NAME         top

       basenc - Encode/decode data and print to standard output

SYNOPSIS         top

       basenc [OPTION]... [FILE]

DESCRIPTION         top

       basenc encode or decode FILE, or standard input, to standard

       With no FILE, or when FILE is -, read standard input.

       Mandatory arguments to long options are mandatory for short
       options too.

              same as 'base64' program (RFC4648 section 4)

              file- and url-safe base64 (RFC4648 section 5)

              same as 'base32' program (RFC4648 section 6)

              extended hex alphabet base32 (RFC4648 section 7)

              hex encoding (RFC4648 section 8)

              bit string with most significant bit (msb) first

              bit string with least significant bit (lsb) first

       -d, --decode
              decode data

       -i, --ignore-garbage
              when decoding, ignore non-alphabet characters

       -w, --wrap=COLS
              wrap encoded lines after COLS character (default 76).  Use
              0 to disable line wrapping

       --z85  ascii85-like encoding (ZeroMQ spec:32/Z85); when encoding,
              input length must be a multiple of 4; when decoding, input
              length must be a multiple of 5

       --help display this help and exit

              output version information and exit

       When decoding, the input may contain newlines in addition to the
       bytes of the formal alphabet.  Use --ignore-garbage to attempt to
       recover from any other non-alphabet bytes in the encoded stream.

              $ printf '\376\117\202' | basenc --base32hex

              $ printf '\376\117\202' | basenc --base16

              $ printf '\376\117\202' | basenc --base2lsbf

              $ printf '\376\117\202' | basenc --base2msbf

              $ printf '\376\117\202\000' | basenc --z85
