BASE32(1)                        User Commands                       BASE32(1)

NAME
       base32 - base32 encode/decode data and print to standard output

SYNOPSIS
       base32 [OPTION]... [FILE]

DESCRIPTION
       Base32 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.

       -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

       --help display this help and exit

       --version
              output version information and exit

       The  data are encoded as described for the base32 alphabet in RFC 4648.
       When decoding, the input may contain newlines in addition to the  bytes
       of  the formal base32 alphabet.  Use --ignore-garbage to attempt to re‐
       cover from any other non-alphabet bytes in the encoded stream.
