Encryption key file password

Hi all,

I've implemented a .dll to distribute a matlab package into a software by using deploytool. Everything was done passing through .NET component since the software is written in C#. I've generated through the function pcode all the necessary .p files. MCR was also added

Given these premises my question is: how to properly protect and distribute the matlab package into someone else's software? the deploytool ask me for an ecryption key file which I don't have generated. How to include passwords, encryption files or something useful for my case?

thank you all

best
