Java 8 Base64 provides a standard way to do Base64 encoding and decoding.
There are three types of Base64 encoding:
– Basic: Encoder produces a set of characters within A-Za-z0-9+/. Decoder rejects any character NOT mapped to A-Za-z0-9+/.
– URL: Encoder produces a URL or safe filename which is set of characters within A-Za-z0-9+_.
– MIME: Output is mapped to MIME friendly format.
