Module: ActiveSupport::Base64

Defined in:
activesupport/lib/active_support/base64.rb

Overview

Base64 provides utility methods for encoding and de-coding binary data using a base 64 representation. A base 64 representation of binary data consists entirely of printable US-ASCII characters. The Base64 module is included in Ruby 1.8, but has been removed in Ruby 1.9.

Class Method Details

+ (Object) decode64(data)

Decodes a base 64 encoded string to its original representation. 

 ActiveSupport::Base64.decode64("T3JpZ2luYWwgdW5lbmNvZGVkIHN0cmluZw==")
 # => "Original unencoded string"

def self.decode64(data)
  data.unpack("m").first
end

+ (Object) encode64(data)

Encodes a string to its base 64 representation. Each 60 characters of output is separated by a newline character. 

 ActiveSupport::Base64.encode64("Original unencoded string")
 # => "T3JpZ2luYWwgdW5lbmNvZGVkIHN0cmluZw==\n"

def self.encode64(data)
  [data].pack("m")
end

+ (Object) encode64s(value)

Encodes the value as base64 without the newline breaks. This makes the base64 encoding readily usable as URL parameters or memcache keys without further processing. 

 ActiveSupport::Base64.encode64s("Original unencoded string")
 # => "T3JpZ2luYWwgdW5lbmNvZGVkIHN0cmluZw=="

def Base64.encode64s(value)
  encode64(value).gsub(/\n/, '')
end
