by chance I observed the following:
I've encoded a string "WE7896" and sometimes get back the encoded string with 2 trailing '==' like "ABCetc=="
if I decode "ABCetc==", I get my original string back ("WE7896"), no problem
next I want to decode the url segment of an url like "http://mysite.com/review/ABCetc==", BUT I get the "Disallowed Key Characters" error: so I've tried adding '\=' to the system/core/Input.php (@function _clean_input_keys), but that didn't make any difference.
right now, my solution is after encoding to replace the '==' like this:
Code:
$url_segment=str_ireplace("==","",$url_segment);
and I decode the the url segment 'ABCetc' nicely back into 'WE7896'
which works fine !
but seems strange to me
P.S.: I was able to repeat above using different $config['encryption_key'] strings
please advise
thanks
