How to convert XPS to PDF and encrypt it by 128 bit AES encryption?

When you need to convert XPS to PDF and encrypt output PDF by 128 bit AES encryption, maybe you can have a free trial of software VeryDOC XPS to PDF Converter, by which you can make it easily. AES has been adopted by the U.S. government and is now used worldwide. AES is a variant of Rijndael which has a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. AES 128 bit is adopted by Acrobat 7 or higher version. After encryption, the output PDF will be much more safer to be transferred to your clients, customers or others.
