sqlite encryption in windows phone 8.1

i am developing apps for windows phone 8.1 using visual studio 2014 update 4 i am also using sqlite database from nuget source to store data.I want to password encrypt my database file, i got libraries such as open ssl and sqlenrypt but they are paid which i cannot afford.can anyone help me out with free library. I have also checked out with sqlcipher(one of the open source library) but i didnt got any points to merge it with my project.if other libraries are also there than please provide me with steps to integrate with project.
