How to handle "+" in url

I need to pass parameter via URL that is encrypted. The encryption algorithim adds +.

Here's an example "8ckRrw+FhCE=". When this parameter is read it creates a space like this 8ckRrw FhCE=. URLDecoder interprets + as space. Is there anyway to handle such a situation.

Thanks in advance for your response.
