"+" sign in the encrypted string

[AsaadMamoun]

Hi there

I am developing an app where the username/password should be encrypted on android device and decrypted on .net web service. The issue is that some time I'm getting the plus '+' sign in the encrypted string which leads to error. Is that normal ? how to get rid of it without breaking the app ? I'm using the same public key and IV on app and server.

Thanks.
