# ActiveSupport::Base64

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.

### Public Class Methods

decode64(data) click to toggle source

Decodes a base 64 encoded string to its original representation.

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

    # File lib/active_support/base64.rb, line 28
    def self.decode64(data)
      data.unpack("m").first
    end

encode64(data) click to toggle source

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"

    # File lib/active_support/base64.rb, line 20
    def self.encode64(data)
      [data].pack("m")
    end

encode64s(value) click to toggle source

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=="

    # File lib/active_support/base64.rb, line 39
    def Base64.encode64s(value)
      encode64(value).gsub(/\n/, '')
    end
