# = base64.rb: methods for base64-encoding and -decoding strings
#

# 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.
#
#     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.

module Base64
  module_function

# Returns the Base64-encoded version of +bin+.
  # This method complies with RFC 2045.
  # Line feeds are added to every 60 encoded characters.
  #
  #    require 'base64'
  #    Base64.encode64("Now is the time for all good coders\nto learn Ruby")

  # non-alphabet characters.  Note that CR or LF are also rejected.
  def strict_decode64(str)
    str.unpack("m0").first
  end

# 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 that the result can still contain '='.
  # You can remove the padding by setting +padding+ as false.
  def urlsafe_encode64(bin, padding: true)
    str = strict_encode64(bin).tr("+/", "-_")
    str = str.delete("=") unless padding

  # This method complies with ``Base 64 Encoding with URL and Filename Safe
  # Alphabet'' in RFC 4648.
  # The alphabet uses '-' instead of '+' and '_' instead of '/'.
  #
  # The padding character is optional.
  # This method accepts both correctly-padded and unpadded input.
  # Note that it still rejects incorrectly-padded input.
  def urlsafe_decode64(str)
