Public Class Methods

urlsafe_decode64(str) click to toggle source

Returns the Base64-decoded version of str. This method complies with “Base 64 Encoding with URL and Filename Safe Alphabet” in RFC 4648. The alphabet uses ‘-’ instead of ‘+’ and ‘_’ instead of ‘/’. @note This method will be defined only on ruby 1.8 due to its absence in stdlib.

# File lib/el_finder/base64.rb, line 19
def self.urlsafe_decode64(str)
  str.tr("-_", "+/").unpack("m0").first
end

urlsafe_encode64(bin) click to toggle source

Returns the Base64-encoded version of bin. This method complies with “Base 64 Encoding with URL and Filename Safe Alphabet” in RFC 4648. The alphabet uses ‘-’ instead of ‘+’ and ‘_’ instead of ‘/’. @note This method will be defined only on ruby 1.8 due to its absence in stdlib.

# File lib/el_finder/base64.rb, line 13
def self.urlsafe_encode64(bin)
  [bin].pack("m0").tr("+/", "-_")
