simple encryption algorithm for numbers

Question

I'm working on a project that take the GPS location every 5 seconds and send it to the server, but i need to make a little of security, so i need to encrypt the location in android device and decrypt it in server side, so i'm searching for a simple algorithm to do this Thanks in advance

Answer 1

The ideas for you to try:

1. Send your data over HTTPS. It will add the layer of security you need and it's one of the simplest methods available.
2. Use Java Encryption API with asymmetric cryptographic algorithm like RSA. You should probably avoid using AES or similar symmetric algorithm because you should not store passphrase in your Android app - it could be quite easily compromised.
