system and is written in cobol and compiled by visual cobol for visual studio 3.0. It was a system in netExpress 3.1 that we recompiled in visual cobol for visual studio through command. cbllink -d -s -g xxx.cbl

What you appear to be trying to do is call a managed code .dll from a native code executable using the COBOL CALL statement. This will not work. If you compile the calling program as managed code then you can use the CALL statement to call a managed code .dll.
In order to call a managed code .dll from a native code executable you need to use CCW or COM Callable Wrapper, which means that you Register a COBOL class for use with COM Interop and then you can instantiate it and invoke its methods using the COM support in the native COBOL libraries. (OLE).
This is covered in the docs here:
There is also a KB article and demo here:

Good morning Mr. Glazier, thank you very much for the help that worked perfectly with your tips.
But I need to tease you a little bit with two things.
This is working perfectly on my machine, which is of unvoltage, but how should I proceed in the client, being that on my machine when compiling it records an item in the windows registry, but on the client I do not know how we should proceed;
another bestowal would be, these routines attached when I send the XML to sign, it shows the screen for me to choose the certificate, but I would need to do this only in the first XML, and the next one would be the same certificate, without the need to choose the certificate again , because several XMLs with the same certificate are signed, without the need to be choosing the certificate all the time, have that possibility?
thank you

For your second question about displaying the Certificate selection screen only for the first invocation, I would think that you could control this by passing a flag as a parameter to the method which could be set by the client which would indicate whether or not the selection screen should be shown. Then the code logic in the server could bypass that function if required.
For your first question regarding registering the server on a client machine on which Visual Studio is not installed, you would have a couple of options.
1. Register the assembly using the regasm.exe tool.
You can find out more on the Microsoft site here:
2. Use Reg-free COM. This involves creating a manifest file for the client and server containing information about the properties of the COM component. If you use this approach then you do not have to use regasm.exe to register your COM server in production. I have uploaded an example Visual COBOL solution that contains a client and a server project along with instructions within a readme file for setting this up. You can also find out more information about this by Googling regfree COM.
One such link you will find is here.

Thank you Mr. Glazier, but I continue with two doubts.
In the first question, I understand that I can pass parameter, but I need to know if the instace can save the chosen certificate the first time I call it to use in the others, because I do not know how to process to save this certificate, so that in other times I just sign with the same certificate you chose the first time.
In the second second question, the question is, I need to do this process even if the calling program is compiled by the same compiler, ie I have this routine that subscribes to .NET which is a project, but the caller is a native cobol (no project ) but compiled by the same "Visual Cobol for Visual Studio" compiler.
Thank you.

For the first question, do you wish to save the certificate for long-term storage on disk or in memory for the next invocation of the method from the same instance of the application?
If you store the certificate in the working-storage of the class then this is instance data and will be available to all methods and all invocations of this instance.
If you wish to store it on disk so that you can access it again, you might look at using the export and import methods of the X509Certificate class. The docs can be found here:
I am not an expert on certificates or how to manipulate them so I will not comment further on how to achieve this.
On your second question, the requirement to call managed code from a native application using COM has nothing to do with the product version being used. It is part of the Interop functionality of using native and managed code together in the same application. You would need to do this if NX was used to compile the client or Visual COBOL was used.

Thank you very much Mr. Glazier, with your help and dedication, we were able to complete our signature project with digital certificate of the XMLs.
If you need anything, we are at your disposal.
