NAME
       base32::hex - base32 extended hex encoding

SYNOPSIS
       package require Tcl  8.4

       package require base32::core  ?0.1?

       package require base32::hex  ?0.1?

       ::base32::hex::encode string

       ::base32::hex::decode estring

_________________________________________________________________

DESCRIPTION
       This  package  provides	commands  for encoding and decoding of strings
       into and out of the extended hex base32 encoding as  specified  in  the
       RFC 3548bis draft.

API
       ::base32::hex::encode string
	      This command encodes the given string in extended hex base32 and
	      returns the encoded string as its	 result.  The  result  may  be
	      padded  with the character = to signal a partial encoding at the
	      end of the input string.

       ::base32::hex::decode estring
	      This commands takes the estring and decodes it under the assump‐
	      tion  that it is a valid extended hex base32 encoded string. The
	      result of the decoding is returned as the result of the command.

	      Note that while the encoder will generate only uppercase charac‐
	      ters this decoder accepts input in lowercase as well.

	      The  command  will  always  throw an error whenever encountering
	      conditions which signal some type of bogus input, namely if

	      [1]    the input contains characters which are not valid	output
		     of a extended hex base32 encoder,

	      [2]    the length of the input is not a multiple of eight,

	      [3]    padding  appears not at the end of input, but in the mid‐
		     dle,

	      [4]    the padding has not of length six, four,  three,  or  one
		     characters,

CODE MAP
       The  code  map used to convert 5-bit sequences is shown below, with the
       numeric id of the bit sequences to the left and the character  used  to
       encode  it to the right. The important feature of the extended hex map‐
       ping is that the first 16 codes map to the digits and hex characters.
