# frozen_string_literal: true
#
# \Module \Base64 provides methods for:
#
# - Encoding a binary string (containing non-ASCII characters)
# as a string of printable ASCII characters.
# - Decoding such an encoded string.
#
# \Base64 is commonly used in contexts where binary data
# is not allowed or supported:
#
# - Images in HTML or CSS files, or in URLs.
# - Email attachments.
#
# A \Base64-encoded string is about one-third larger that its source.
# See the {Wikipedia article}[https://en.wikipedia.org/wiki/Base64]
# for more information.
#
# This module provides three pairs of encode/decode methods.
# Your choices among these methods should depend on:
#
# - Which character set is to be used for encoding and decoding.
# - Whether "padding" is to be used.
# - Whether encoded strings are to contain newlines.
#
# Note: Examples on this page assume that the including program has executed:
#
# require 'base64'
#
# == Encoding Character Sets
#
# A \Base64-encoded string consists only of characters from a 64-character set:
#
# - <tt>('A'..'Z')</tt>.
# - <tt>('a'..'z')</tt>.
# - <tt>('0'..'9')</tt>.
# - <tt>=</tt>, the 'padding' character.
# - Either:
# - <tt>%w[+ /]</tt>:
# {RFC-2045-compliant}[https://datatracker.ietf.org/doc/html/rfc2045];
# _not_ safe for URLs.
# - <tt>%w[- _]</tt>:
# {RFC-4648-compliant}[https://datatracker.ietf.org/doc/html/rfc4648];
# safe for URLs.
#
# If you are working with \Base64-encoded strings that will come from
# or be put into URLs, you should choose this encoder-decoder pair
# of RFC-4648-compliant methods:
#
# - Base64.urlsafe_encode64 and Base64.urlsafe_decode64.
#
# Otherwise, you may choose any of the pairs in this module,
# including the pair above, or the RFC-2045-compliant pairs:
#
# - Base64.encode64 and Base64.decode64.
# - Base64.strict_encode64 and Base64.strict_decode64.
#
# == Padding
#
# \Base64-encoding changes a triplet of input bytes
# into a quartet of output characters.
#
# <b>Padding in Encode Methods</b>
#
# Padding -- extending an encoded string with zero, one, or two trailing
# <tt>=</tt> characters -- is performed by methods Base64.encode64,
# Base64.strict_encode64, and, by default, Base64.urlsafe_encode64:
#
# Base64.encode64('s') # => "cw==\n"
# Base64.strict_encode64('s') # => "cw=="
# Base64.urlsafe_encode64('s') # => "cw=="
# Base64.urlsafe_encode64('s', padding: false) # => "cw"
#
# When padding is performed, the encoded string is always of length <em>4n</em>,
# where +n+ is a non-negative integer:
#
# - Input bytes of length <em>3n</em> generate unpadded output characters
# of length <em>4n</em>:
#
# # n = 1: 3 bytes => 4 characters.
# Base64.strict_encode64('123') # => "MDEy"
# # n = 2: 6 bytes => 8 characters.
# Base64.strict_encode64('123456') # => "MDEyMzQ1"
#
# - Input bytes of length <em>3n+1</em> generate padded output characters
# of length <em>4(n+1)</em>, with two padding characters at the end:
#
# # n = 1: 4 bytes => 8 characters.
# Base64.strict_encode64('1234') # => "MDEyMw=="
# # n = 2: 7 bytes => 12 characters.
# Base64.strict_encode64('1234567') # => "MDEyMzQ1Ng=="
#
# - Input bytes of length <em>3n+2</em> generate padded output characters
# of length <em>4(n+1)</em>, with one padding character at the end:
#
# # n = 1: 5 bytes => 8 characters.
# Base64.strict_encode64('12345') # => "MDEyMzQ="
# # n = 2: 8 bytes => 12 characters.
# Base64.strict_encode64('12345678') # => "MDEyMzQ1Njc="
#
# When padding is suppressed, for a positive integer <em>n</em>:
#
# - Input bytes of length <em>3n</em> generate unpadded output characters
# of length <em>4n</em>:
#
# # n = 1: 3 bytes => 4 characters.
# Base64.urlsafe_encode64('123', padding: false) # => "MDEy"
# # n = 2: 6 bytes => 8 characters.
# Base64.urlsafe_encode64('123456', padding: false) # => "MDEyMzQ1"
#
# - Input bytes of length <em>3n+1</em> generate unpadded output characters
# of length <em>4n+2</em>, with two padding characters at the end:
#
# # n = 1: 4 bytes => 6 characters.
# Base64.urlsafe_encode64('1234', padding: false) # => "MDEyMw"
# # n = 2: 7 bytes => 10 characters.
# Base64.urlsafe_encode64('1234567', padding: false) # => "MDEyMzQ1Ng"
#
# - Input bytes of length <em>3n+2</em> generate unpadded output characters
# of length <em>4n+3</em>, with one padding character at the end:
#
# # n = 1: 5 bytes => 7 characters.
# Base64.urlsafe_encode64('12345', padding: false) # => "MDEyMzQ"
# # m = 2: 8 bytes => 11 characters.
# Base64.urlsafe_encode64('12345678', padding: false) # => "MDEyMzQ1Njc"
#
# <b>Padding in Decode Methods</b>
#
# All of the \Base64 decode methods support (but do not require) padding.
#
# \Method Base64.decode64 does not check the size of the padding:
#
# Base64.decode64("MDEyMzQ1Njc") # => "01234567"
# Base64.decode64("MDEyMzQ1Njc=") # => "01234567"
# Base64.decode64("MDEyMzQ1Njc==") # => "01234567"
#
# \Method Base64.strict_decode64 strictly enforces padding size:
#
# Base64.strict_decode64("MDEyMzQ1Njc") # Raises ArgumentError
# Base64.strict_decode64("MDEyMzQ1Njc=") # => "01234567"
# Base64.strict_decode64("MDEyMzQ1Njc==") # Raises ArgumentError
#
# \Method Base64.urlsafe_decode64 allows padding in +str+,
# which if present, must be correct:
# see {Padding}[Base64.html#module-Base64-label-Padding], above:
#
# Base64.urlsafe_decode64("MDEyMzQ1Njc") # => "01234567"
# Base64.urlsafe_decode64("MDEyMzQ1Njc=") # => "01234567"
# Base64.urlsafe_decode64("MDEyMzQ1Njc==") # Raises ArgumentError.
#
# == Newlines
#
# An encoded string returned by Base64.encode64 or Base64.urlsafe_encode64
# has an embedded newline character
# after each 60-character sequence, and, if non-empty, at the end:
#
# # No newline if empty.
# encoded = Base64.encode64("\x00" * 0)
# encoded.index("\n") # => nil
#
# # Newline at end of short output.
# encoded = Base64.encode64("\x00" * 1)
# encoded.size # => 4
# encoded.index("\n") # => 4
#
# # Newline at end of longer output.
# encoded = Base64.encode64("\x00" * 45)
# encoded.size # => 60
# encoded.index("\n") # => 60
#
# # Newlines embedded and at end of still longer output.
# encoded = Base64.encode64("\x00" * 46)
# encoded.size # => 65
# encoded.rindex("\n") # => 65
# encoded.split("\n").map {|s| s.size } # => [60, 4]
#
# The string to be encoded may itself contain newlines,
# which are encoded as \Base64:
#
# # Base64.encode64("\n\n\n") # => "CgoK\n"
# s = "This is line 1\nThis is line 2\n"
# Base64.encode64(s) # => "VGhpcyBpcyBsaW5lIDEKVGhpcyBpcyBsaW5lIDIK\n"
