Android app

Hello, i created an app in C# and now i want to have the same thing on android phone. The app must contain 5 input text (1 password). The fields must update while typing. While typeing something must be done using DES 64 CBC encryption, and the output must be the same as the C# app (i tried several online DES CBC but they result in a different output). I can't tell every detail, because i think this might be a good idea. So if you like to bid on this project, you must also be able to read C# code (to ensure output will be the same). I can provide a working VS 2015 project.
