About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
i	01101001
n	01101110
t	01110100
e	01100101
r	01110010
g	01100111
o	01101111
v	01110110
e	01100101
r	01110010
n	01101110
m	01101101
e	01100101
n	01101110
t	01110100
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011010 010110 111001 110100 011001 010111 001001 100111 011011 110111 011001 100101 011100 100110 111001 101101 011001 010110 111001 110100 011000 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
111001	5
110100	0
011001	Z
010111	X
001001	J
100111	n
011011	b
110111	3
011001	Z
100101	l
011100	c
100110	m
111001	5
101101	t
011001	Z
010110	W
111001	5
110100	0
011000	Y
010110	W
1100	w

When combined, these characters form the encoded string: "aW50ZXJnb3Zlcm5tZW50YWw="
