Our products Aloaha PDF Suite / Aloaha PDF Editor are based on the Aloaha PDF SDK. This SDK contains some very easy to script interfaces. These Interfaces are allowed to be used by licensed user. Just as a short example how easy to use our API's are I will publish a sample script below. Please contact support if you need more details.
Aloaha PDF Suite / Aloaha PDF Editor is able to digitally sign your PDF documents Adobe.PPKMS compatible. Adobe.PPKMS signed documents can be verified and validated with the PDF Reader. You might need to validate/verify PDF Documents from your ASP page to allow only signed documents to be uploaded. Please find below a small vbs as a demonstration.
