I'm passing data from one php page to another using this encryption class. It works well except when the encypted text contains a '+'. Then is does not get decrypted to the correct value. For instance this works:

myurl.com?id=w8P/EuU5OpuwprkDW6tbyX ...

But this does not:

myurl.com?id=EloTXvg1+8e8VJSV/hUREC ...

Any ideas? Fixes?

Thanks.

Jeff

I just needed to urlencode() the string. I'm fairly new to this...

Urlencoding is indeed the right solution as unencoded strings may loose some information when transported via http get.

Hi,

after:

function encrypt($string) {
$iv = $this->_generate_iv();

add:
$iv = strtr($iv, '+', 'h');

This replace "+" sign to "h" letter (You can use any letter/digit).

Hope this help's

Bye.
