(** Base64 is a group of similar binary-to-text encoding schemes that represent
binary data in an ASCII string format by translating it into a radix-64
representation. It is specified in RFC 4648. *)

(** [decode s] decodes the string [s] that is encoded in base64 format.
Will leave trailing NULLs on the string, padding it out to a multiple
of 3 characters. *)

(** [encode s] encodes the string [s] into base64. If [pad] is false,
no trailing padding is added. *)
