if i have a web service, written in .NET, is there a common way to encrypt/decrypt data so they can be read by my android app? Do they share common methods? The web service is SOAP and i use KSOAP2 for the data. Thanks in advance.
However the device may need to know the passwords to decrypt it unless you are using a public/private keys and you hold the public key. But then it only gives you the authentication or certification of what is sent.
