"Y64 is a base64 variant used at Yahoo! when base64 information needs to
be transmitted as part of a GET request. Regular base64 has three
characters that aren’t URL-safe: plus (+), slash (/), and equals (=).
Y64 encoding replaces these with dot (.), underscore (_), and dash (-),

Or would case sensitivity be too crazy?
