I'm a computer science student  and I'm working on "an Android App that Encrypt and Decrypt messages between users" , and I'm little be lost and confused , and while searching here and there , I stumbled into "AeroGear Crypto Java" on "github" and I was reading it and  found it really interesting , and since your email was there , I decided to contact you !   I'm wondering if I can get few minutes of your time to ask you on how to implement "AereoGear" in order to the users to exhange Encrypted messages .
