The hosting server just wont execute:
SignedXml.ComputeSignature();
I thought fromXML and toXML methods required full trust. But this came as a surprise. Now it is impossible to digitally sign any document.
On searching the net I found this:
Using RSA Public Key Encryption in a Shared Web Hosting Environment
Anyone used this before or any other way out?
I was eventually able to develop the online activation system using Bounty Castle security API’s.
There is not a direct method available, but the base API can be used to generate a digital signature.
