Hey guys,

I'm wondering which mcrypt cipher will provide me with an encryted
string, that can afterwards be encrypted again and is transverable
without problems through an link in an e-mail.
I would like to encrypt some piece of information (up to 25 characters)
and send it to the user in an e-mail via a link like kilu.de?enc=... !
This doesn't work with |MCRYPT_XTEA or |MCRYPT_TWOFISH256, since they
create pretty special ASCII characters, that are not interpreted right!

What cipher would you suggest? Or would you suggest a whole different
method?

Regards,
Samy
