[ianrussel]

Hi, I am using this wonderful package,. I used this in cUrling some data after registration,.It will just give me the valid token when dumping.But I notice that this will output error like below when I hit back button or go back to registration page again. In registration page, I have a function that will fetch a json data if credentials are valid. emails and password is decrypted tru this package

InvalidArgumentException in Simple.php line 36:
Encryption key must be exactly 32 bytes long.
