PhP encryption

Hello,

I would like to encrypt a password and send it by email, so I will be able to see it only if I decrypt it.

Can you help me on this?

Thanks

Propably the following functions will be usefull for you :

md5()
base64_encode()
mcrypt()

For more information check the manual at php.net using the function name as the uri eg : http://www.php.net/md5

md5 wont be useful for you if you want to decrypt it. I suggest base64_encode().

There are other encryptions you can use besides base64, just search google.
