Hello,
I am looking for a php function or script to encode a string and decode it
(when required). Your help would be greatly appreciated.
have thought of "md5" but the resulting string cant be decoded again!
crc32 and sha1 functions are not good either.
The function crypt () is also a One-way string encryption .. so that would not
work as well.
What I need it for is simply to encode (encrypt) a user's email - which now
appears on the web page as is - and when someone clicks a link to contact that
user, the script would decode it back to the proper email string. Hence the
sender would not actually know the email address.
There are ways to do it via mysql database but I thought if a I could do the
crypting (and then decoding) via pure php script, it would ne less of a lod on
the mysql db.
Any suggestions would be greatly appreciated. It is a bit urgent.
Best regards David
