What type of encryption does Win2PDF Pro support?
Win2PDF Pro uses encryption that is defined by Adobe in the PDF specification. It uses RC4 encryption when 40 bit encryption is enabled, and it uses AES encryption when 128 bit encryption is enabled. You can verify the encryption type by viewing the "Security" tab of the PDF properties when viewing the file in Adobe Reader.
