Zend cookie encrypt and decrypt not returning same value

[mrconfused786]

Hello,

First, thanks for looking at this post. I need help understanding why \Zend_Filter_Encrypt and \Zend_Filter_Decrypt is not returning the initial string that's being stored in a cookie.

I'm using my own Cookie to store user credentials.
