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] Q+KCiEjigoHigoBO4oKET+KCgg== % set caffeine [encoding convertfrom utf-8 [base64::decode $encoded]] BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems.
