How to digitally sign an xml document

David Williams · Post by **David Williams** » Thu Apr 12, 2018 3:07 pm

I want to sign a xml document using a P12 certificate in a FWXH application. Does anyone have a sample program or code extract to do this?
I found an article on the Microsoft site which has a full example in C# and an example in Java on another site. The problem is I wouldn't know where to start trying to convert C# or Java.

Any help would be appreciated.

TIA
David

David,

This seems to be a good example:

Antonio,

A resource to sign xml files using certified through FWH will be very usefully.

David,

Have you been able to implement that C code ?

Antonio,

Thank you for that link. I'm leaning towards the C version, as I have used Openssl before. I also have C# and VB examples so I need to make up my mind

.

I hope to get going on it this week. I'll update you then.

Regards
David
