NAME

     base64 -- Encode and decode using Base64 representation

SYNOPSIS

     base64 [-d | -h | -v | -D] [-b count] [-i input_file] [-o output_file]

DESCRIPTION

     base64 encodes and decodes Base64 data, as specified in RFC 4648. With no options, base64 reads raw data from stdin and writes encoded data
     as a continuous block to stdout.

OPTIONS

     The following options are available:
     -b count
     --break=count	  Insert line breaks every count characters. Default is 0, which generates an unbroken stream.

     -d
     --debug		  Print verbose log messages during processing.

     -D
     --decode		  Decode incoming Base64 stream into binary data.

     -h
     --help		  Print usage summary and exit.

     -i input_file
     --input=input_file   Read input from input_file.  Default is stdin; passing - also represents stdin.

     -o output_file
     --output=output_file
			  Write output to output_file.	Default is stdout; passing - also represents stdout.

     -v
     --version		  Print build version and exit.

NAME

       base64 - base64-encode/decode binary data

SYNOPSIS

       package require Tcl  8

       package require base64  ?2.4.2?

       ::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string

       ::base64::decode string

_________________________________________________________________

DESCRIPTION

       This package provides procedures to encode binary data into base64 and back.

       ::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string
	      Base64  encodes  the  given  binary string and returns the encoded result. Inserts the character wrapchar every maxlen characters of
	      output. wrapchar defaults to newline. maxlen defaults to 76.

	      Note well: If your string is not simple ascii you should fix the string encoding before doing base64 encoding. See the examples.

	      The command will throw an error for negative values of maxlen, or if maxlen is not an integer number.

       ::base64::decode string
	      Base64 decodes the given string and returns the binary data.  The decoder ignores whitespace in the string.

EXAMPLES

       % base64::encode "Hello, world"
       SGVsbG8sIHdvcmxk

       % base64::encode [string repeat xyz 20]
       eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6
       eHl6eHl6eHl6
       % base64::encode -wrapchar "" [string repeat xyz 20]
       eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6

       # NOTE: base64 encodes BINARY strings.
       % set chemical [encoding convertto utf-8 "Cu2088Hu2081u2080Nu2084Ou2082"]
       % set encoded [base64::encode $chemical]

       % set caffeine [encoding convertfrom utf-8 [base64::decode $encoded]]
