I don't see what you mean by " but I cannot encrypt the whole
string...unless i replaced the & with another character" ? I tested your
code by calling this:
$enc =
encrypt("PassedUserName='Hester'&PassedUserOccupation='Tester'","volatile");
$dec = decrypt($enc,"volatile");
echo "$enc<br>$dec";

Here is the output:
icbQ39TZzcHY2+G6wuHOqYy+1N/V2duTi5q/zdTnztC66dTesNfM4dXX49XQ4qaTudvi4MbmkA==PassedUserName='Hester'&PassedUserOccupation='Tester'On some other page I would then get the result (after decrypting$_GET['PassedData']) with a simple $result = split('&', $dec)... urlencodeand urldecode may also be useful if you want to include & into someparameter.Dae<plittle1970@hotmail.com> wrote in messagenews:1118052949.490444.204450@g47g2000cwa.googlegroups.com...> Hi there.
