[PHP] MD5 / crypt

[Dan Harrington]

Hello,

What is the best way to encrypt/decrypt strings when passing between php
pages?

I am using md5 and currently get strings that produce "unprintable"
characters
or characters like slashes or other things that could interfere with the
passing
between php pages. (e.g.
http://server.asdf/action.php?args=encryptedstring )

e.g.
5V"g\7`Qv1Sc]aV&Q4a
6#bW>SbU!f_4V1QvPaUe 5Q!c b

versus

something like:
fdsay98fdsa25ht4636ussd9fg3245ijrg9u341271234hjas897rewq

I really would like to restrict everything to 0-9,a-z,A-Z characters so
the encrypted string is "friendly" :-)

Thanks
Dan
