I was reading this article which talks about a design to shorten urls, and in the design section it says that the given url can be hashed using an hashing algorithm such as MD5, and then be encoded for display purposes using base64 or similar encoding.
I am confused so as to why would we need to encode an encrypted string. Is it not safe to display an MD% hash, or is there any other benefit? Can anyone shed some light on this? I tried searching online, and a lot of pages talk about encryption, etc but not about the above scenario.
