PHP: What to use for email confirmation code?

Question

I first tried base64 to encode mail@domain.com but it includes / which breaks my URL which is as http://example.com/verify/<confirmation_code>

I don't want to store in Db, I want on the fly process,provided I can pass my own Salt. What should I use?

Answer 1

您可以对用户ID进行编码，然后将其作为确认代码发送到该位置，以便在其中检查该ID。

Answer 2

I use base_64 for encoding image inks to send to a resizing script this is 1 of the encryptions...

there is no slashes in base_64... are you using base64_encode to encrypt and base64_decode to decrypt?
