akfbase64(1)                General Commands Manual               akfbase64(1)

NAME
       akfbase64 - base64 encoder and decoder

SYNOPSIS
       akfbase64 [options] [input file] [output file]
       akfbase64 -z [-u]

DESCRIPTION
       Base64 is a method to convert binary data into plain ASCII.

       When  no  input  files are given, the program reads from standard input
       and writes to standard output.  That means it can be used as a filter.

       For encoding it outputs up to 76 characters per line.  For decoding  it
       ignores spaces, line breaks and other control codes.

       The  variant  base64url  is  more  suitable  for  URLs  and file names.
       Instead of the characters '+' and '/' it uses '-' and '_'.

OPTIONS
       -h
       --help shows help

       --version
              show licensing information

       -u     encode as the variant base64url

       -n     no line breaks

       -m     encode in compatibility mode for uudecode(1) with head and foot.
              The input file must be provided.

       -d     decode (base64 or base64url)

       -z     outputs one line of random characters (/dev/urandom)
              No input file may be provided.  Can be combined with the  option
              -u.
