encrypt password and account number

Browse Source 
* the encryption uses a unique machine key, this means that if anyone steals config.otml with a saved password,
he will not be able to decrypt the password without the machine UUID key
* the encrypt uses a simple XOR encryption method, encoded with base64 and adler32 summing
