Base64
6 instance methods
The Base64 module provides for the encoding (encode64, strict_encode64, urlsafe_encode64) and decoding (decode64, strict_decode64, urlsafe_decode64) of binary data using a Base64 representation.
Example
A simple encoding and decoding.
Example
require "base64" enc = Base64.encode64('Send reinforcements') # -> "U2VuZCByZWluZm9yY2VtZW50cw==\n" plain = Base64.decode64(enc) # -> "Send reinforcements"
The purpose of using base64 to encode data is that it translates any binary data into purely printable characters.
