javax.crypto different in Linux and Windows?

[Emili Calonge]

Hi all,

I'm developing somne app and I've got two computers, one uses Windows and the other uses Linux. The thing is that I have to autenticate users using a database and I use javax.crypto to crypt the passwords.

In windows I can create users and then autenticate them, in Linux, I can create users but they never autneticate. I have to think that the problem is related with the crypto functions behaviour under different os's. Is that possible?

my code to encode the password is the following:

  
String pass = "password";
byte[] password2 = password.getBytes();
byte[] clau = pass.getBytes();
byte[] encrypted = cryptAES_CBC(password2, clau, Cipher.ENCRYPT_MODE);

The two platforms most likely have different default encodings, so that the getBytes() method returns different values. Try using the getBytes(String) method instead.

I suppose you're right, but I can't manage to fix it. I've tried using getBytes("UTF-8"); but it doesn't work either.

The thing is really strange though. In linux it doesn't work if I create a new user and I try to log in with it. And the password encryption is made on linux, so it should be the same, but it's not... I don't get it.
