 3.7 ‘basenc’: Transform data into printable data
 ================================================
 
 ‘basenc’ transforms data read from a file, or standard input, into (or
 from) various common encoding forms.  The encoded form uses printable
 ASCII characters to represent binary data.
 
    Synopses:
 
      basenc ENCODING [OPTION]... [FILE]
      basenc ENCODING --decode [OPTION]... [FILE]
 
    The ENCODING argument is required.  If FILE is omitted, reads input
 from stdin.  The ‘-w/--wrap’,‘-i/--ignore-garbage’, ‘-d/--decode’
 options of this command are precisely the same as for ‘base64’.  ⇒
 base64 invocation.
 
    Supported ENCODINGs are:
 
 ‘--base64’
      Encode into (or decode from with ‘-d/--decode’) base64 form.  The
      format conforms to RFC 4648#4
      (https://tools.ietf.org/search/rfc4648#section-4).  Equivalent to
      the ‘base64’ command.
 
 ‘--base64url’
      Encode into (or decode from with ‘-d/--decode’) file-and-url-safe
      base64 form (using ‘_’ and ‘-’ instead of ‘+’ and ‘/’).  The format
      conforms to RFC 4648#5
      (https://tools.ietf.org/search/rfc4648#section-5).
 
 ‘--base32’
      Encode into (or decode from with ‘-d/--decode’) base32 form.  The
      encoded data uses the ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ234567=’
      characters.  The format conforms to RFC 4648#6
      (https://tools.ietf.org/search/rfc4648#section-6).  Equivalent to
      the ‘base32’ command.
 
 ‘--base32hex’
      Encode into (or decode from with ‘-d/--decode’) Extended Hex
      Alphabet base32 form.  The encoded data uses the
      ‘0123456789ABCDEFGHIJKLMNOPQRSTUV=’ characters.  The format
      conforms to RFC 4648#7
      (https://tools.ietf.org/search/rfc4648#section-7).
 
 ‘--base16’
      Encode into (or decode from with ‘-d/--decode’) base16
      (hexadecimal) form.  The encoded data uses the ‘0123456789ABCDEF’
      characters.  The format conforms to RFC 4648#8
      (https://tools.ietf.org/search/rfc4648#section-8).
 
 ‘--base2lsbf’
      Encode into (or decode from with ‘-d/--decode’) binary string form
      (‘0’ and ‘1’) with the _least_ significant bit of every byte first.
 
 ‘--base2msbf’
      Encode into (or decode from with ‘-d/--decode’) binary string form
      (‘0’ and ‘1’) with the _most_ significant bit of every byte first.
 
 ‘--z85’
      Encode into (or decode from with ‘-d/--decode’) Z85 form (a
      modified Ascii85 form).  The encoded data uses the
      ‘0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTU VWXYZ.-:+=^!/*?&<>()[]{}@%$#’.
      characters.  The format conforms to ZeroMQ spec:32/Z85
      (https://rfc.zeromq.org/spec:32/Z85/).
 
      When encoding with ‘--z85’, input length must be a multiple of 4;
      when decoding with ‘--z85’, input length must be a multiple of 5.
 
    Encoding/decoding examples:
 
      $ printf '\376\117\202' | basenc --base64
      /k+C
 
      $ printf '\376\117\202' | basenc --base64url
      _k-C
 
      $ printf '\376\117\202' | basenc --base32
