Base64 Encoding

Base64 converts ordinary text into an ASCII-safe encoded string and back again.

base64_encoding.rb

require "base64"

text = 
encoded = Base64.strict_encode64(text)
decoded = Base64.decode64(encoded)

round_trip = decoded == text

puts "text=#{text}"
puts "encoded=#{encoded}"
puts "round_trip=#{round_trip}"

require "base64"

text = 
encoded = Base64.strict_encode64(text)
decoded = Base64.decode64(encoded)

round_trip = decoded == text

puts "text=#{text}"
puts "encoded=#{encoded}"
puts "round_trip=#{round_trip}"

require "base64"

text = 
encoded = Base64.strict_encode64(text)
decoded = Base64.decode64(encoded)

round_trip = decoded == text

puts "text=#{text}"
puts "encoded=#{encoded}"
puts "round_trip=#{round_trip}"

base64 Base64 is an encoding format, not encryption; decoding returns the original text.
