NAME

       basenc - Encode/decode data and print to standard output


SYNOPSIS

       basenc [OPTION]... [FILE]


DESCRIPTION

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

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

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

       --base64
              same as 'base64' program (RFC4648 section 4)

       --base64url
              file- and url-safe base64 (RFC4648 section 5)

       --base32
              same as 'base32' program (RFC4648 section 6)

       --base32hex
              extended hex alphabet base32 (RFC4648 section 7)

       --base16
              hex encoding (RFC4648 section 8)

       --base2msbf
              bit string with most significant bit (msb) first

       --base2lsbf
              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

       --version
              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.
