I´m new working with liveCycle, and I would like to know how it works at technical level.
I appreciate someone explain a bit about it or send a link to a page with detailed information.
Your question is pretty broad...
What are you trying to achieve with your workflow? For example, do you want to...
Generate Digital Certificates (self-signed or otherwise)
Have end users digitally sign PDF document or forms (with Acrobat Pro or Reader)
Have the PDF document or forms digitally signed on the server side
Validate the digital signature on the client
Validate the digital signature on the server side
I have attached a document that should help as well.
